AIR FLOW

AIRFLOW AND VELOCITY TRANSMITTERS
DPT-FLOW
Multifunctional airflow transmitters for building automation systems
The DPT-Flow series airflow 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 devices can
be connected 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 settings according to the selected fan or in-duct measurement probe.
DPT-Flow series devices include:
• tTwo field selectable functions:
t o Measure and monitor in-duct volume flow, velocity or
t differential pressure
t o Measure and monitor airflow across centrifugal fans
• tMultiple field selectable measurement units:
t o Volume flow: m3/s, m3/h, cfm, l/s
t o Velocity: m/s, ft/min
t o Pressure: Pa, inWC, mmWC, kPa, mbar
• Unique proportional output options:
t o Volume flow or velocity: voltage (0–10 V) or current (4–20 mA)
t o Pressure: voltage (0–10 V) or current (4–20 mA)
DPT-Flow series device options offer:
• AZ (autozero) function for automatic zero point calibration,
t eliminating the need for periodic manual autozeroing
t to ensure long term accuracy
