The use of vortex flowmeter is more and more extensive, and some problems will inevitably occur in the process of use, so to understand the matters to be paid attention to in the process of using vortex flowmeter.
1. vortex flowmeter should be independently grounded, if the grounding is poor, or the vibration of the pipeline is too large, thus introducing interference signals will produce no flow in the pipeline, the sensor has an output signal.
2. Before the vortex flowmeter is put into use, it must be ensured that the weld passage is clean, and there is no rust and welding slag to prevent damage to the instrument.
3. the vortex flow meter adjustment valve should be installed in the downstream of the flow meter, if the valve is installed in the upstream of the flow meter, the jet will be generated at a small flow rate, which will cause the deviation and stability of the flow value.
4. When there is a high-power motor or strong electric field near the vortex flowmeter, it is easier to cause errors, and there may be no medium flow in the pipeline, but the meter has a flow display.
