1. Installation requirements and precautions for turbine flowmeter

The installation requirements and precautions for turbine flowmeter are as follows: The turbine flowmeter sensor should be installed in a location that is easy to maintain, has no vibration, strong magnetic interference, or thermal radiation in the pipeline. If installed outdoors, measures should be taken to avoid direct sunlight and rain. Installation requirements and precautions: For sensors installed horizontally, there should be no visible inclination in the pipeline, and the inclination angle should be within 5 °. The vertical deviation of the sensor pipeline installed vertically should be less than 5 °, and the fluid direction should be from bottom to top. The bypass and shut-off valves should be installed in places where the flow cannot be stopped, so that when maintenance or calibration of the flowmeter is needed, it does not affect the normal flow of the fluid. If the fluid contains impurities, a filter should be installed on the upstream side to prevent impurities from entering the turbine flowmeter and affecting its normal operation and measurement accuracy. If the fluid contains gas, a gas eliminator should be installed on the upstream side to avoid gas interference with the measurement results. At the same time, the discharge and exhaust ports of the filter and air purifier should be connected to safe places to prevent danger. The valve installation flow regulating valve should be installed downstream of the sensor, and the upstream shut-off valve should be fully opened during measurement, without vibration or leakage, so as not to affect the measurement results and the normal operation of the equipment. For processes that may gene

rate reverse flow, check valves should be added to prevent reverse fluid flow and protect the turbine flowmeter from damage. The installation position of the sensor should be concentric with the pipeline, and the sealing gasket should not protrude into the pipeline, otherwise it will affect the flow state of the granular material and cause measurement errors. Sensors should not be installed at the highest point of horizontal pipelines to prevent gas accumulation in the pipeline (such as air mixed in during flow stoppage) from staying at the sensor and being difficult to discharge, which may affect the measurement. The pipeline support and insulation sensor should be securely supported before and after the pipeline, without generating vibration, as vibration can affect the rotation of the turbine, thereby affecting measurement accuracy. For easily condensable fluids, insulation measures should be taken for the sensor and its front and rear pipelines to prevent fluid condensation from affecting the measurement. Transmission cables require shielded signal cables with double or three cores. Shielded signal cables are best grounded at the Chun end of the display instrument (flow accumulator or flow control instrument) to reduce the impact of external electromagnetic interference on the measurement signal. The transmission path should not be parallel to the power supply line, nor should it be laid in areas where the power supply line is concentrated, to avoid interference with signal transmission caused by the electromagnetic field generated by the power supply.
