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.

• 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.
• ASME design meets AMCA and ASHRAE specification.
• Coefficient of "1."
• 5/16" models rated to 1500°F.
• Extended static connection helps guide tip within recommended 15° of air flow direction.
• Inch graduations on sides of 160 series to quickly determine exact insertion depth.
• Dwyer Air Velocity Calculator, direct reading flow charts and instructions included.
• Use 1/8" models in ducts as small as 4", 5/16" models in ducts 10" or larger.
• Optional mounting gland or split flange make permanent installation fast and simple.

No. A-158 Split flange Mounting
can be added to any Dwyer No. 160 Standard Pitot Tube. Cadmium 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.
No. A-159 Mounting Gland
Versatile adapter 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, install in a standard 1/2" pipe flange. 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. Telfon bushing also available. NOTE: For full insertion with this fitting, order next longer pitot tube.
No. A-397 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.

Compression Fitting - Consult Factory for pricing.: mounting option for 166/167 Series. Add -CF suffix(166-6-CF).

• Ellipsoidal tip design for improved accuracy, 1.0 coefficient
• 304 stainless steel construction adds strength, resists corrosion
• Adjustable depth indicators for fast, consistent traverses
• Alignment indicator helps keep tip parallel to flow

Series 160E Pitot Tubes are widely used in the U.K. and Europe for applications demanding high accuracy when measuring the flow of air or other compatible gases. Precision crafted tip configuration allows air to pass smoothly with minimum turbulence for consistent, reliable readings. Exterior indicator arm is aligned parallel to the 5 in. (13 cm) sensing tip so you always know that unit is properly positioned inside duct. Sliding depth indicators grip firmly to ensure uniform insertion - critical when making multiple measurements as part of a complete traverse; the best way to determine average velocity. Total and static pressure taps are 1/4" (6 mm), permanently silver soldered to the connection block, leak-proof and durable. Seven fixed length sizes are offered plus a universal model which attaches to any length of 3/4" sch. 40 pipe. See 160-U drawing.

Handy A-532 Slide Chart speeds air velocity calculations. All plastic, stays clean for years. Included with each pitot tube

Series 160S Pitot Tubes are designed specifically for flow measurement of dirty, particulate laden air or gas streams typical in smoke stack and other environmental testing. 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 for maximum accuracy, strength and long term durability. Versatile 1/8" female NPT connections easily adapt to any type of pipe or tubing. A pair of 1/8" NPT to 3/16" I.D. tubing adapters is included plus a handy molded vinyl cap to protect tip when not in use. Supplied with complete instructions.

Permanent Mounting (PM) models include 1 inch dia. welded stainless steel sleeve and adjustable compression fitting with 1 inch male NPT mounting treads. Adjust depth, lock in place.

The Model 166T Telescoping Pitot tube is a unique air flow sensor which can quickly and easily be adjusted for any duct insertion length from 11.5 to 36 inches (29.2 to 91.4 cm). Now, this single compact unit can replace up to five conventional fixed length Pitot tubes. For even greater convenience, it is securely protected by a custom fitted polyethylene carrying case. Telescoping sections lock in place as they are extended, enabling use of the handle grip to gauge proper alignment of the tip within the airstream. Stainless steel construction resists corrosion. Hemispherical tip has 1.0 flow coefficient, is 1/8" dia. (3.2 mm). Largest section is 3/8" (9.5 mm). Weight (with case) 1 lb., 9 oz. (709 gr). Case: 12.5 x 6.25 x 1.75 in.
