Multifunctional air flow transmitters for building automation systems:
The DPT-Flow series 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 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 are commonly used in HVAC/R systems for:

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

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 o
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

Technical details:

Accuracy (from applied pressure): (models 1000 and 2000)	Pressure < 125 Pa = 1 % + ±2 Pa Pressure > 125 Pa = 1 % + ±1 Pa
Accuracy (from applied pressure): (models 5000 and 7000)	Pressure < 125 Pa = 1.5 % + ±2 Pa Pressure > 125 Pa = 1.5 % + ±1 Pa
Zero point calibration:	automatic with autozero element (-AZ) or by pushbutton
Measuring units:	Pressure: Pa, kPa, mbar, inchWC, mmWC, psi Flow: m3/s, m3/hr, cfm, l/s, m/s, ft/min
