The Waddell HVAC Transmitter will read, display, and output selectable air flow or velocity and air stream temperatures.
The internal components include a high-accuracy differential pressure transmitter, a microcontroller, display for flow / velocity and temperature, and terminals for voltage output to a BMS.
A temperature probe is included for a field selectable location and wiring to the enclosure. The output signal from the pressure transmitter is sent to the on-board computer for square root extraction, which outputs a signal linear to flow or velocity.
An auto zero switch is included to confirm transmitter calibration.
