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 FloXact^TM or pitot tube, and air dampers. The requirement is that the K-value of the measurement probe or damper is known.

DPT-Flow series devices include:

• Two field selectable functions:
• Measure and monitor in-duct volume flow, velocity or differential pressure
• Measure and monitor air flow across centrifugal fans

Multiple field selectable measurement units:

• Volume flow: m3/s, m3/h, cfm, l/s
• Velocity: m/s, ft/min
• Pressure: Pa, inWC, mmWC, kPa, mbar, psi

Unique proportional output options:

• Volume flow or velocity: voltage (0–10 V) or current (4–20 mA)
• Pressure: voltage (0–10 V) or current (4–20 mA)

DPT-Flow series device options offer:

• AZ (autozero) function for automatic zero point calibration, eliminating the need for periodic manual autozeroing to ensure long term accuracy

• Air flow monitoring across centrifugal fans and blowers
• In-duct temperature monitoring
• VAV applications

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 FloXactTMaveraging measurement probe.

Usage

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.
