Flow Meters

Flow meters are devices used to measure the volume/mass of a gas or liquid.  Flow meters are referred to by many names, such as flow gauge, flow indicator, liquid meter, flow rate sensor, etc. Most frequently flow meters are used for measuring gasses and liquids in a pipe.  Improving the precision, accuracy, and resolution of fluid measurement are the greatest benefits of the best flow meters.

    Average Flow Measuring Pitot Tube - Overview

    The Average Flow Measuring Pitot Tube is a probe that is placed into the duct to measure flow. This is often used alongside a differential pressure transmitter in flow measurement. The various pressure detecting openings on the AFMT pick up the average flow inside the duct.  AFMT then calculates the flow velocity by measuring the difference between dynamic pressure ∆P (total pressure and static pressure) and flow average velocity V. Conversion from data to flow rate happens quickly and accurately. This product is corrosion resistant, heat resistant, dust resistant, and anti-clogging.  It is widely used in harsh environments such as exhaust gas emission, vacuuming, and dust wind speed calculation.  Also used in ventilation and air-conditioning systems.
