The LORRIC clamp-on ultrasonic flowmeter uses the ultrasonic time difference to measure the flow, and uses the linear relationship between the ultrasonic transmission time difference between the upstream and downstream of the pipe and the flow rate to measure the flow. Due to the one-piece clamp-on structure, it can be installed without interventions in the pipe, compared with the in-line flowmeter, it can also provide the highest chemical resistance and leak-proof performance. Compared with the traditional ultrasonic flowmeter, since there is no need to adjust the position of the upstream and downstream probes, it can be installed quickly, and also greatly reduces the training required for installers.
This product uses ultrasonic measurement, so it is necessary to avoid the interference of ultrasonic transmission caused by a large number of solid foreign objects, a large number of air bubbles, and crystals in the fluid. At the same time, try to avoid strong magnetic field interference near the device.
This product provides flow measurement of liquids that do not contain a large amount of impurities in full pipe in industrial environments. The installation location should allow the fluid in the pipe to be as stable and fully developed as possible. The temperature of the pipe can be up to 100 degrees Celsius, but the ambient temperature should allow the device to work between -10 and 60 degrees Celsius. The device also provides IP66 water repellent design and cannot be used under water. The product material is PC, PMMA, PPS, PA66, stainless steel 304 and PEEK, which can resist light chemicals, but should not be exposed to chemicals for a long time or in large quantities.
In order to reduce the difficulty of installation, each model corresponds to a range of pipe outer diameters. Please select the model according to the pipe specifications to be installed. Some combinations of pipe materials and wall thicknesses that are unfavorable for ultrasonic transmission may make it difficult to measure the flow rate (for example, too thick PVDF pipes or some metal pipes). Please consult the sales staff before purchasing.

Product aging under long-term UV exposure.
If any of the scenarios below occur and cause damage to the flowmeter, the warranty is void.
If the device material is PC then it is not highly resistant to PVC glue which is a strong gas and lubricant for PVC pipe. Therefore, before installing the flowmeter you must ensure that the glue is dry between the connecting pipe and adapter.
Please pay special attention to the vertical flow of solvents and chemicals outside the pipeline since it may potentially cause damage to the flowmeter
Do not use this device as a support point for pipelines or other objects, which will cause the flowmeter to withstand external forces which it is not designed for, thus , shortening the usage life of the product or damaging it.
During the installation process, it’s crucial to tighten the union nuts only by hand until the flowmeter does not move and rotate. Do not use iron pliers or other tools to avoid damage to the flowmeter.
The flowmeter is not permanently fixed to the outside of the pipeline, and can still move and rotate under excessive external force. Please do not use the flowmeter as a structure for personnel fixing, moving and safety protection.
The electronic device of the flowmeter is not UV resistant. Therefore, we suggest covering it with a protector if installed outdoors.
The seller will not be responsible for free maintenance for any defect or malfunction incurred by improper use and human errors.
If the flowmeter is transported with its piping system to another site without protection then it could be damaged.
The 1st principle for choosing an installation location is wherein the pipe is filled completely with liquid to avoid issues caused by air bubbles or precipitation in the pipe. The 2nd principle is allowing the flow in the pipe to be fully developed by having enough length on both sides of the straight pipe. This means no equipment should be left on either side like adaptors, elbow pipe, valves or pumps.
The LCD display screen should not be exposed to direct sunlight that could cause visibility issues and a shorter life usage. Therefore, installing the flowmeter under direct sunlight should be avoided or with a sunlight protector is recommended.
Please choose the vertical pipe with a bottom-up flow direction.
Please choose the location with full liquid, like the lower part of the inclined pipe.
LORRIC’s EchoSense flow meter should not be installed at the top right or bottom side of the pipe in order to avoid the interruption of air bubbles or precipitation.
If the installation location for the flowmeter is close to a tank where pressure is low. We recommend installing a valve at the pipe exit to avoid generating any air bubbles.
If air bubbles are frequently generated in the pipe, it may lead to a large non-reproducible measurement error which should be avoided.
Make sure that the buckle is in the released position.
After the device faces the intended operation direction, pre-lock the device and the buckle on both sides of the pipeline with screws. At this time, if it is a large pipe in the applicable pipeline, the device may not move. If it is a small pipe in the applicable pipeline and the device is still in a movable state, please lock the flowmeter.
Tighten the two knobs on the fastener by hand, as long as the device does not rotate and move.
Finished
The torque value of the knob should be between 0.20 N-m (2kgf-cm) and 0.35 N-m (3.5kgf-cm), and should not exceed 0.4 N-m (4.0kgf-cm), which will damage or shorten the life of the flowmeter.
Please turn off the device and unplug it before disassembling.
Take off the four hex socket head cap screws on the top housing according to the above image.
Separate the top and bottom housing.
Be aware when separating the top and bottom housing because there are many wires connecting both.
Rotate top housing to a desired viewing orientation.
Do not rotate the top housing too many times to prevent the cables from being damaged from unnecessary pulls.
On the bottom housing there is an O-ring with an inner groove for a thread hole . For it to work properly, please confirm there is no particle, fiber or any object that may break the sealing function before attaching the top and bottom housing.
Combine top with bottom housing.
Tighten four screws on top housing.
Too much torque may damage the device.
Finish.
After the mechanism is installed, execute Z03 to automatically initialize the flowmeter parameters, and the machine can work normally.
If there is still large flow data with the fluid stationary, execute a Z04 Zero Offset correction with water in the pipe and the fluid stationary.
If there is a reference value for the flow rate, you can use the Z05 Scale Factor to multiply the flow rate data by a certain ratio to correct it to the correct value.
The Z02 automatic pipe size detection feature is designed to enhance user efficiency and accuracy. This section introduces its main functions and usage steps:
System Startup: On the main screen, open the system menu and navigate to the "(Z Quick Menu)" interface.
Settings Page: In the "(Z Quick Menu)" options interface, locate and select the "(Z02 Automatic Pipe Size Detection)" menu, then press enter.
Initiate Detection: Click the “Start Detection” button. The system will automatically begin the pipe size detection process.
Viewing Results: Once detection is complete, the screen will display detailed results. You can then return to the main screen.
Example Installation: For a pipe size CNS W15 PVCU, the system will display normal detection results if installed correctly.
(Left Image): If a matching pipe size is found, the screen will display the pipe size name.
(Right Image): If no matching pipe size is found, the system will default to a CNS W size specification.
The pipe size is not in the built-in options. Refer to the A02 list for different model pipe sizes. See the pipe size guide for further details.
Improper installation: Excessive or insufficient torque can cause inaccurate detection results.
Pipe deformation due to material, pressure, wall thickness, or temperature may lead to inconsistent detection results.
Ensure the pipe is properly installed to prevent detection errors.
Regularly calibrate the system to maintain detection accuracy.
There are 4 buttons on the device, the definition of each button will be displayed at the upper row on the LCD screen. Generally, the leftmost button stands for “Exit” or “Back to last page”. The middle 2 buttons are for users to review page by page, modify data, or switch options. The rightmost button stands for “Set” or “Confirm”. Previously mentioned definitions are only for general use. For some other usage scenarios, button definitions are modifiable for usability or error proof.
Pressing the button for an extended period will cause damage to the button. Please avoid excessive pressing.
Definition of each LCD backlight color:
Green: Real-time data, device is working normally.
Orange: Non real-time data display. Set-up page display.
Due to frequent data updates for real time flow volume, data on the LED screen will update first, then data on the LCD screen. Therefore, they may have about 0.1 seconds updated time difference. between both data sets.If there are not many digits in the data, please use the LED screen for the main data.
Maximum 5 displayed digits are provided on the LED screen. If data digits exceed more than 5 digits, “FFFFF” will be displayed on the LED screen (please refer to the image below). At this time, for reading complete data, you can try to modify the units or see the 2nd row data on the LCD screen to confirm exact flow volume.
When the flow direction is reversed and the data is a negative number, the 1st digit will be a minus sign with four remaining digits.
Connect the cable inside the box to the power supply and communication system. The unused color cables should be covered or protected to avoid electric leakage or short circuit.
Before removing the top housing of the device and wiring, the device should be powered off and the M12 8-pin cable should be removed.

It is generally recommended to use a 24awg twisted pair cable with grounded shielding. The RS485 network must be designed as one line with multiple drops, not as a star or ring topology.
When the connection is long, please use the terminal resistance on the master and the farthest end of the line. It is generally recommended to use a 120Ω terminating resistor. For the actual value, please refer to the wire specifications.
If the signal is unstable, please choose a point on the line to use a bias resistor.
The 8-core cable is shipped with the device, if used in RS485 communication, please trim the length, try to use a short wire to reduce noise interference. Connect the shielding net to the main communication wire shielding and then ground it.
When there is a lot of signal interference, the software may need to do multiple inquiries to get a valid response.
Due to space constraints, the sticker on the side of the device only uses cable contact definitions.
The number of the device contact and the cable contact is mirrored and symmetrical.

Set-up steps as below:
Connect cable first according to the cable wiring instructions on this page.
Set up parameter E01 for selecting NC(Normal Close) or NO(Normal Open) when there is no signal.
Set up parameter E02 for specifying output signal content.
For selecting “pulse output”
Use E03 to confirm each pulse width.
Use F03 to simulate specific pulse output frequency at OCT for testing with external devices.
For selecting “pulse v2”
Use E03 to confirm each pulse width.
Use E14 to determine each pulse capacity.
F03 to simulate specific pulse output frequency at OCT for testing with external devices.
For selecting “out of range flow volume notice”.
Use D05 to turn on the alarm.
Use D06 D07 for specifying normal flow range.
Use D08 for specifying hysteresis range percentage. D07 is a positive value, it means the single range must exceed in order to disable the alarm.
Set up F01 and F02 to simulate flow volume and go back to the monitoring screen to confirm if the alarm works.
Turn off the simulation mode.
For selecting “Total Alarm.” (“Inform of over total target”)
Use D09 to turn off alarm.
Use D10 for specifying notification conditions. "Larger Than" is for positive flow direction, "Less Than" is for negative flow direction.
Use D11 for specifying total target, positive number is for positive flow, negative number is for negative flow.
Set up F01 and F02 to simulate flow volume and go back to the monitoring screen to confirm the alarm works.
Turn off the simulation mode.
Go back to the monitoring screen, finish.
The user uses parameter E13 to select a volume first, and the device outputs a digital square wave every time it accumulates through a specified volume.
For large numbers, writing and reading in different formats (float32/int64) may result in a discrepancy of less than 1/10,000. This command is limited to memory with a register length of 4. Please refer to the provided list.

Classification Option List Link
Links to detailed items under each category menu.
Purpose and Use Cases:
Certain Human-Machine Interfaces (HMIs) only support the
05 Write Command
to send a signal to reset the accumulated total. Additionally, some HMIs require support for the
01 Read Command
to verify that the sensor is functioning correctly.
This command does
not reset
the
C02.Del.Total
(Clear Accumulated Total) option. It only provides the HMI with the ability to read Single Bit data using the 01/05 commands. If the command format is correct, the flow meter will respond to the master device with a Bit read acknowledgment.

Set-up steps as below:
Connect cable according to the cable wiring instructions on this page.
This machine uses Modbus RTU protocol, communication parameter set-up as below:
Set E04 for Modbus ID , and please make sure there is no other device using the same address.
Set E05 for specifying communication Baud, this machine supports 9600, 19200, 38400 and 57600.
Please go back to the monitoring screen. RS485 only responses on monitoring screens.
If needed, please use F01 and F02 to set up the machine to do a communication test under simulation mode.
Turn off F02 simulation mode.
Finish.
This setting provides 4 options.
N.8.1
No parity bit with 1 stop bit
N.8.2
No parity bit with 2 stop bits
O.8.1
Odd parity bit with 1 stop bit.
E.8.1
Even parity bit with 1 stop bit
ST stands for start bit, D0 ~ D7 are data bits, SP stands for stop bit.
OP and EP stands for Odd-parity and Even-parity respectively
This option controls the direction of the transfer and selects LSB or MSB first.
LSB first is typically used for Modbus RTU.
The figure below presents the difference with N-8-1 mode.
This setting controls the byte order of multi-byte data. This setting solely interacts with the byte order of replied data. The byte format of register address and length in the commands still conform to the examples provided by manual. The figure below presents the byte order for when converting number 1000 in IEEE-754 format.
Example
The command below requests instantaneous flow speed (abbreviated to FS) and totalized flow rate ( abbreviated to TF) from the device.
The first line is the command sent by the master device. It is not affected by the current settings. Please refer to Modbus 04 command for details.
The second line is the response from the flow meter in Big Endian format. From left to right, 0x01 to 0x08 and CRC1 to CRC2 are not affected by the current settings. The order of the instantaneous flow rate (indicated as FS+number) and the accumulated flow rate (indicated as TF+number) in the response is also unaffected. Because it is set as Big Endian, the four bytes of the instantaneous flow rate (represented by FS3 to FS0) will be returned starting from FS3. The four bytes of the cumulative flow (represented by TF3 to TF0) will be returned starting from TF3.
The third line is the response from the flow meter in Little Endian format. From left to right, 0x01 to 0x08 and CRC1 to CRC2 are not affected by the current settings. The order of the instantaneous flow rate (indicated as FS+number) and the accumulated flow rate (indicated as TF+number) in the response is also unaffected. Because it is set as Little Endian, the four bytes of the instantaneous flow rate (represented by FS0 to FS3) will be returned starting from FS0. The four bytes of the cumulative flow (represented by TF0 to TF3) will be returned starting from TF0.
bit order: lsb first
byte order: big endian
Data bits:8
Parity: None
Stop bits: 1
Floating point number follows IEEE754-1985. The float32 below stands for 32bits Single precision floating point number.
Register: Length of 2 Byte or 16bit which is unit length of memory in Modbus RTU.
Byte: 8 bit length
Modbus memory is divided into two categories, read-only and read-write.
Read-only type is mainly for flow meter status related memory, such as instantaneous flow rate. This is also the most commonly used memory. Detail information in following page:
Read-write memory is mainly to set-up parameters such as pipe diameter, and to reset variables, such as set zero on the cumulative flow. Read-write memory is only readable by using instruction 03. You can only change one parameter at a time with the write operation. If the length of the target register is 1, please use instruction 06. If the length is 2 registers, please use instruction 30. Please see read-write memory detail page below:

A03 Options A03 offers two different units for inputting pipe dimension data:
Depending on the selection of A03 and the machine model, the input ranges for A04 ~ A07 will vary.
If A04 ~ A07 values are entered first and A03’s unit is subsequently changed, the machine will automatically perform unit conversion.
Example: If A04 (Outer Diameter) is entered as 1.0 in inch mode, and A03 is later switched to mm, the A04 value will automatically convert to 25.4 mm.
Input Range for A04 ~ A07 When A03 is in mm Mode Since the relationship is OD - 2 × thickness = ID, if any of the entered parameters cause one of these four parameters (OD, thickness, ID) to exceed the minimum or maximum limits, the data cannot be saved.
Input Range for A04 ~ A07 When A03 is in Inch Mode The same rule applies: OD - 2 × thickness = ID. If any entered parameter causes one of these four parameters to exceed the permissible range, saving will be restricted.
Defines the method for calculating the cumulative flow. Options include:
Positive Flow
Negative Flow
Net Flow
Changing this method will reset the cumulative flow data. Default setting: Positive Flow.
After selecting a command, confirm whether to Save or Not Save.
Clears the cumulative flow data. Selecting this option will reset all cumulative flow values to zero.

After selecting a command, confirm whether to Save or Not Save.
The simple calibration mode applies a formula to adjust the instantaneous flow rate:
Calibrated instantaneous flow = (K03 × uncalibrated instantaneous flow) − K04
Example 1 If the desired calibrated flow rate is half of the current displayed value, set K03 to 0.5, and leave K04 at the default value 0.
Example:
Uncalibrated instantaneous flow: 5.0 L/min
Calibrated instantaneous flow: 2.5 L/min = 0.5 × 5.0 L/min
Example 2 For multi-point calibration requiring the addition or subtraction of a constant to maintain linearity:
Set K03 to 0.5 and K04 to 1.0.
4 L/min = 0.5 × 10 L/min − 1.0
9 L/min = 0.5 × 20 L/min − 1.0
A proportional adjustment to the flow rate, default is 1.0. This parameter is synchronised with Z05.
A fixed value is subtracted from the instantaneous flow rate according to the input. The unit matches the system setting.
Example: Entering 1.0 subtracts 1.0 from the current flow. If the original flow is 3.0, the output becomes 2.0. Default value: 0.0. This parameter functions similarly to Zero Offset but operates independently.
Adjusts the ratio of the amount added to the Totalizer from the calibrated instantaneous flow. It does not affect previously accumulated data. Adjustments amplify both positive and negative values.
Use case: Maintain the same instantaneous flow data while accounting for differences in cumulative values (e.g., using density to reflect weight).
Default value: 1.0.
Formula:
New cumulative value = Previous cumulative value + (K05 × newly added calibrated flow)
Example: If the Totalizer currently increases by 1 L/min, and the cumulative value is 100 L, to double the accumulation rate without altering the flow rate, set K05 to 2.0:
New cumulative value = 100 + 2 × 1 = 102 L

Environment and Parameter Check
Confirm that the device power supply is normal.
Confirm whether the confirmation page data is consistent with the communication data.
All unused wires are insulated, and there is no magnetic field interference in the surrounding area.
Hardware, Wiring, and Program of the Receiver Check
Confirm whether the RS485 command is used correctly.
Only one flowmeter is connected to the line, whether it can communicate normally.
Make sure the RS485 wiring is using the series connection method and not the star connection method.
In the case of multiple devices, is there any phenomenon that the power supply and ground wire of some devices are different, resulting in ground looping and potential fluctuation?
Does the line meet the requirements for twisted wire, thickness, series connection, and short fork?
For longer lines, do you use terminating resistors at both ends of the circuit?
For scenarios with large external interference, is a bias circuit used?
If there are multiple devices on the line, have you confirmed that the Baud of each device is the same and the ID is different?
Use an oscilloscope to see if the noise between the RS485 +/- lines is too high? (>200 mVpp generally considered too large)
Use a computer or a similar platform with high development flexibility to connect to a single flowmeter, first confirm that all communication settings and commands can communicate normally. Then modify the controller program.
Results and Actions
The RS485 output is normal, and the receiver equipment and programs are also normal. If the data is still abnormal, confirm other abnormal causes (pipe size, flow rate).
The main unit of this device may be damaged. If you have other units at hand, you can conduct a cross test to confirm that the receiving device, data processing program or line are all normal.
Please contact the original factory after recording the serial number of the fuselage, the wiring diagram (all flowmeter-related wiring) and the model brand of the receiving end.
If the line or environment cannot be improved, please allow the program to allow more re-communication attempts.
