Influx FloTrak metal VA flowmeter

The Influx FloTrak metal VA flowmeter is designed for the measurement of gas and liquid. 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 a 4-20 mA output.

The flowmeter is installed in a vertical line with flow upwards and is normally supported by the surrounding pipework. Several styles of instrument are available. As a direct reading indicator it provides clear indication over a 100 mm long scale, and can be scaled to suit exact process conditions. As a flow alarm unit, the direct reading indicator also provides one or two fully adjustable setpoint trips, for connection via an interface unit. As a flow transmitter, it provides a 4-20 mA loop output proportional to percentage of reading.

The flowmeter has simple construction and is rugged and easily installed. It is claimed to have a stable zero point unaffected by installation and low hysteresis. Gas damping is fitted as a standard on gas ranges, and alternative flange connection ratings and types are available on request, as well as special calibrations or flow ranges. Approvals include EEx ia IIC T6 and EEx nA T6.
