This device is a versatile flow transmitter which is usable for a vast range of different fan types. It also provides an easy way to measure flow rate in a duct system. The device is supplied with an optional FloXactTM averaging measurement probe.


The DPT-Flow is designed for air handling units to measure the air flow on the centrifugal fans.

You can use DPT-FLOW with a local display to measure the flow or use as a transmitter to program and regulate the airflow on a specific blower or fan.

Another application of DPT-FLOW is in the duct system or air handling units. The type with display provides you the possibility to read the flow at the moment and locally. It can also be used as a transmitter to regulate the airflow in the duct.

DPT-FLOW can be combined with different measurement probes such as FloXactTM or pitot tube and air dampers. In this case, it is important to know the value of the K parameter for probe or damper.
