Digital Flow Meter

The DF-R280 Series has various applications from in-line tests to lab use. It mainly features a large LCD screen that displays more information besides flow data. The DF-R280 excels at high-accuracy flowmeters for labs, flow and leak tests for auto parts, and flow tests for gas equipment, valves, medical devices, pumps and pipes. The support reading accuracy is around ±1%. It is a great choice for a digital flow meter.
