The flowmeter based virtual instrument is a new test instrument, which has more advantages than the traditional flowmeter. This flowmeter is based on Qin's model. Apply to the flowrate measurement realm the virtual instrument technique. The design method has been introduced from hardware, software and panel, modelize the different flowrate measure way, with the virtual instrument's figural calculation and show to replace the traditional flowrate measurement, realize multi-threading long-distance flowrate measure easily.
