Bronkhorst® model L13V12 Liquid Flow Controllers (LFCs) are suited for precise measurement and control of flow ranges between 0,25…5 g/h and 5...100 g/h at operating pressures up to 100 bar. The LFC consists of a thermal mass flow sensor and a microprocessor based pc-board with signal and fieldbus conversion and a PID controller for mass flow control by means of an integrated control valve.
LIQUI-FLOW™ series are equipped with a digital pc-board, offering high accuracy, excellent temperature stability and fast response. The main digital pc-board contains all of the general functions needed for measurement and control. In addition to the standard RS232 output the instruments also offer analog I/O. As an option, an on-board interface can be mounted to provide DeviceNet™, PROFIBUS DP, Modbus, EtherCAT® or FLOW-BUS protocols.
