DPT-Flow-MOD Air Flow Transmitter
Produal DPT-Flow-MOD
The DPT-Flow range of flow transmitters is designed for building automation in the HVAC/Refrigeration market. These are the most technologically advanced transmitters on the market, measuring flow rate, velocity, and static or differential pressure.
The transmitters can be connected directly to the pressure measurement points of a centrifugal fan, providing accurate flow rate measurement. The user interface allows for easy selection of settings based on the selected fan or measuring probe.
