Mechanism Installation
Extremely important precautions to take note before installing!!
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.
How to Choose an Installation Location
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.
Vertical pipe
Please choose the vertical pipe with a bottom-up flow direction.
Horizontal pipe
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.
Please be cautious of the air bubble in the pipe to avoid measurement error.
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.
New Product Installation Process
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.
How to rotate the display screen direction
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.
