About differential pressure flow measurement

Proven use in a wide range of applications across industries: Differential pressure transmitters offer the possibility of continuous flow measurement in conjunction with differential pressure transmitters in gases, vapors and liquids. These transmitters are suitable for all types of media, both in standard applications and applications with high process pressures and temperatures.

Measuring principle

Flow measurement is used to determine the quantity that flows through a pipe system per unit of time. The measurement of flow by means of differential pressure is carried out using differential pressure transducers. Differential pressure transducers include orifices, pitot tubes or Venturi tubes. When installed in the pipe, they generate a differential pressure which is measured using the differential pressure transmitter. The flow rate is calculated in the differential pressure transmitter from this measured value.

Benefits

  • Universal differential pressure transmitters for flow, level and filter applications
  • Pre-assembled pressure-tested valve blocks
