AIR FLOW AND VELOCITY TRANSMITTERS - AVT Series

Multifunctional air velocity transmitters for building automation systems

The AVT series air velocity transmitters are engineered for building automation in the HVAC/R industry. The AVTs measure air velocity and temperature, with field selectable range and output options in a single device. Designed with a duct mount probe and adjustable collar suitable for round or rectangular ducts.

AVT series devices include:
• 3 field selectable measurement ranges for air velocity, selectable via jumper (see Model Summary)
• Separate readings and outputs for air velocity and temperature. • Proportional output options include: voltage (0–10 V) and current (4–20 mA)

AVT series device options offer:
• Backlit display
• Field adjustable relay

AVT series devices are commonly used in HVAC/R systems for:
• in-duct air flow and velocity monitoring
• in-duct temperature monitoring
• VAV applications

AIR FLOW AND VELOCITY TRANSMITTERS DPT-FLOW

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:
o Measure and monitor in-duct volume flow, velocity or differential pressure
o Measure and monitor air flow across centrifugal fans

• Multiple field selectable measurement units:
o Volume flow: m3/s, m3/h, cfm, l/s o Velocity: m/s, ft/min
o Pressure: Pa, inWC, mmWC, kPa, mbar, psi

• Unique proportional output options:
o Volume flow or velocity: voltage (0–10 V) or current (4–20 mA) 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, eliminating the need for periodic manual autozeroing to ensure long term accuracy
