The XR-F001 miniature gas mass flowmeter is specifically designed for the measurement and process control of various small flow gases. This series of sensors are made using advanced microelectromechanical systems (MEMS) flow sensing chips, suitable for various clean gases. The unique packaging technology makes it suitable for various pipe diameters, with low cost, easy installation, no need for temperature and pressure compensation, and can replace traditional volumetric or differential pressure flow meters.
