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 

## **ACCESSORIES** 

**Model Description A-156** Flange mounting plate 1/2˝ female NPT **A-158** 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. **A-159** 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. 

**A-160-CASE** Carrying case for pitot tubes up to 48˝ **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.
