Primary Elements for DP Flow

Primary Flow Element DP FlowWhat is a Primary Flow Element?

In differential pressure (DP) flow measurement, the primary element is what generates the differential pressure in the fluid. Primary elements are crucial to obtaining accurate, stable flow measurements.


  • Accelabar

    The Accelabar’s flow nozzle is specifically designed to accelerate, condition, and linearize the velocity profile for Verabar averaging pitot to measure the differential pressure accurately.
