Description
DPT-Flow air flow transmitters are designed for building automation systems. These technologically advanced transmitters can measure volume flow, velocity, and static and differential pressure.
The transmitters can be connected directly to the pressure measurement points of a centrifugal fan, providing accurate flow measurement. The user interface enables easy selection of settings according to the selected fan or measurement probe.
The -AZ models include an automatic zeroing function, which zeroes the pressure measurement every 10 minutes. With automatic zeroing, the transmitter zero point is kept accurate by automatically eliminating the possible zero point drifting. The function also helps the device maintenance by removing the need of periodical manual zeroing by a service person.
