Apr 20, 2015 · Measurement of boiler steam drum level using a differential pressure transmitter must take into account certain physical properties of the fluid. 1. The Steam drum contains a two-phase mixture of water and steam at saturation conditions. 2. The densities of water and steam vary with saturation temperature or pressure. 3.

Controlling Boiler Water Levels with a Differential

Mar 22, 2021 · One of the best ways to do this is with a differential pressure transducer. As its name implies, a differential pressure transducer has two ports for pressure measurement and calculates the difference between the readings. How Does a Differential Pressure Transducer Work? There is a working leg and a reference leg that get piped to the transmitter. The working leg is piped to the positive port and the reference leg is piped to the negative
