Installation location of ultrasonic flowmeter

The selection of the installation pipe section has a great influence on the test accuracy. The selected pipe section should avoid interference and eddy currents, which have a greater impact on the measurement accuracy. Generally, the selection of the pipe section should meet the following conditions:

1. Avoid installing machines in water pumps, high-power radio stations, frequency conversion, that is, where there is strong magnetic field and vibration interference;

2. Choose a pipe section that should be uniform and dense and easy to ultrasonic transmission;

3. To have a long enough straight pipe section, the upstream straight pipe section of the installation point must be greater than 10D (note: D=diameter), and the downstream must be greater than 5D;

4. There should be a 30D distance upstream of the installation point from the pump;

5. The fluid should fill the pipeline;

6. There should be enough space around the pipeline to facilitate the operation of on-site personnel.
