Page 23: Sensor Signal Outputs
The flow meter will send out one pulse per consumption unit. This pulse output can be connected to an external pulse counter to count the total consumption. The number of m per second are summed up and indicated after one second. Pulse length depends on flow rate. S402... - Page 24 10 Signal outputs In case that the flow rate is too high and the S402 cannot output pulses with the default settings (one pulse per one consumption unit), use our mobile service app S4C-FS to set the pulse output to 1 pulse per 10 consumption units or 1 pulse per 100 consumption units.
