SERIES 160

DWYER SERIES 160 STAINLESS STEEL PILOT TUBE | ACCURATE AIR VELOCITY MEASUREMENT

A durable 304 stainless steel pitot tube designed for accurate air velocity measurements in HVAC and industrial ductwork.

  • Low sensitivity to misalignment up to 15 degrees
  • No calibration needed due to ASHRAE tip design
  • Silver soldered connections for leak-proof operation
  • 5/16″ models rated to 1500°F (815.5°C)

DWYER SERIES 160 STAINLESS STEEL PILOT TUBE | ACCURATE AIR VELOCITY MEASUREMENT

The Series 160 Pitot Tube is constructed from corrosion-resistant 304 stainless steel and features permanently etched insertion depth graduations for long-term service. It utilizes an ASME design that meets AMCA and ASHRAE specifications, ensuring maximum accuracy without the need for manual calibration. Its hemispherical tip design provides low sensitivity to misalignment, allowing for accurate readings even if the tube is misaligned by up to 15 degrees.

PRODUCT USES:

  • Monitoring and controlling air velocity or flow in HVAC systems.
  • Performing duct traverses for environmental testing.
  • Measuring static pressure, vacuum, or differential pressure in air and compatible gas streams.
  • Industrial air balancing and laboratory-grade flow measurements.
