Velocity Transmitter

Product Details:

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
