water flowmeter The Specification of Portable Ultrasonic Flow meterMeasuring PrincipleWhen the ultrasonic beam is transmitting in the liquid,its transmit time is proportional to the liquid flow Applicationfor continuously measuring the flow of most clear,single and pure liquid which do not have large consistence suspended matter or bubbles. LinearityBetter than 0.5%AccuracyBetter than 1.0%RepeatabilityBetter than 0.2%Sensor Installation Method Clamp-on Measured Liquidwater, sea water, sewage, alcohol, various oils such as uniform, single, stable liquidDisplaybacklit LCD can display instantaneous flow, cumulative flow, velocity, time, calories and other data signal output at the same timeSignal InputCan input two current signals(such as: temperature, pressure, liquid level, etc. signals) in order to achieve heat measurements or a dual-purpose machineSignal Outputelectric current signal4-20mA or 0-20mA, etc. Impedance 0 - 1K, accuracy 0.1% OCT signalpositive and negative, the net cumulative flow and the heat cumulative pulse signal or the Instantaneous flow of the frequency signal. Power Supply220VAC(Standard) Battery: built-in Ni-MH accumulator which can work for more than 12 hours continuouslyStraight pipe lengthUpstream≥10D,Downstream≥5D, Length from pump exit≥30DCrust MaterialsDie-casting aluminumOther FeaturesElectric relay: Can output nearly 20 kinds of source signals (such as no signal, the reverse flow, etc.)Sound Alarm: Can set the alarm buzzer sounds (such as the flow is max, or too small, etc.)
