Fixed Ultrasonic Flow Meter

The main board is suitable for any kinds of transducers,including clamp-on type,insertion type,

• in-line type,standard in-line type and same kinds of transducers from other manufacturers.the pipe parameters and calibration parameters of water meter and in-line pipe are input by manufacturer,users do not need to input any parameter,only need to connect with flow meter to work.

Applied to on-line measure and system monitor for nearly all liquids from petrol chemical,metallurgy,electric power plant,irrigation,city water company,energy monitor fields,realize the functions of measuring and checking of flow velocity,flow rate,accumulation and heat quantity of different liquids,and flow rate on/off,liquids distinguish.

Technology Features:

1. Operating power :AC 85—264V or isolation DC 8-36VDC

2. Repeatability:better than 0.2%.accuracy:better than 1%

3. Signal output :one channel standard isolation RS485 output

1. One channel isolation 4-20mA or 0-20mA active output.

2. One channel OCT output(programmed between the pulse width(6-1000ms),default before leaving factory (200ms))

3. One channel isolation relay output,with positive,negative,net accumulation pulses and different alarm signals.

4. Signal input: two channel three wire system PT100 platinum resistor input loop,to make heat meter has the function of displaying heat quantity.

1. 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*20 backlit LCD(Chinese and English optional)

6. Operating:4*4 tactile keypad

7. Other functions:automatic memory the positive,negative,net totaliser flow rate and heat quantity of the last 512 days,128 months,10years

1. Automatic memory the time of power on/off and flow rate of the last 30 times, realize to replenish by hand or automatically,read the datas through Modbus communication protocol.

8. Protection level:mainframe:IP65, transducer:IP:68

9. Transducer: clamp-on type,insertion type,in-line type.
