Differential pressure (DP) is a common and well-understood technology for measuring the flow of process fluids for several reasons: Versatility: It can measure virtually any type of fluid: liquid, gas ...

The transmitters come in piston and diaphragm-sensor models with ratings of 1,500 to 5,000-psig line pressures. DP ranges are 0-5 to 0-1,000 psid for the piston version and 0-5 to 0-300 psid for the ...

This article describes how a multivariable pressure transmitter with built-in dynamic compensation can correct for many of the errors and inaccuracies that can occur in differential pressure based ...
