This article describes how multivariable pressure transmitter with built-in dynamic compensation can correct many of the errors and inaccuracies that occur in differential pressure based flow measurements. It also explains how modern flowmeters can ensure ease of integration with FDT technology based tools.
Differential Pressure (DP) is defined as the difference between two pressures. Differential Pressure Transmitters use a reference point called the low-side pressure and compare it to the high-side pressure. Ports in the instrument are marked high-side and low-side.
