Installation requirements for sewage flow meters

1), environment selection

Try to stay away from equipment with strong electromagnetic fields, such as large motors, large transformers, large frequency converters, etc. The installation site should not have strong vibrations, the pipelines should be firmly fixed, and the ambient temperature should not change much (to prevent solid-liquid phase changes). The installation environment should be convenient for installation and maintenance.

2), location selection

The installation location must ensure that the pipe is always filled with the liquid to be measured.

Choose a place with small liquid flow pulses and stay away from local resistance parts such as pumps, valves, and elbows.

When measuring two-phase (solid, liquid and gas, liquid) liquids, you should choose a place that is not likely to cause phase separation.

The inner diameter or circumference of the pipe to be measured is easy to measure, and the ovality should be small.

3). Length of straight pipe section

The length of the straight pipe section on the upstream side of the pipeline where the sewage flow meter sensor is installed should be greater than or equal to 10D, and the length of the downstream side should not be less than 5D (D is the diameter of the pipe being measured).

4), flow control valve and regulating valve

The flow control valve should be installed in the measured pipe on the upstream side of the sensor, and the flow regulating valve should be installed on the downstream side of the sensor.

When the flow rate is high, usually the flow control valve should be in a fully open state.
