1. Installation Steps
Area flowmeters are widely used in industrial production due to their simple structure and convenient installation. This article will introduce the installation methods of area flowmeters and the precautions during installation.
Step 1
Install the area flow meter on a horizontal straight pipe, ensuring sufficient straight lengths upstream and downstream. The meter's installation direction should align with the fluid flow.

Step 2
Detach the end connectors from the flow meter body and inspect the meter for any damage.

Step 3
Install connectors and nuts according to different specifications, ensuring the presence of an O-ring to prevent leaks.
Threaded fittings
For threaded connections, use Teflon tape to enhance the seal with the main pipeline.
Insertio fittings
For insertion-type fittings, apply adhesive on both the interior of the fitting and the exterior of the pipe before bonding.
Step 4
Wait for the PVC adhesive to dry completely and its fumes to evaporate before hand-tightening the nuts onto the flow meter body.
2. Special Notices
1. Certain flowmeters contain magnetic materials – ensure that these fit your needs.
2. The following tips are advised in order to prevent damaging the flowmeter and void its warranty：
● The PC body can only tolerate clean tap water without any chemicals, cleaning detergents or other solvents.
● Both PC and PSU materials cannot tolerate organic compounds which might damage the flowmeter.
● Before making a purchase, validate that the flowmeter’s various parts are suitable for your purposes regarding factors such as operating temperatures, as every industry has different requirements
● The flowmeter’s body materials, PC and PSU, both cannot tolerate the following substances：
- PVC glue and the fumes it emits, and PVC lubricants (oils or ointments).
- Therefore, since the adaptor was glued to the main pipe using a PVC lubricant, the flowmeter body can only be installed after the PVC lubricant is completely dry.
● Flowmeters must be installed perpendicularly to the ground to ensure proper accuracy. Misalignment may cause the O-ring seals to leak and thus reduce the flowmeter’s lifetime.
● Tighten the union nuts only using your bare hands, and refrain from using tools. Installation using inappropriate tools may cause the union nuts, adaptors, thread or seal to break.
● Flowmeters cannot be used to support pipeline, so please make sure the main pipe is installed firmly.
● Incorrect pipe installation may cause leakage and damage to the flowmeter.
● Water hammers might also damage flowmeters.
● UV radiation might damage the meter body, so please use a UV-resistant cover for the flowmeter when flowmeters are installed outdoors.
● Voluntarily dismantling or modifying the unit might cause damage.
● The maximum recommended working pressure to avoid damage is 6kg/cm2.
3. Mismeasurement might arise from the following reasons：
● The liquid’s specific gravity differs from the flowmeter’s specific gravity.
● The liquid contains particles of suspended matter.
