Burkert’s new Liquid Flow Controller (LFC), integrates a sensor, control electronics and proportional valves. The LFC accurately measures and doses small volumes of liquids with nominal flow rates of 10-600ml/min with a 1:10 measuring span.

The LFC is suitable for the dynamic control or metering of liquids such as deionised or demineralised water, methanol or low-viscosity oils. The LFC can, therefore, be used in a number of industrial applications, including heat treatment (by carburisation or endogas generators), testing, surface coating, cooling (machine tools), filling, packaging and, in combination with Burkert mass-flow controllers (MFCs), the simultaneous dosage of gases and liquids in atomising or sterilisation processes.

The digital controller features flow-rate measurement inside the medium flow (without moving parts); configuration and diagnosis via a serial interface using free Burkert software; an integrated totaliser for consumption analysis; flexible interfaces (analogue/digital via fieldbus or RS232/RS485); configurable binary inputs and outputs; and the option of an IP65 version for arduous environments.

The LFC is based on the tested software, hardware and mechanics of Burkert's MFC series. The device is available as either a closed-loop controller with an integral proportional control solenoid valve (LFC) or as a flowmeter (LFM).
