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.
Portable ultrasonic flow meter
Handheld ultrasonic flow meter
Separate fixed ultrasonic flow meterInsertion type ultrasonic flow meter Features:
1. Insertion ultrasonic flow sensor's launch crystal contacts with the measured liquid directly which improved both the accuracy of measurement and the operation stability of the machine
2. Solved the problems where can't use clamp-on type flow sensor due to the pipe outer wall corroded seriously; And the insert type can be installed in the cement pipe, glass steel pipe where can't weld or cannot transmit ultrasonic signals.
3. Solved the clip-on sensor problem where due to a long time using and coupling agent run dry and influence the ultrasonic signal transmission.
4. Used in large diameter pipeline, more economy, and improve the measuring accuracy and reliability
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.
9:transducer:clamp-on style,insertion style,flanged pipe style.
