Differential Pressure - Primary Flow Element

The flow element consists of a body and wedge flow restricton. This restriction creates a differential pressure in proportion to the square of the volumetric flow rate.The wedge restriction has no critical surface dimensions, or sharp edges, that will affect measurement accuracy as the result of normally expected wear. Matched with ABB Differential Pressure Transmitters, this flow meter provides a solution for most harsh applications.
