The DPT Flow is a universal Air Flow Sensor designed to be used with external measurement probes to measure air volume flow in ventilation and air condition system. The sensor measures air volume and velocity, displaying values in various optional units like cfm, m3h, l/s etc.
Due to its unique design, the FloXact™ probes used with the DPT-Flow-U Transmitter, amplify the differential pressure by approximately 2.5 times, achieving very accurate measurements of low air velocities down to 200 fpm. 

The AVT Air Velocity Sensors can be used in Ventilation and Air Conditioning systems.The sensors measure air velocity and temperature. Air Flow can be calculated by multiplying the velocity by the cross section of the duct. 

• Easy and quick installation
• Variety of velocity ranges in one sensor
• Option for local Display 
• Option of local Changeover contact relay
• Additional Temperature output
• Mounting in Rectangular and Round ducts
