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, gauge 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.
