HART Protol Differential Smart Pressure Transducer For Flow Measurement

By measuring the difference in fluid pressure while the fluid flows through a pipe,it is possible to calculate the flow rate. For differential pressure flow measurement,a primary and secondary element are used. The primary element is designed to produce a difference in pressure as the flow increases.The most common being the orifice plate,venturi,flow nozzle,and pitot tube. The secondary element is the differential pressure transmitter.It is designed to measure the differential pressure produced by the primary element as accurately as possible.In particular,it is important that the differential pressure measurement is not affected by changes in the fluid line pressure,temperature or other properties such as ambient temperature.

A good DP transmitter will ensure that the differential pressure is measured accurately,regardless of other changing parameters and will reliably transmit signal to represent the differential pressure. In a typical control loop,the transmitter signal is fed to the controller where output is used to regulate the flow rate through a control valve.
