Differential Pressure Transmitter 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.

Details Images

The highest or middle part of the tank is the low pressure side [L] of the differential pressure transmitter, and the lowest part of the tank is the high pressure side [H];

Cable diameter φ8 ~ φ12.Signal terminals are located in a separate compartment of the electrical box. Unscrew the cover can be wiring. 

Differential pressure transmitter housing material is aluminum 14, the process connection is stainless steel, with IP66 / 67 protection rating.

Product Usage

Product other application

Differential pressure transmitters are commonly used to calculate pressure, flow, liquid level, volume, etc. in media. It is mainly used in industrial control fields such as energy, chemical, natural gas, power plants, paper making For example, in a milk manufacturing industry, the proportion of pipelines needs to be controlled, and a hygienic differential pressure transmitter is used to monitor the flow of the pipeline and control the proportion.
