Ultrasonic flow meter is designed to measure the velocity of liquid within a closed conduit. It uses the well-known transit-time measurement principle, plus our proprietary signal processing and ultrasonic transceiving technologies.
1. ultrasonic flow meter
2. DN15-DN6000
3. wide use at multiple materials of pipe
5. 10 yrs working experience foreign trade
Ultrasonic Flow Meter TUF-2000W
The new generation of ultrasonic flow meter TUF-2000W is developed, with the experience of 12 years of manufacturing ultrasonic flow meter, based on our version-12 and version-15 flow meters. By using the high performance MSP430FG4618 microprocessor made by Taxes Instruments, it is intend to provide our customers with lower cost but of high performance general purpose ultrasonic flow meter.
1:operating power:isolation 8-36VDC
2:current: 50mA(under the condition of connection without keyboard display and alarm of buzzer)
3: signal output: one channel standard isolation RS485 output
One channel isolation 4-20mA or 0-20mA passive output.
Two channel OCT output(programmed between the pulse width(6-1000ms),default before out of factory (200ms))
4: signal input: two channel three wire system PT100 platinum resistor input loop,to make calorimeter has the function of displaying heat quantity.
Three channel 4-20mA input optional,accuracy:0.1%,has the ability to input the signals of pressure, liquid level, temperature and so on.
5:display:2*10backlit LCD,displaying instant flow rate,velocity,positive,negative,net totaliser flow rate.
6:operating: 4 keypad tactile keyboard operating
7:other functions: automatic memory the positive,negative,net totaliser or flow rate and thermal energy of the last 512 days,128 months,10years
Automatic memory the time of power turning on and off and flow rate of the last 30 times, realize to compensate by hand or automatically,read the datas through Modbus communication protocol.
8:protection level:IP57
9:transducer:clamp-on style,insertion style,flanged pipe style.
