Stainless Steel Pitot Tubes
ASME Design Meets AMCA & ASHRAE Codes



Stainless Steel  Pitot Tube


Standard Model 160 Pitot Tube

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" diameter or as    large as 36' diameter.
- A universal model fits user supplied ? schedule 40 (standard) pipe in any length.
- Several convenient mounting options are available for permanent installations.

    
[특 징]
 -  No calibration needed.

 -  Precisely located, butt-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, 1/8" models to 800°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.


 Pitot Accessories
ACCESSORIES

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 slices over tube and provides permanent, secure mounting. Where duct interior is accessible, use the washers and jam nut supplied. For lind 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.

              1-3. 피토 튜브(Pitot Static Pressure Probes)- United Sensor product

FOR MEASURING TOTAL
AND STATIC PRESSURES
OF A MOVING FLUID

-United Sensor stainless steel Pitot Static probes sense total and static pressures at the same point   in a moving fluid.
-These measurements are often sufficient for calculating flow velocity and weight flow rate if the  density is known. 
-As a fluid's density is often a function of its temperature, it may be necessary to measure
 temperature in addition to velocity pressure. 
-Pitot - Static probes may standardly be equipped with a thermocouple for simultaneous
 temperature measurements at the same point in the fluid stream as pressure measurements.
-The shape of the probe measuring tip determines the sensitivity of the Pitot - Static probe to flow  angularity (yaw and pitch angle error) caused by flow not parallel to the head. 
-The length of the head governs sensitivity to Mach Number errors; the longer the head, the more  accurate the reading over a wide flow range. 
-The two most popular designs for aerodynamic measurements are the modified Prandtl type with  a head 14 probe diameters long and the NPL with a head 24 diameters long. 
-There is very little difference in calibration of the two designs, and because the Prandtl type is  more compact, it is more generally used. 
-United Sensor Pitot - Static probes are of the modified Prandtl type.

How to Order :

To order standard Pitot - Static probes, select the probe Type (e.g. Type PA, PB, etc.) best matching your application requirements.  Then order from the specification chart the ordering Part Number (e.g. PAA-8-KL), which covers the exact specifications shown.
To order non-standard probes (e.g. special lengths, configurations, constructions) consult United Sensor.
