Page 23: Sensor Signal Outputs
The sensor 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 consumption rate. S 430... - Page 24 In case the flow rate is higher than 50 m /s, l/s of ft /s, the S 430 can not output the pulses with default settings (one pulse per consumption unit). For this the pulse can be set by our service software or a connected display to 1 pulse per 10 consumption units or 1 pulse per 100 consumption units.
