DPT-Flow is a flow transmitter that provides a new and easy way to measure the flow rate on centrifugal fans.
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. The device is supplied with an optional FloXactTM averaging measurement probe.
Usage
The DPT-Flow is designed for air handling units to measure the air flow on centrifugal fans. The DPT-Flow can be used as an on-site display for flow or as a transmitter to regulate the air flow on a selected fan or blower.
The DPT-Flow can also be used in the duct system or in air handling units as an on-site display for flow or as a transmitter to regulate the air flow in a duct. 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.
