Before starting the wiring of the instrument, check that the supply voltage available is the
same as marked on the label of the converter.
Terminal Power supply AC Power supply DC
11 Phase DC
12 Neutral DC
In case of DC power supply, the equipment is provided by a diode bridge that allows
connecting it regardless of the polarity .
3.2.2 Pulse input wiring
Terminal
1 Voltage output +5V
2 Contact
3 Ground
This input is compatible with all oscillating piston flowmeters series COVOL, as well as
with instruments that provide an output of the following types:
- From 0 to VCC, where VCC = 5 … 24V
- NPN open collector
- Free potential contact
For those devices requiring be powered to 5VDC to generate output pulses, the MT03F
have this supply voltage in Terminal 1.
