PAFS-1000 Series Flow Sensor

Dwyer
Dwyer's new PAFS-1000 series of flow sensors is ideal for detecting differential pressure in the inlet section of variable air volume terminal units and fan terminal units. The units can be used to detect differential pressure elsewhere in the main duct or branching systems. The "H" port detects the total pressure and the "L" port detects the static pressure. The difference between these signals is differential or speed pressure. Up to four sensor tips and lengths from 8.02 to 25.62 cm (3-5/32" to 9-29/32") are available to accommodate case diameters from 10.16 to 40.64 cm (4" to 16") for PAFS-1002 to PAFS-1005 models. For PAFS-1006 to PAFS-1011 models, up to ten sensor tips and lengths from 31.75 to 60.72 cm (12-1/2" to 23-29/32") are available to accommodate the ducts according to the corresponding sizes.
