µ-FLOW series L01 Mass Flow Meters / Controllers for liquids µ-FLOW are Liquid Flow Meters/Controllers for ultra low flow ranges. 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. Lowest range 1,5 ... 30 mg/h for meters and 5 ... 100 mg/h for controllers. Highest range 0,1 ... 2 g/h. Note: fluids with thermal properties similar to IPA / H2O. Flow control Flow control is achieved by integrating a control valve onto the body of the Liquid Flow Meter. This control valve has a purge connection to eliminate air or gas during start-up. The electronic control function forms part of the normal circuitry in the meter. Features: No moving parts Thru-Flow measurement Attitude insensitive Fast and accurate measurement Negligible dead-volume (sensor: 1,5...33 µl) In combination with a control valve: continuous and stable control Analog or digital: RS232, Profibus-DP®, DeviceNetTM, Modbus or FLOW-BUS Stainless Steel sensor NEW: 1000 bar (15000 psi) LFM for 150 up to 450 mg/h FS (based on H2O) Applications: Pharmaceutical industry Food industry (flavors, additives) Biotechnical industry Analytical laboratories Evaporation processes (see CEM-system) HPLC applications
