Questions

Question

Are there any advantages to using a BACnet model other than the communications output?

Answer

When purchased with the BACnet communication option, the AVPT can display both the air velocity reading and temperature reading from a single device minimizing the need for an additional temperature sensor in the duct.

Question

The incorrect range was ordered in an AVPT; can I re-scale or calibrate this sensor in the field?

Answer

The AVPT models are calibrated to a specific range from the factory and cannot be re-ranged in the field.

Question

What is the maximum length that you can extend the wire leads?

Answer

The maxiumum cable length will vary depending on configuration and power supply; however, a 22 AWG shielded wire at 24V would provide suitable operation for most applications at a length of 328 feet (100 meters).

Question

Can the AVPT output volumetric flow readings

Answer

No, the AVPT is configured to output air velocity readings in FPM or M/S only. Consider looking at the AVUL for a unit able to output volumetric air flow.
