Sonic Nozzles

Cox Series 220 Sonic Nozzles are mass flow instruments designed for the accurate measurement and control of gas flow. The internal design of the nozzle consists of a circular arc that leads to the minimum throat area. Tangent to the circular arc on the exhaust side is a conical diffuser section. Common applications of the sonic nozzle include use as a calibration standard, gas flow meter, flow controller and flow limiting device.
