Air flow sensors and air flow meters - Product overview

Air flow sensors and volume flow meters are suitable for measuring and controlling volume flows in ventilation and air conditioning systems. Volume flow sensors measure the total pressure, the static pressure of the air flow and the average air velocity. Even very low air velocities of up to 1.0 m/s can be measured by a special shape of the sensor.Get price
