EL-FLOW Select F-132M

Gas Mass Flow Meters for medium flow rates

Bronkhorst® model F-132M Mass Flow Meters (MFMs) are suited for precise measurement of flow ranges between 0,3…15 ln/min and 5…250 ln/min at operating pressures up to 400 bar. The MFM consists of a thermal mass flow sensor and a microprocessor based pc-board with signal and fieldbus conversion and a PID controller for optional mass flow control by means of a separately mounted control valve.

EL-FLOW® Select 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 CANopen®, DeviceNet™, EtherCAT®, PROFIBUS DP, PROFINET, Modbus or FLOW-BUS protocols.
