Integrated liquid flow controller incorporates valve and sensorBurkert's new Liquid Flow Controller (LFC) benefits from an integrated sensor, control electronics and proportional valves within a single compact device. This device therefore provides fast and accurate measurement and dosage of small volumes of liquids with nominal flow rates of 10–600ml/min (0.6-36l/h) with a 1:10 measuring span.

Due to its fast and accurate flow rate measurement, the Liquid Flow Controller is well suited to the dynamic control or metering of liquids such as deionised or de-mineralised water, methanol or low-viscosity oils. The LFC can be used in a large number of industrial applications including heat treatment (by carburisation or endogas generators), testing, surface coating, cooling (eg machine tools), filling, packaging and, in combination with B├╝rkert Mass Flow Controllers, the simultaneous dosage of gases and liquids in atomising or sterilisation processes.

The LFC is an intelligent, integrated, cost-saving device for applications where several liquids or a liquid and a gas must be regulated simultaneously. Previously this type of control was comparatively complex, involving the use of individual components, which raised issues of cost and interfacing incompatibility. However, the LFC overcomes these problems with an integrated design that optimises the differential pressure process for liquid flow-rate measurements to give precise, fast and repeatable measurements in a highly compact device.

Features and functions

This optimisation results in a highly efficient digital controller that combines excellent levels of reliability and functionality with comprehensive features such as: 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 RS232/RS485 or fieldbus); configurable binary inputs and outputs; and the option of IP65 protection for use in harsh environments.

The LFC is based on the successfully proven and tested software, hardware and mechanics of Burkert's mass flow controller (MFC) series. Thanks to its compact design, the controller is said to be easy to install and can be accommodated in difficult locations - such as directly behind angled piping – and, due to its narrow width per unit station, immediately downstream of angled connections. The device is available as either a closed loop controller with integral proportional control solenoid valve (LFC), or as a flow meter (LFM).
