1: operating power :AC 85—264V or isolation DC 24V
2: current: 50mA(under the condition of connection without keyboard display and sound of buzzer)
3:output optional: 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 leaving factory (200ms))
4:input optional: two channel three wire system PT100 platinum resistor input loop,to make heat meter has the function of displaying heat quantity.
5:display:2*10 backlit LCD(Chinese and English optional)
6: operating:magnetic 4 keypads to operate
7:other functions: automatic memory the positive,negative,net totaliser or flow rate and heat quantity 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.
1:PT100 three wire platinum resistor( a pair,used for heat meter)
2:ultrasonic thickness gauge: (measure the thickness of pipe,reduce error,increase accuracy)
