 What are the requirements for pipeline installation of liquid turbine flowmeters?

Turbine flowmeter pipeline installation matters: The sensor should be installed in a place where maintenance is easy, and the pipeline is free from vibration, strong electromagnetic interference and thermal radiation. The horizontal installation of the sensor requires that the pipeline should not have a visually observable inclination (usually within 5°), and the vertical deviation of the vertical installation of the sensor should be less than 5°. In places where the flow cannot be stopped, a bypass pipe and a reliable shut-off valve should be installed. When measuring, ensure that the bypass pipe does not leak. In the position where the sensor is installed in the newly laid pipeline, first connect a short pipe to replace the sensor. After the "line sweeping" work is completed, after confirming that the pipeline is cleaned, the sensor is officially connected. If the fluid contains impurities, a filter should be installed on the upstream side of the sensor, and the pipeline should be regularly cleaned to discharge precipitated impurities; if the measured liquid contains gas, an air eliminator should be installed on the upstream side of the sensor. The sewage outlet and air outlet of the filter and air eliminator should lead to a safe place. If the turbine flowmeter sensor is installed outdoors, measures should be taken to avoid direct sunlight and rain.
