DPT-Flow-Batt
Multifunctional air flow transmitters for
building automation systems
DPT-Flow Series-4 air flow transmitters are engineered for building automation in the HVAC/R industry. The most technologically advanced transmitters on the market, measuring volume flow, velocity, and static and differential pressure.
The DPT-Flow Series-4 devices can connect directly to the pressure measurement points in a centrifugal fan, providing accurate flow measurement of the fan. The smart user interface enables easy selection of configuration settings according to the
selected fan or in-duct measurement probe.
DPT-Flow Series-4 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
- Measure and monitor in-duct volume flow, velocity or
- Multiple field selectable measurement units:
- Volume flow: m3/s, m3/h, CFM, l/s
- Velocity: m/s, FPM
- Pressure: inWC, mmWC, Pa, kPa, mbar
- 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-4 device options include:
• The function for true automatic zero point calibration, eliminating the need for periodic manual pushbutton autozero to ensure long term accuracy.
• NIST-calibration documentation
