A differential pressure transmitter is an instrument that can consistently and accurately create a pressure drop in a pipe and then use the pressure measurement on either side to provide the rate of flow within the pipe. A differential pressure flow transmitter can be easily installed in many applications.
Differential Pressure Transmitter Overview
Differential pressure transmitter is largely used in domestic and industrial applications. It is often the basis of other measurements such as flow, level, density, viscosity, and even temperature. The most common being level and flow.
DP Flow rate transmitter is one of the most common applications for differential pressure transmitters. By measuring the difference in fluid pressure while the fluid flows through a pipe it is possible to calculate the flow rate.
DP Transmitter Principle
The industrial differential pressure transmitters are made of two housings. The pressure sensing element is housed in the bottom half, and the electronics are housed in the top half. It will have two pressure ports marked as “High” and “Low”. It is not compulsory that the high port will be always at high pressure and the low port always at low pressure. This labeling has its relation to the effect of the port on the output signal.
Differential pressure-based level sensors can be easily mounted or retrofitted to the surface of the vessel.
To carry out maintenance and testing, these sensors can be provided with block valves for isolating them carefully from the process liquid.
They can be easily applied in level measurement applications such as total level in separator vessels where other level measurement devices are not feasible owing to the extensive changes in material formation experienced in the upper state.
