| Digital outputs (5 wires) | Pulse output, flow direction, fraud, ground, forward pulse counter |
| Output type | NPN open collector, 30 V DC, 50 mA DC |
| Pulse duration | 125 ms |
| Pulse factor | MVM / MVM PLUS C DN 15–DN 32: 1 pulse/litre DN 40: 1 pulse/10 litres WMAP EVO |
| Cable length | 2 m |
| Wire | Signal | Description |
|---|---|---|
| White | Pulses | Pulse signal both with forward flow and reverse flow |
| Yellow | Direction | Contact closed = return flow |
| Green | Fraud | Contact open = fraud |
| Brown | Ground | Common ground signal |
| Grey | Forward pulses counter | In the event of reverse flow, the meter counts the reverse volume internally. When forward flow is restored, no pulses are generated until the reverse-flow volume returns to zero. |
