Page 8: Application
4 Application 4 Application The S415 is the thermal mass flow sensor 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 . -

Page 12: Installation
• The sensor is for indoor use only! At an outdoor installation, the sensor must be protected from solar radiation and rain. • It is strongly recommend not to install S415 permanently in wet environment which exists usually right after a compressor outlet. -
Page 13: Electrical Connection
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 14: Sensor Signal Outputs
The sensor 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.
