PI300 Differential Pressure Transmitter

The primary element of Differential Pressure Transmitter is a special mechanical construction that introduces a pressure difference into the fluid flow. This can be a venturi tube, orifice plate, pitot tube, flow nozzle, or a laminar flow element. The primary element creates a pressure differential in the fluid flow by adding an artificial barrier using one of the mechanical barriers mentioned above. The secondary element picks up the pressures at two points, before and after the barrier.
