STAINLESS STEEL PITOT TUBE

ASME Design Meets AMCA and ASHRAE Codes

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.

FEATURES/BENEFITS

• 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)

APPLICATIONS

• Monitor or control air velocity or air flow when combined with differential pressure

gage, switch, or transmitter

Flange mounting plate 1/2˝ female NPT

Split flange mounting. Can be added to any Dwyer® No. 160

standard pitot tube. Zinc plated steel. Gasket is pattern for mounting

holes. Secure flange loosely to tube, adjust tube depth and tighten

screws. Gasket of 1/16˝ Neoprene fits tightly around tube and

against duct for leak-proof seal. Nuts, washers included.

Mounting gland. Versatile adaptor slips on any Series 160, 5/16˝

standard pitot tube made after Dec. 1990. Two-part stainless steel

fitting slides over tube and provides permanent, secure mounting.

Where duct interior is accessible, use the washers and jam nut

supplied. For blind applications or in thicker materials, use model

A-156 flange mounting plate. Once tube is adjusted to proper depth

and angle, tighten smaller hex bushing to lock position. Graphite

bushing inside assures leak-proof seal even at higher temperatures.

TFE bushing also available.

Note: For full insertion with this fitting,

order next longer pitot tube. A-159 mounting gland is used for both

duct mounting and flange mounting.

Carrying case for pitot tubes up to 48˝

Step drill. For fast, convenient installation of pitot tubes in sheet

metal ducts. No center punch needed; automatic de-burring. Drills

six sizes from 3/16˝-1/2˝ in 1/16˝ increments.
