Always observe operating temperature and humidity as stated in the the technical data. • It is strongly recommend not to install S418 permanently in wet air/gas conditions, which exists usually right after a compressor outlet. -
Page 17: Electrical Connection
5 m cable with a M8 connector on one side and open wires on the other side. To operate the S418, one cable connection is sufficient. However if the pulse output is to be used or the supply and signal should be on separate cables, a second connection cable must be ordered. -
Page 18: Signal Outputs
The device outputs one pulse per a 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. S418... -

Page 20: Connect Several S418 To Modbus Master
FLOAT 4-byte 9.3.2 Connect Several S418 to Modbus Master The S418 with Modbus/RTU interface can be easily daisy-chained to a Modbus Master device. This master can be either SUTO displays and gateways or any third-party Modbus/RTU master. Through this method you can add up to 16 flow meters to the master device. - Page 21 (A553 0123). • The shield must be connected at one end to the master GND connection. • At the end of the bus, a 120 Ohm resistor should be placed a termination resistor. See the below picture for details. S418...
- Page 22 9 Signal Outputs 9.3.2.3 Create Daisy-Chain using RS-485 Splitter To connect the S418 to the daisy-chain, the RS-485 splitter (A554 3310) and the M8 to M12 converter cable (A553 0161) are needed. Furthermore place a M12 termination resistor (C219 0055) at the last splitter in the daisy-chain, as show in the figure below.
