Pressure sensors, transducers and transmitters are stationary pressure gauges designed to continuously monitor atmospheric pressure, gas pressure, or differential pressure by comparing two simultaneous pressure measurements. Very often in the field of ventilation, the pressure measurement of manometers is exploited to measure the flow rate and velocity of an air stream, using a Pitot tube or a DEBIMO wing.
