The Dwyer 160 Series stainless steel pitot tubes are  designed for use with differential pressure transmitters,  manometers, or air velocity gauges to measure air flow in  ducts. See Measuring Air Flow in the Technical Reference  Section for complete application information.

The 160 Series  is designed per ASME and meets AMCA and ASHRAE  standards. Insertion depth is stamped on the side of the pitot  tubes, and the static pressure port is parallel to the sensing  tube to allow easy alignment with air flow. A Model A-158 split  flange mounting kit allows for simple, leak-free mounting of  the 160 Series.

The SERIES 160 Stainless Steel Pitot Tube is constructed from corrosion resistant stainless steel with permanently etched insertion depth graduations for a lifetime of service. The static pressure port is parallel to the sensing tube to allow quick, easy alignment of the tube with air flow. A universal model fits the user supplied 3/4" schedule 40 pipe in any length.

Ideal for use with our precision manometers and air velocity gages, Dwyer® Pitot Tubes are constructed from corrosion resistant stainless steel for a lifetime of service. ASME design meets AMCA and ASHRAE specifications for maximum accuracy over a wide variety of flow conditions. No correction factors required as ASHRAE tip design yields a calibration factor of 1. ASHRAE design needs no calibration!

Permanent, stamped insertion depth graduations on sides of 160 series facilitate accurate positioning. Static pressure port is parallel to sensing tube allowing quick, easy alignment of tube with air flow. Low sensitivity to misalignment gives accurate reading even when tube is misaligned up to 15 degrees.

Various standard sizes are available for use in ducts as small as 4˝ dia, or as large as 36 ft dia. A universal model fits user supplied 3/4˝ schedule 40 (standard) pipe in any length. Several convenient mounting options are available for permanent installations.
