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:","Applications:
