Page 8: Application
4 Application 4 Application The S415 is the thermal mass flow meter that is designed to measure the volumetric flow and consumption of compressed air and nitrogen within the permitted operating parameters. (See Technical Data on the next page.) The default unit settings are: volumetric flow in l/min and total Consumption in m . -

5 m cable with a M8 connector on one side and open wires on the other side. To make the S415 work, one cable connection is sufficient. However, if the pulse output is to be used or the supply and the signal need to be on separate cables, a second connection cable must be ordered. - Page 16 Pin 1 Pin 2 Pin 3 Pin 4 Modbus Pulse and analog M-Bus M-Bus M-Bus M-Bus M-Bus Wire color Brown White Blue Black ATTENTION!
