This ULTRATECH ULTRAC AMS 82130 Airflow Measuring Station is in new condition and guaranteed to functions 100%. It came from a local lab that was upgrading equipment and we can accept pay pal or your credit card. Please email me with any questions Air Flow Measuring Station Diameter: 30" Width: 12" li Ae 480 Sq Ft ULTRAC Airflow Measuring Stations use multiple averaging Pitots to determine total velocity and static pressure measurements. The Pitot sensors are placed across the flow stream according to industry standards for equal-area averaging (the standard Pitot traverse). ULTRAC's unique AMS construction eliminates nonessential hardware that can cause build-up of dirt and foreign matter on the measuring assembly. ULTRAC Airflow Measurement Stations are available in round, rectangular and oval configurations. All configurations feature a sensor assembly that allows for duct expansion and contraction. The 12-inch flanged steel casing has an aluminum, hexagon-celled straightening vane section that is mechanically fastened to the inlet. This eliminates turbulence and corrects flow direction, thereby increasing the velocity profile Airflow measuring stations shall be of the multiple averaging Pitot, static pressure sensor type, with all total pressure sensors distributed for equal-area averaging of flows. They shall be of unitary (spool-piece) construction, of not less than 16-gauge sheet steel with flanged duct connections. Flow-straightening vanes shall be incorporated into the structure. Internal Pitot and static sensor shall be constructed of copper to ASTM B88 standards. Instrument connections shall be 1/2" NPT Female. Mounting hardware shall not penetrate the sensor assembly. ACCURACY: +/-2% to 6000 feet per minute (+/-0.5% at 2000 feet per minute) TEMPERATURE: Maximum operating 400F PRESSURE: Maximum operating, 6-in. w.c. PRESSURE DROP: Less than 0.13 in. w.c. at 2000 feet per minute with 3/8" cell FLOW STRENGTHENING VANES: 3/8" aluminum hexagon cell MAXIMUM DESIGN FLOW: 6000 ft./min. CASING: 16-gauge galvanized sheet metal Length: 12-in. overall PITOT AND STATIC SENSORS: rigid copper, hard drawn, to ANSI H 23.1 and ASTM B88 standards INTERNAL FITTINGS: copper, to ANSI B16.22 standards PROCESS CONNECTIONS: 1/2-in.
