The log linear method provides high accuracy 3 in flow totalization by measuring air flow closest the edges of the duct space preferentially.
Air flow measurement devices.
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.
We offer a wide selection to meet your industry needs whether you re measuring airflow quality indoors or outdoors.
Greenheck airflow measuring products are available with either differential pressure based technology or thermal dispersion technology.
Airflow instruments are accurate high quality professional grade instruments used by a wide range of customers including building service contractors commissioning specialists facility engineers and research professionals.
The grid lines which lay out the duct flow measurement points are traverses.
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.
