Features S 401:

• Tube diameters of DN25 to DN500.
• 2 installation types: center installation and 100 mm insertion depth installation for bigger pipes (> DN250)
• Installation under pressure through 1/2” ball valve
 
-----------------------------------------------------------------------------------------
• Measures standard flow, mass flow, consumption and temperature
• Thermal mass flow, independent of pressure and temperature changes
• IP65 casing provides robust protection in rough industrial environment
• Very fast response time
• High accuracy and wide measuring range
• Isolated mA and pulse output signals or Modbus/RTU interface
• Selectable gas type (some gases require real gas calibration!)
• App for mobile phones and tablets for sensor settings via BlueTooth
• Sensor can be calibrated in 2 different gases

Stated flow values are at standard conditions of Ps=0.1MPa and Ts=20°C with medium air.
 
The table above shows flow ranges up to 300 mm pipe diameter at standard conditions in air. At other standard conditions and in other gases flow ranges are different and data are available on request
 
In larger pipe diameters flow can also be measured.
