Description
The Dwyer PAFS-1002 Averaging Flow Sensor is a precision-engineered pitot-style sensing element designed to provide accurate, repeatable airflow measurement in HVAC ducts, air handling units, and building automation systems. By sampling multiple pressure points across the duct cross-section and averaging the readings, this sensor delivers superior accuracy compared to single-point measurement devices — making it an ideal solution for demanding commercial and industrial airflow monitoring applications.
Product Overview
The PAFS-1002 is compatible with air and a wide range of non-corrosive compatible gases, making it a versatile choice for diverse HVAC and process applications. Its compact 3-5/32″ insertion length suits smaller duct installations where space is limited, while the 1/4″ I.D. and 3/8″ O.D. tubing process connections provide straightforward integration with standard pneumatic or electronic differential pressure transmitters.
