Basic overview
_{VT2/3WE serial Vortex flowmeter integrated with 16-bit MCU processor, and the amplifying circuit is of analog type. The flow rates of gas, liquid and steam can be accurately measured within a conventional flow range. Can be set by the dial switch to adapt to various caliber and all kinds of measuring media. VT3WEC system communicate according ModBus485-RTU protocol specification, and can use battery power. VT2WE system output 4-20mA current and isolated original Pulse.}

Wire connection
the terminal blocks is on the amplifier board. The large terminal is the required main terminal and the small terminal is the auxiliary terminal for additional function wiring.
 

Wire connection of VT3WE

Main power supply and output signal terminal

GND

Fout

V +

"GND": is the "-" end of the power supply.    
"Fout": is the pulse output terminal.     
"V+" : is the "+" terminal of external 12V~24VDC power supply.
Note:
When V+ and GND are connected to an external power source, the circuit works (the battery-powered model is transferred to an electrician), and the pulse output is drawn from Fout.
Auxiliary wiring (small terminal) the double-pin jumper wire between the main terminal and the auxiliary terminal is the battery switch. When  it is short connected battery is on; battery is off, When it is disconnected.

Battery and communication terminal

+ 3 V6

3 V6 -

CMB-

CMA+

1) battery terminal(1,2 bit right of small terminal)
"+3V6": connect to the "+" end of 3.6V lithium battery.     
"3V6-" : connect to the "-" end of 3.6V lithium battery
2) communication terminal (3,4 bit left of small terminals)
"CMB-": connect the "-" or "B" end of RS485 wires.
"CMA+": connect the "+" or "A" end of RS485 wires.


Wire connection of VT2WE
1. Main power supply and current output terminal

-

+

"-" : is the output terminal of 4~20mA current. and also is the "-" end of 15-24v power supply    
"+" : is the "+" end of 15-24v power supply
The ammeter or sampling resistance is between the "-" end and the negative of power.
Auxiliary terminal (3 small terminals)

V +

Fout

GND

"V+" : connect to the positive of the power supply (+12V).
"Fout": is the pulse output signal terminal.
"GND": connect to the negative of the power supply.
This pulse output must be used in the case of power supply in the main current loop. The output is the uncorrected original pulse with 50Hz excised with light isolation, which is usually used in calibration. The output signal is NPN open collector output with 2K pull-up resistance.
