Ideal for sensing differential pressure in the inlet section of variable air volume terminal units and fan terminal units. Units can also be used to sense differential pressure at other locations in the main or branch duct systems. The "H" port senses total pressure and the "L" port senses static pressure.
Ideal for use with our precision manometers and air velocity gauges, these are constructed from corrosion resistant stainless steel for a lifetime of service. ASME design meets AMCA and ASHRAE specifications. Permanent, stamped insertion depth graduations on the sides facilitate accurate positioning.
Designed specifically for flow measurement of dirty, particulate laden air or gas streams. Large 5/16" dia. stainless steel tubing resists plugging under harsh, sooty conditions which quickly block conventional flow sensors. Total and static pressure tubes are precisely aligned and welded together every six inches.
