SUTO S450 Thermal Mass Flow Meter (ATEX/EX)

The SUTO S450 flow sensor is based on the thermal mass flow principle. It measures volumetric standard flow over a wide measuring range. The result is pressure and temperature independent. So it’s perfectly designed to measure your compressed air flow and consumption.

The S450 is designed specifically for harsh environments. The enclosure with IP67 allows all-weather applications; all parts that come into contact with the measurement medium are stainless steel 316L. This allows applications in the pharmaceutical and food industry and the measurement of corrosive and contaminated gas. Installations in an explosive environment can be done through the optional ATEX approval. Various gases can be measured, such as air, oxygen, argon, carbon dioxide, natural gas, hydrogen, methane, etc. Basically, any gas mixture can be measured as long the mixing ratio and its components are known and constant.

  • Heavy-duty version compressed air flow meter
  • Direct measurement of mass flow and standard flow without the need of pressure compensation
  • A wide range of tube sizes are supported (insertion type for big pipe diameters / inline types for small ones)
  • No moving parts, non-clogging
  • All parts which come into contact with the measurement medium are made of stainless steel 316L
  • Robust metal enclosure suitable for outdoor applications in harsh environment
  • Wireless communication interface for sensor settings on site
  • The display shows flow rates, consumption, medium-temperature and diagnostic results
  • 2 analog outputs (4 … 20 mA) and 1 pulse output
  • Available options:
         – Fieldbus interface: HART, Modbus, M-BUS
         – Hazardous approval ATEX: II 2 G Ex d IIC T4, IECEx approval, GB Ex approval
         – 2-directional measurement
