Series PAFS-1000 Averaging Flow Sensor
Description: The Series PAFS-1000 Averaging Flow Sensor by Dwyer Instruments, Inc. is specifically engineered for sensing differential pressure in the inlet section of variable air volume terminal units and fan terminal units. These sensors can also be utilized to sense differential pressure at various locations within the main or branch duct systems. Featuring "H" and "L" ports to sense total pressure and static pressure respectively, the differential between these signals yields velocity pressure. With models offering up to ten sensing points and lengths ranging from 3-5/32˝ to 23-29/32˝ (8.02 to 60.72 cm), the PAFS-1000 series accommodates box sizes from 4˝ to 30˝ (10.16 to 76.20 cm), ensuring versatility and accuracy in air flow monitoring applications.
