- Definition gas mass flowmeter consisting of a smooth rounded inlet section converging to a minimum throat area and then diverging along a pressure recovery section or exit cone Reference "COM-EN, based on:1) Trigas FI GmbH ""Sonic Nozzles"". http://www.trigasfi.de/pdf/Sonic-Nozzle-Brochure.pdf [18.3.2013] and2) Cox instruments > Gas flow Meters > Sonic Nozzle (Critical Flow Venturi). http://www.cox-instruments.com/gasflowmeters.html [18.3.2013]"
- Comment As a gas accelerates through the Nozzle, its velocity increases and its density decreases. The maximum velocity is achieved at the throat, the minimum area, where it reaches the desired speed of sound (Mach 1).
