Under normal circumstances, when the differential pressure transmitter measures the liquid level, the high pressure side is connected to the pressure pipe in the lower part of the container, and the low pressure side is connected to the pressure pipe in the upper part of the container. In this way, the output of the differential pressure transmitter can increase when the liquid level rises; The output decreases when the level drops, resulting in correct measurement results. Similarly, the differential pressure transmitter is also the same when measuring the flow rate, the positive pressure conduit is connected to the high-pressure side of the differential pressure transmitter, and the negative pressure conduit is connected to the low-pressure side of the differential pressure transmitter, so that the differential pressure transmitter can work normally. In the actual on-site installation process, due to improper operation and other reasons, the high and low pressure conduit is reversed, or in order to maintain and operate conveniently, the positive pressure conduit must be connected to the low-pressure side of the transmitter, and the negative pressure conduit must be connected to the high-pressure side of the transmitter. At this time, can the differential pressure transmitter still work normally? Does the pressure pipe need to be removed and reconnected? For differential pressure transmitters that measure hydrostatic liquid level, the pressure guide tube is reversed, and the output can only be displayed in reverse against convention. When the liquid level is lowest, the output is not zero, but 100%; When the liquid level is highest, the output is not the maximum, but O%, and this is how the differential pressure gauge with no zero migration in the early years was used. However, for differential pressure transmitters that measure flow, the pressure guide tube is connected backwards and usually does not work. The intelligent differential pressure transmitter can realize its function through the configuration of the handheld communicator, and there is a forward and reverse conversion module inside the differential pressure transmitter, as long as it is set to reverse, the problem of reverse connection of the pressure guide pipe can be solved. CYYZ3051 intelligent differential pressure transmitter, it can configure the instrument in real time during operation, such as modifying the range, monitoring variables, etc. CYYZ3051 intelligent differential pressure transmitter can be adjusted with its own range and zero button, or remotely adjust the positive and negative migration of the zero point with a HART handheld smart terminal.
