| Portable Type | Handset 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 | Steel,stainless steel,cast iron,PVC,cement pipe and other pipes whose materials are close . Liner are Optional(there can not be the interspace between the liner and the pipe exine) | ||
| Pipe Size | S model sensor(with magnetism 50-100mm) M model sensor(with magnetism 50-700mm) L model sensor(no magnetism 300-6000mm) | ||
| Sensor Installation Method | Clamp-on | ||
| Measured Liquid | water,sea water,acid and alkali,food oil, gas,coal oil,diesel oil,petroleum,alcohol,beer etc.these single and pure liquid which can transmit ultrasonic beam | ||
| Ambient Temperature | Convertor -10-70°C, | ||
| Fluid Temperature | Normal sensor -30 ~ +80°C High temperature sensor -30 ~ +160°C(only 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 | EXd BT4 |
| 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 days,former 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. | |||
