Portable

 

Tcchnical Parameters:

Types		Portable Type	Handheld Type	Fixed Type
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%
Velocity Range		0±32m/s
Pipe Materials		Steelstainless steelcast ironPVCcement pipe and other pipes  whose materials are close . Liner are Optionalthere can not be the interspace between the liner and the pipe exine)
Pipe Size		S model sensor(with magnetism:15-100mm         M model sensor(with magnetism:50-700mm                L model sensor(no magnetism:300-6000mm
Sensor Installation Method		Clamp-on
Measured Liquid		watersea wateracid and alkalifood oil gascoal oildiesel oilpetroleumalcoholbeer etc.these single and pure liquid which can transmit  ultrasonic beam
Temperature	Ambient Temperature	Convertor-10-70,
	Fluid Temperature	Normal sensor-30 ~ +80                     High temperature sensor-30 ~ +160only for Smodel and Mmodel,no magnetism
Display		2 lines display the instantaneous flow,totalize flow and signal state		2×10LCD display.Display the instantaneous flow and the positive negative net totalizer flow and velocity etc.
Signal Input		No signal input	No signal input	4-20mA analog signal input,accuracy 0.1%,can imput pressure,liquid level,temperature and so on.PT100 platinum resistor.
Signal Output		RS485		4-20mA or 0-20mA current signal outputOCT output (pulse width 6~1000ms,factory setting is 200ms)relay can put out positive,negative,net accumulative pulse and the alarm signal.RS485 output IP: IP65, IP68
Communication Protocol		MODBUS  Protocol
Power Supply		220VAC(Standard) Battery: built-in Ni-MH accumulator which can work for more than 12hours continuously.		220VAC(Standard), 24VDC(optional)
Straight pipe length		Upstream≥10D,Downstream≥5D, Length from pump exit≥30D
Ingress Protection Ratings		Convertor: IP65,     Sensor: IP65	Convertor: IP65,     Sensor: IP65	Convertor: IP65,             Sensor: IP68
Explosion Proof Rating		No explosion proof	No explosion proof	EXdBT4
Crust Materials		Die-casting aluminum	PVC	Die-casting aluminum
Other fuctions		built-in whole thermal printer,which can relize in-time and    set-time print	----------------------------	Auto-memory the positive,negative,net accumulative flow and heat of former 512 daysformer monthes,former 10 year;Auto-memory the power-on and power-off time and the flow of former 30times,and also can realize auto and manual adding;   can read out the datas by MODBUS protocol,self-diagnose to tell the current working state.
		self-diagnose:tell the current working state whether it is normal or not.
