Pit 5: The signal line and power line go through the same pipe4-20mA,RS485, Weak electrical signals such as pulse signals are most afraid of strong electrical interference.If the signal line, frequency converter cable, high-power motor line, and power line are routed through the same conduit, the ...
Pit 4: The status of the drain valve and balance valve has not been confirmedDuring debugging, it is often necessary to open the drain valve, balance valve, and three valve group. But the most common problem on site is:After debugging, the valve status has not been restored.Result:Differential ...
Pit 3: Fluid accumulation, gas accumulation or imbalance of liquid columns on both sides of the pressure pipeWhen measuring steam differential pressure, if the pressure pipe is not handled properly, the data is easily distorted.Many sites have problems not with the instruments, but with the pressure ...
Pit 2: Inappropriate temperature measurement point locationMulti parameter flow transmitters typically require pressure and temperature to participate in compensation calculations. If the temperature point is too far away from the measurement location or installed in a location with significant ...
Pit 1: Insufficient front and rear straight pipe sectionsDifferential pressure flowmeter, vortex flowmeter and other instruments have requirements for flow field stability.If the flow meter is located in front of an elbow, valve, reducer, or tee, and the fluid has not yet stabilized before entering ...
