Measure principle

LORRIC’s paddlewheel flow meter with it’s Axlesense technology can detect paddle rotation as short as 3 degrees. In addition, Axlesense technology enables the flowmeter to provide accurate measurement results even under 0.3 m/s flow speeds with a faster response time. Also, our flowmeter has the best in class linearity of 0.5% FS.

In addition to a faster response, LORRIC’s Axlesense technology allows for bi-directional measurement. The flows’ direction can be determined by the positive and negative signs.

The measurement method of LORRIC’s paddle wheel flowmeter is magnetism and paddle’s rotation. The solid foreign matters, magnetic substance, crystalloid, and water hammer should be avoided. Meanwhile, there should not be any interference by strong magnetic fields around the flowmeter.

Solid foreign matters, magnetic substance, crystalloid, and water hammer may cause paddle wheel stuck and shorten its life. Another feature of AxleSense technology is providing an alarm when paddle wheel is damaged or lost by external force or abrasion.

Please remove anything with a strong magnetic field around the paddle wheel flowmeter which may cause incorrect flow volume measurement or no rotation of the paddle wheel.

Usage scenario

LORRIC paddle wheel flowmeter is designed to measure flow volume of liquid without large amounts of impurities in the pipe filled with liquid under an industrial environment. Installation location should be chosen at where liquid in pipe could be stable and fully developed, and the liquid temperature should be between 0 to 50°C(due to the limitation of PVC pipe and paddle base). The device of paddle wheel flowmeter provides water resistant (waterproof level: IP65) but not for under water usage. Material of device housing is PC which provides a bit of chemical resistance but cannot be exposed to a large amount of chemical for a long time.

Following factors should be considered for choosing paddle wheel flowmeter and T-connector :

1. Temperature resistance

2. Chemical resistance

3. Pressure resistance

Matters that need attention before installing!!

If any of the scenarios below occur and damage the paddlewheel, the warranty is void.

• If the device material is PC then it is not resistant to PVC glue with its strong gas and lubricant for PVC pipe. Therefore, before installing the paddlewheel flowmeter you must be sure the glue is dry between the connecting pipe and adapter.

• EPDM seal material only works with certain chemicals, but not oil.

• Please notice if chemicals are flowing vertically it could potentially damage the paddle wheel flowmeter.

• If the paddle wheel flowmeter is not able to be aligned with the main pipe or is taken as supported point on the pipeline, the flowmeter may bear unexpected force which could shorten usage life and cause water leakage.

• During the installation, it is better to use hands to lock the union nuts until there is no water leakage instead of using tools which could damage the flowmeter.

• Inaccurate piping may cause liquid leakage and lead to the paddle wheel flowmeter’s damage.

• When valving, water hammer should be carefully avoided to prevent paddle wheel flowmeter damage.

• The operational device of the paddle wheel flowmeter is not UV resistant. Therefore, we suggest to cover it with protector if installed outdoors.

• The seller will not be responsible of free maintenance for any defect or malfunction incurred by individual causes.

• If the paddlewheel flowmeter is transported with it's piping system to another site without protection it could be damaged.

• When installing the paddle wheel flowmeter there should be an appropriate amount of spacing for union and flange installation. If not, the following accidents may occur:

  1. Crack on union nut

  2. Crack on adaptor

  3. Stripped T-connector thread

  4. Water leakage due to insufficient compression or missing sealing

• Within correct installation, the paddle wheel flowmeter can resist maximum pressure up to 10 kg/cm². Do not use too much torque to lock the union nuts, otherwise the following accidents could occur :

  1. Crack on union nut

  2. Crack on adaptor

  3. Stripped T-connector thread.

  4. Sealing failure due to excessive compression.

How to choose an installation location

The 1st principle for choosing an installation location where the pipe is filled with liquid to avoid issues caused by air bubble 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 flow volume measurement of LORRIC’s paddle wheel flowmeter is based on the rotating mechanism of the paddle wheel. Paddle or axel could be lost under long-term abrasion or impact by external forces.Users should pay careful attention to any equipment that may cause the above damage.

The LCD display screen should not be exposed to direct sunlight that could cause visibility issues and a shorter usage life. Therefore, installing the flowmeter under direct sunlight should be avoided or with a sunlight protector is recommended.

There should be at least 10D (10x the inside diameter of the pipe) of straight pipe in front of the flowmeter and 5D of straight pipe behind the flowmeter to stabilize flow.

During flow movement, where the liquid is coming from means the front and where it’s moving to means the back. Generally, it is recommended that the flowmeter be installed at a position 10D (10x inside diameter of the pipe) at the front and 5D at the back (as shown in the figure below). If the inside of the pipe diameter is unknown, the outside of the diameter can be used.

Install the paddlewheel flowmeter before the valve.

The flow meter should be installed upstream of valve, so the fluid will be fully developed. This recommendation is also applicable to other piping components that may affect the flow field.

Vertical pipe

Please choose the vertical pipe with an bottom-up flow direction.

Horizontal pipe

• Please choose the location with full liquid, like the lower part of the inclined pipe.

• LORRIC’s paddlewheel flowmeter should not be installed at the top right or bottom side of the pipe in order to avoid the interruption of air bubbles or precipitate.

• If the paddle wheel flowmeter is installed on the side, which also affects flow measurement and causes a shorter product life.

Please notice the air bubble in the pipe to avoid measurement error. If the location of installation for the paddlewheel is close to a tank where pressure is low. We recommend installing a valve at the pipe exit to avoid generating any air bubbles.

Installation steps for brand-new products

1. Take off union adapter and nuts, paddle set, and device from T-connector

2. Install union adapter and nuts with pipe: Install the union adapter and nuts to the pipe with glue. Before going to the next step, the glue should be completely dry.

3. Lock T-connector and pipe with union adapter

4. Install paddle set and seals with T-connector: The arrow sign on the top of the paddle set means the direction of flow, the top side of the arrow sign means the direction of line-out. As below image, please refer to it before installation.

5. Install device to the paddle base and rotate it clockwise to the end. With deterioration design, please watch the installation direction and do not force it.

6. Fix device with paddle base through the side of it: The screws for fixing the device with the paddle set are not leakproof. Please avoid excessive force when screwing in the device which may cause damage.

Notices before installing

Confirm the version of the instruction manual, hardware, and firmware.

• Make sure that the installation environment meets the standard for flow volume monitoring. There should be a certain distance in front and after the location of the installed flowmeter. The proper position for the flowmeter should be face up horizontally or vertically depending on the flow direction.

• Confirm temperature and chemical resistance, and the size of pipes.

• Ingredients in chemicals and operating temperatures will differ according to industry. Before purchasing the flowmeter, please confirm these specifications to avoid any damage to the flowmeter.

• Please avoid measuring fluids with magnetic particles which may cause LORRIC’s paddle wheel flowmeter to work improperly. The reason being, is the paddlewheel uses magnetic flow sensor technology. In addition, we suggest placing it at a distance from equipment which may generate a strong magnetic field, like motors and electromagnetic valves.

Instantaneous flow volume and deviation

The maximum possible deviation for LORRIC’s paddle wheel flow meter is 0.5 % F.S. + 2.5 % O.R. which could be converted to the relation of maximum possible deviation and displayed data under different flow speed as seen below.

Flow speed

The data displayed on the screen is the flow speed in the T-connector. In most cases it will be a bit faster than the flow speed of same ordinary pipe at the same flow volume.

Cumulative flow speed and historical data.

Flow volume will be accumulated continuously until it is manually zeroed.

Maximum cumulative flow volume is 999,999,999 Litre and will be zeroed until it is exceeded.

Parameter C1 affects historical data and flow direction. Historical date data is set by classification G of the parameter.​

Calculation of historical flow volume is based on the following rules.

1. If cumulative flow volume is not zeroed on a certain day (ex. 2020/01/01), then the data on that day is the data at 23:59:59 minus the data at 23:59:59 on the previous day.

2. If cumulative flow volume is zeroed on a certain day, then data on that day is the data by 23:59:59.

Date data of historical flow volume is based on the following rules.

1. Recorded data will not be changed. Therefore, artificially setting a data recording date earlier than the previous one makes recorded data being the same or earlier between new and previous date.

​

The monitoring screen is composed of 2 sections. The first 7 pages are real-time data monitoring. The last 15 pages are the current date, time and historical cumulative volume for the past 14 days.

Pulse output

Pulse output is based on the frequency of the paddle wheel’s revolutions. A pulse will be sent by every 180° revolution. At a flow rate of 10m/s, the maximum frequency will not exceed 300 Hz. Since the data processing technology of LORRIC is not used, it is recommended to use it in an environment with lower accuracy requirements. To calculate the total flow volumes for a certain period of time, count the number of pulse signals received then divided by the corresponding proportion this manual provides. Proportion is defined by pipe size and material. Please refer to the following information.

Plastic (PVC, PP, PVDF) T-connector

PulseV2

PulseV2 is an exclusive function developed by LORRIC based on patented AxelSense technology. The unique algorithm allows the users to select a fixed volume, and the device will output a pulse every time a unit volume flows. The device can also intelligently correct error at low flow rate, making smaller pulse data error. Compared with the traditional pulse output, which directly outputs the revolutions of paddle wheel, every time the blade sweeps over the Sensor and outputs a pulse. “PulseV2” has two advantages: 1. The user can easily understand how to set up the controller. 2. Error of low flow rate is smaller.

The product obtained FCC/CE certification.

The product obtained RoHS certification.

Environment and Parameter Check

1. Confirm that the device power supply is normal.

2. Confirm whether the confirmation page data is consistent with the communication data.

3. Confirm that the RS485 function is enabled, the ID and Baud are defined correctly (parameters ).

4. All unused wires are insulated, and there is no magnetic field interference in the surrounding area.

Hardware, Wiring, and Program of the Receiver Check

1. Confirm whether the RS485 command is used correctly.

2. Only one flowmeter is connected to the line, whether it can communicate normally.

3. Make sure the RS485 wiring is using the series connection method and not the star connection method.

4. 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?

5. Does the line meet the requirements for twisted wire, thickness, series connection, and short fork?

6. For longer lines, do you use terminating resistors at both ends of the circuit?

7. For scenarios with large external interference, is a bias circuit used?

8. 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?

9. Use an oscilloscope to see if the noise between the RS485 +/- lines is too high? (>200 mVpp generally considered too large)

Results and Actions

1. 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, paddle wheel).

2. 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.

3. 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.

4. If the line or environment cannot be improved, please allow the program to allow more re-communication attempts.
