Venturi Tubes

McGill offers venturi tubes linked with airflow meters for four different leakage measurement ranges. Using a venturi tube and a digital flow meter with a variable speed blower, McGill's Leak Detective Test Station can be quickly set up to measure leakage rates in duct systems with desired static pressures as high as 10 inches wg. The venturi tubes are calibrated and traceable to the National Institute of Standards and Technology (NIST). The calibration results in factors that are programmed into the digital flow meters to give direct readings of standard cubic feet per minute (SCFM) with an accuracy of 2 percent over the recommended flow range. A Certificate of Calibration is provided with each venturi tube/flow meter, which has been approved, stamped, and signed by a Professional Engineer.
