SECTION 1.0: General Information
1.1 TYPICAL THERMAL AIRFLOW MEASUREMENT SYSTEM INSTALLATION
Greenheck’s Vari-Green
®
system accurately measures the average velocity of flowing air by means of thermal
dispersion at the sensor locations in the duct. Temperature is also measured via these sensors. The Vari-Green
transmitter can receive up to 32 individual flow sensors measuring airflow in a single duct, and it generates the
outputs, including network and analog signals, which are conveyed to a local controller or BMS.
Physical installation details for the probe array or flow stations can be found in Greenheck’s Installation Instructions.
