5 stands for water jets: Water projected by a nozzle (6.3 mm) against enclosure from any direction shall have no harmful effects.

** The flow velocity range may be slightly different due to factors such as piping diameter and fluid coefficient.

*** The device is calibrated with normal temperature water. Fluids with different viscosities may have different results, and may also change the minimum and maximum flow velocity.

Notices before installing

Confirm the version of the instruction manual, hardware, and firmware. Go to version page to check.

• 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.

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 noticed 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

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.

LCD screen displays 3 rows of information.

Function of each button

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 use scenarios, button definitions are modifiable for usability or error proof.

3. Orange: Non real-time data display. Historical data query and set-up page display.

Frequency of data update

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.

Displayed digits on LED screen

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 below image). 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 negative number, the 1st digit will be a minus sign with four remaining digits.
