 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.
APPLICATIONS
The AFG Flow Grids will give useful and reliable readings in a wide variety of 'in duct' locations often where other flow rate measuring devices are found to be unsatisfactory. The signal from an AFG Flow Grid can be used in a variety of ways, for example:
- To display differential pressure, velocity of volume flow using a micro manometer, gage or transmitter.
- To give a warning of over or under flow rate using a pressure switch.
- To control air supply in a system by connection the grid to a pressure transmitter with an electrical output which can be used to feed into a control system.
- To display differential pressure on a simple fluid manometer to give visual indication of changes in volume flow rate in the duct.
