PICKOFF COIL SENSORS

The FC7 converts the pulsed output from your flowmeter into an analogue 4-20mA signal.

RN Turbine Flowmeter
Quick and easy to install
Preset to your requirements
Monitor consumption and flow rates Improve your process Reduce costs and waste 10 point linearisation Works with all pulsed flowmeters ISO 9001 certified manufacturer Weatherproof enclosure
Outputs for PLC’s,computers etc.
Highly accurate
Monitor consumption and flow rates
High reliability
Immunity to electrical noise
Weatherproof enclosure

Application
The FC7 will convert a pulsed flowmeter signal into a loop powered 4-20 mA signal for instruments such as PLC’s, computers, flow controllers, chart recorders or local displays.

Installation
The robust aluminium enclosure allows the instrument to be installed almost anywhere. It can be mounted in a panel, on to a wall or on to the flowmeter.

Instrument Function
The FC7 will accept pulsed signals from any flowmeter. It provides you with an analogue output of 4 - 20 mA. It improves the accuracy by correcting for the non linear performance of flowmeters.

Setup
The instrument is preset for your flowmeter using up to 10 linearisation points from the calibration certificate.
