Portable Ultrasonic Flowmeters
The Specification of Portable Ultrasonic Flowmeter | ||
Measuring Principle |
When the ultrasonic beam is transmitting in the liquid,its transmit time is proportional to the liquid flow |
|
Application |
for continuously measuring the flow of most clear,single and pure liquid which do not have large consistence suspended matter or bubbles. |
|
Linearity |
Better than 0.5% |
|
Accuracy |
Better than 1.0% |
|
Repeatability |
Better than 0.2% |
|
Sensor Installation Method |
Clamp-on |
|
Measured Liquid |
water, sea water, sewage, alcohol, various oils such as uniform, single, stable liquid |
|
Display |
backlit LCD can display instantaneous flow, cumulative flow, velocity, time, calories and other data signal output at the same time |
|
Signal Input |
Can input two current signals(such as: temperature, pressure, liquid level, etc. signals) in order to achieve heat measurements or a dual-purpose machine |
|
Signal Output |
electric current signal 4-20mA or 0-20mA, etc. Impedance 0 - 1K, accuracy 0.1% |
|
OCT signal |
positive and negative, the net cumulative flow and the heat cumulative pulse signal or the Instantaneous flow of the frequency signal. |
|
Power Supply |
220VAC(Standard) Battery: built-in Ni-MH accumulator which can work for more than 12hours continuously |
|
Straight pipe length |
Upstream≥10D,Downstream≥5D, Length from pump exit≥30D |
|
Crust Materials |
Die-casting aluminum |
|
Other Features |
Electric 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.) |
