Product Principle

CH-LUB vortex flowmeter is mainly used for industrial pipeline media fluid flow measurement, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large range, high accuracy, in the measurement of the volume of flow conditions almost independent of the fluid density, pressure, temperature, viscosity and other parameters. There are no moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stabilized for a long time. Vortex flowmeter using piezoelectric stress sensor, high reliability, can be in -20 ℃ ~ +250 ℃ working temperature range. There are analog standard signals, but also digital pulse signal output, easy to use with computers and other digital systems, is a more advanced, ideal flow meter.

Installation Diagram

caveat

legend (of a map, etc)

1、Expand the installation of the pipe

For small diameter and large flow, must expand the installation of the pipe, while ensuring that the flow meter before the straight section ≥ 15D, after the straight section ≥ 5D

2、Shrinking pipe installation

For large caliber small flow, must be reduced installation, while ensuring that the flowmeter before the straight section ≥ 15D, after the straight section ≥ 5D

3、The installation of elbow

If the front end of the flowmeter has 90 ° elbow or T-type connector, to ensure that the flowmeter before the straight section ≥ 15D, after the straight section ≥ 5D

4, the same plane two elbow installation

If the front of the flowmeter has two 90 ° elbow, to ensure that the flowmeter before the straight section ≥ 20D, after the straight section ≥ 5D

5, the installation of two elbows in different planes

If the front of the flowmeter has two 90 ° elbow, to ensure that the flowmeter before the straight section ≥ 25D, after the straight section ≥ 5D

6、Installation of adjustment valve

If the flowmeter before and after the need to install control valves, to ensure that the flowmeter before the straight section ≥ 25D, after the straight section ≥ 5D
