CPA
Flow Nozzle
The CPA Flow Nozzle is the simplest differential pressure (dP) nozzle design offered by Canada Pipeline Accessories. It features only a converging inlet and a cylindrical throat, making it a low-maintenance, low-fouling solution for subsonic flow measurement.
Variations include long radius, ISA 1932, and cylindrical inlet designs. Pressure taps are installed on the meter run piping, with guidelines provided by CPA. The Flow Nozzle is custom-engineered to ISO 5167, ASME 3M, or ASME PTC-6 standards for your exact process conditions.
