A &#;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.

The nozzles are designed and manufactured to the ISO standard and as such the gas is accelerated along the Bell Mouth converging section and then is expanded in a conical diverging section, which is designed for pressure recovery.
In the throat, or minimum area point of the Sonic Nozzle, the gas velocity becomes equal to the speed of sound. At this point, gas velocity and density are maximized, and the mass flow rate is now a function of the inlet pressure, inlet temperature, and the type of gas.
Gas Meter Test Bench
The "Calibration Standard" of the test bench serves as a primary calibration reference for testing and calibrating domestic gas meters, commonly utilized in establishments like hotels and restaurants. This device is particularly well-suited for Original Equipment Manufacturers (OEMs), Calibration Laboratories, and Calibration Service Providers.
Bell-Prover Gas Meter Test Bench:
Bell-Prover gas meter test benches are renowned for their high accuracy and reliability in calibrating gas meters. They utilize the bell-prover principle, where the displacement of a bell-shaped chamber filled with gas is precisely measured to determine flow rates. These test benches offer excellent accuracy, repeatability, and traceability, making them ideal for industries requiring stringent calibration standards such as utilities, natural gas distribution, and manufacturing.
