HOW FLOTRAK WORKS

Fluid, passing through an orifice within the tube, causes a profiled float to assume a position where the forces created by flow are balanced by the weight of the float. A magnet in the float is sensed by the FloTrak system, providing a direct reading flow rate scale, optional alarms or an independent 4 to 20mA transmitter.

INSTRUMENT OPTIONS

The FloTrak meter is installed in a vertical line with flow upwards and is normally supported by the surrounding pipework. Several styles of instrument are available:

Flow Alarm Unit
The Direct Reading Indicator with one or two  fully  adjustable set-point  trips,  for connection via an interface unit.

Transmitter
4 to 20mA loop output proportional to percentage of reading. Available with the Direct Reading Indicator.
