User-friendly on-site display for air flow designed for environments and applications where electricity is not available.
One device is suitable for a range of different fan types. It also provides an easy way to measure flow rate in a duct system for example together with a FloXactTM averaging measurement probe.


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

The DPT-Flow-Batt can also be used in the duct system as an on-site display for flow. The device can be used with several different measurement probes such as FloXactTM or pitot tube, and air dampers. The requirement is that the K-value of the measurement probe or damper is known.
