Greenheck airflow measuring products are available with either differential pressure based technology or thermal dispersion technology.

Air flow measurement devices.

Differential pressure based airflow measuring products use an array of air pressure pick ups to compare the total pressure going through the airflow station with the static pressure in the station or pressure drop across a calibrated orifice fan inlet venturi. We offer a wide selection to meet your industry needs whether you re measuring airflow quality indoors or outdoors. Wireless measurement of pressure air velocity air flow temperature and humidity combine wireless gateway with various compatible probes and modules up to 50 foot range uhh2 includes mobile meter app to combine all readings into one device. The log linear method provides high accuracy 3 in flow totalization by measuring air flow closest the edges of the duct space preferentially.

Many of the requirements and limitations of one measurement technology however often are thought to apply to all. When selecting airflow measurement devices be knowledgeable of the many variables such as air velocity temperature humidity absolute pressure and dew point. Airflow measurement device selection is critical to the performance of today s state of the art hvac control systems as accuracy and repeatability can vary dramatically between instruments. At tsi precision measurement devices are our specialty and our line of air flow measurement instruments is unbeatable in terms of accuracy.
