N OTE: All specifications stated in this manual may change without notice. 1.1 Unpack Unpack the Venturi Module WebA venturi meter is a way to measure flow in a pipe. The venturi is a section of pipe where the diameter is gradually reduced to some smaller area then gradually increased to the initial diameter To measure the flow in the pipe you measure the pressure at the inlet and then again at the narrowest section of the venturi. Assuming no friction.

WebSep 22, 2009 · INTRODUCTION. This meter uses a fascinating effect that occurs when gas flows at very high velocity through a nozzle. As the gas is sucked through the nozzle, the velocity increases as the cross-section of the nozzle passage decreases toward the throat. At the throat, the maximum achievable velocity is sonic – the speed of sound. WebA “sonic nozzle” (also known as “Critical Flow Venturi” or “Critical Flow Nozzle”) is a flow meter that can be used as a calibration standard for gas flow meters or any flow measurement device. By design, sonic nozzles are a constant volumetric flow meter. However, with the use of a regulated pressure supply, the sonic nozzle ...
