The S418 Compact Flow Sensor provides compressed air flow and gas monitoring directly where it is needed. The seamless integration into a compressed air and gas system makes it an affordable and easy to install flow measurement solution.

Get Your Compressed Air and Gas Cost Under Control

The S418 helps you to improve your compressed air system efficiency and get your operating costs under control. By monitoring flow, consumption, pressure and temperature in one device optimization potential can be easily detected.

The integrated data logger helps to collect and save your data, which can be imported into data analysis software via Modbus outputs.

Wireless Communication and Configuration

The S418 Flow Sensor comes standard with wireless communication interface to quickly and easily check the flow sensor readings. This can also be used to adjust the settings via the SUTO flow sensor app S4C-FS. Flow sensor configurations and online real-time data readings have never been easier.

Integrated Flow Conditioner

To ensure accurate readings regardless of the design of the piping system, the S418 has a built-in flow conditioner. Due to the flow conditioner design, no straight pipe inlet sections are needed to provide reliable compressed air and gas flow monitoring.

Thermal Mass Flow Technology

With the use of thermal mass flow technology, the S418 is virtually independent of pressure and temperature changes. This makes it resistant to environmental influences and at the same time highly precise and reliable.

The S418 Flow Sensor is providing a state-of-the-art and easy to install solution for monitoring your gas and compressed air flow system and usage. Should you have any special requests, such as custom flow ranges or different gas types, please contact us here.
