APPLICATION
DPT-Flow airflow transmitters have been specially developed for applications in building automation. These advanced measuring instruments provide accurate measurements of volume flow, air velocity, static pressure and differential pressure. Thanks to the direct connection to the pressure measuring points of a centrifugal fan, they provide reliable flow measurements. The intuitive user interface makes setup easy, with the user easily selecting a fan or probe.
