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℃, |
||
Fluid Temperature | Normal sensor:-30 ~ +80℃ High temperature sensor:-30 ~ +160℃(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 |

●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. |
