Differential Pressure flow meters measure the velocity of fluids by reading the pressure loss across a pipe constriction. These meters can contain laminar plates, an orifice, nozzle, or Venturi tube to create an artificial constriction. Highly sensitive pressure sensors measure the pressure before and after the constriction. According to Bernoulli's principle, the pressure drop across the constriction is proportional to the square of the flow rate. The higher the pressure drop, the higher the flow rate.
Differential pressure flow meters utilize a robust, time proven measuring technique for a wide range of clean liquids and gases. The meters are available in a wide range of line sizes with wide temperature and pressure ranges. Installation is relatively easy and the meters often offer temperature and pressure measurements as well, measurements of mass flow compensation . Care should be taken with highly viscous liquids, though, as accuracy can be adversely affected or not achieved.
Selecting a Flow MeterThe basis of good flow meter selection is a clear understanding of the requirements of the particular application. Therefore, time should be invested in fully evaluating the nature of the process fluid and of the overall installation.
