LIQUI-FLOWTM series L10I / L20I industrial style Liquid Mass Flow Meters / Controllers The LIQUI-FLOWTM series L10I/L20I digital Liquid Flow Meters / Controllers for low flow ranges are equipped with a rugged 'industrial style' (IP65) pc-board housing for use in industrial environments. The instruments operate on a thermal, thru-flow measuring principle. The flow meter can be connected to a control valve to form a closed control loop. The standard direct acting valve (model C2I) is normally closed, has a pressure capability of 100 bar (1500 psi) and a purge connection for easy elimination of air or gas. Lowest range 0,25 ... 5 g/h. Highest range 20 ... 1000 g/h. Note: ranges for fluids with thermal properties similar to H2O. "Multibus" digital communication Bronkhorst High-Tech developed their digital instruments according to the flexible "multibus" concept, due to which the instruments can be equipped with on-board interface board with DeviceNetTM, Profibus-DP®, Modbus or FLOW-BUS protocol.
