The Series AFG Flow Grid is an outstanding simple yet accurate cost effective alternative to other duct mounted pressure sensors. Once installed and connected to a suitable measuring instrument, the device will provide years of trouble free monitoring of both air and gas flow. Installing the AFG Flow Grid is quick and easy, the AFG is supplied in kit form to allow both workshop and on-site installation into a wide range of square and circular ducts up to approximately 60".

The AFG Flow Grid is a fundamental pressure sensing device designed to transmit a continuous differential pressure signal. When this output is connected to a suitable measuring instrument (i.e., manometer, pressure transducer, etc.), it may be used to determine air velocity and volume flow rate.
