Application
3 Application
The S 418 is a thermal mass flow sensor which is designed to measure
the consumption of compressed air and other gases within the
permissible operating parameters. These parameters can be found in
the technical data section.
The S 418 can measure the following values:
• Volumetric flow
• Total consumption
• Temperature of the fluid
• Pressure of the fluid (optional)
The default factory settings are:
• Volumetric flow in l/min
• Consumption in m
3
• Temperature in °C
• Pressure in bar
Other units are configurable using the service App S4C-FS which can be
downloaded from the Google Play store or our Website.
4 Features
• Inline thermal mass flow sensor virtually independent of pressure
and temperature changes.
• Process connection of G-type thread with DN8, DN15, DN20 and
DN25 available
• Very short response time.
• Particularly suitable for measuring at-the-point-of-use flow and
consumption of compressed air and other gases.
• Integrated display showing volumetric flow and consumption.
• Options for output signals:
• Analogue 4 … 20 mA and pulse output
• Modbus interface
• M-Bus interface
• BlueTooth interface for remote sensor settings
• Configurable through Android devices
• Data logger capable of recording 5-million measurement samples
