What problems should Henan flowmeter manufacturers pay attention to when installing and using vortex flowmeters

What problems should Henan flowmeter manufacturers pay attention to when installing and using vortex flowmeters? Nowadays, many enterprises use vortex flowmeters when measuring flow. It is important to choose the appropriate model for this type of equipment, but also pay attention to The installation of the vortex flowmeter is required, so today I will talk about the details to be paid attention to when installing and using the vortex flowmeter. First, it may be necessary to disassemble the instrument when installing and debugging the vortex flowmeter, but pay attention to the pressure of the instrument, and it is not possible to disassemble the instrument under pressure, ensure that there is no pressure in the pipeline before disassembling, and eliminate the pressure. The method is to close the upstream valve and downstream valve and open the pressure relief device, at this time to ensure that there is no pressure in the pipeline. Second, because the pipelines that need to measure the flow are different, so when there is corrosive gas or toxic gas in the pipeline, attention should be paid to the protection work, and the vortex flowmeter should also be protected accordingly. When it is necessary to pay attention not to be charged, ensure that the vortex flowmeter is installed and then connected to the power supply for debugging. Third, because the negative end of the power supply of some vortex flowmeters is not grounded, in this case, do not turn on the power first after the wiring is completed, but check the insulation resistance of the negative end of the power supply and the ground. In this case, the insulation resistance is not required. less than 20MΩ. Fourth, when installing the vortex flowmeter, if the negative end of the power supply cannot be grounded, it should be an electronic instrument with its own power supply function when performing on-site testing, and the negative end of the instrument cannot be grounded. With a differential input, and the measurement is performed in the AC-coupled gear.
