Requirement to the installation position of the Ultrasonic flow sensor

Requirement to the installation position of the Ultrasonic flow sensor

1> The installation position on pipeline must be full of fluid, the position marked with red in the following diagram are pipeline section of full fluid. The pipeline should not have strong vibration.

2> The installation position on pipeline must be steady flow section, see the positions marked with “√” in the following diagrams

The requirement of steady flow field as follow:

●If the installation position is far away from pump’s outlet and the half-open valve, make sure the upstream straight pipe length ≥10D, downstream straight pipe length ≥5D

●If the installation position is near the pump’s outlet or near the half-open valve, make sure the upstream straight pipe length ≥30D, downstream straight pipe length ≥5D

3> End user should select the installation position which is not easy to produce scale formation, if the pipeline cannot avoid the scale formation, user can set the thickness 

    of scale formation as the liner of pipeline.

4> At the same pipeline system, user should select the pipeline section of lower temperature as the installation position.

5> Ultrasonic flow converter should keep away from the strong electromagnetic interference source such as frequency converter, broadcasting station, base station, high-voltage power line. Do not share the power supply with the frequency converter, advise to use the isolated power supply. The shielding layer of flow converter, flow sensor should be ground connection.

6> For the flow meter which need to be buried under ground, need to build a instrument well, in order to make sure the instrument well has enough installation and maintaining space for the flow meter, the dimension of the instrument well should meet the requirement shown in the following diagram:
