Dwyer 166-6 – Stainless Steel Pitot Tube, 1/8″ dia., 6″ Insertion Length, 3″ Tip

• No calibration needed.
• Precisely located, burr-free static pressure holes.
• Hemispherical tip design, best for accuracy if imperfectly aligned and nearly impossible to damage.
• Long lasting 304 stainless steel construction.
• Silver soldered connections for leak-proof operation.

The Dwyer 160 Series stainless steel pitot tubes are designed for use with differential pressure transmitters, manometers, or air velocity gauges to measure airflow 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 airflow. 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 airflow. A universal model fits the user-supplied 3/4″ schedule 40 pipes 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 are required as the 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. The static pressure port is parallel to the sensing tube, allowing quick, easy alignment of the tube with airflow. Low sensitivity to misalignment gives accurate reading even when the 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.
