产品介绍
LIQUI-FLOWTM Series L10\/L20 are digital Liquid Flow Meters\/Controllers for 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 0,25 ... 5 g\/h.Highest range 20 ... 1000 g\/h for fluids with thermal properties similar to H2O.","Note: For ultra low flow ranges, Bronkhorst High-Tech offers the µ-FLOW series. Ranges: 1,5 ... 30 mg\/h up to 0,1 ... 2 g\/h IPA- or H2O-equivalent.","Features:","Applications:","Features:","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. Alternatively the liquid flow can be controlled using a close-coupled pump.
