The flow rate of 720ca-ml (red) 0-301002005001000ml720ca-l (yellow) 0-2 / 3 / 45l720ca-m (blue) 0 ~ 1020304050l720ca-h (green) 0-100150l was measured by using the principle of "precise shunt technology + mass flowmeter (air)"
It adopts EPA standard cutter connection size, plug and play, precise shunt technology, stable flow rate and small additional resistance. With adapter, it can change the placement direction. Touch interface is simple and practical, easy to operate. It can display instantaneous flow on the same screen, set the average flow rate in time period, and cumulative flow. It can select standard flow (0 ℃, 20 ℃, 25 ℃) or working condition flow according to needs. It contains wireless module, Remote setting and recording of flowmeter parameters, automatic temperature and pressure compensation ● automatic brightness adjustment, built-in lithium battery, can work continuously for 18 hours, AC power supply through adapter
