FLOW
Wedge-meter

DESCRIPTION: There are many types of geometries through which different fluids are drawn to generate a pressure differential. The most common geometry is circular. Others include the annular or the wedge or segmental type. In these latter geometries the flow lines are not concentric but are forced out of the equipment.
The incoming velocity profile will therefore have an effect on the pressure differential produced and the resulting Reynolds number discharge coefficient. The new designs of differential pressure transmitters, increasingly precise and capable of integrating a greater number of process variables, confirm the validity of this type of meter.
