MCS100 Miniature Mass Flow Sensor



  • Compact and lightweight
  • Low power consumption
  • High level of accuracy

MCS100 Miniature Mass Flow Sensor

The MCS100 is a compact, fast response air mass flow sensor equipped with a µF (Micro Flow) sensor chip. The MCS100 outputs mass flow signal according to the standard condition (20°C, 1 atm) of the gas flow without temperature or pressure compensation. The MCS100 offers a various flow range, in addition to its wide range ability. The MCS100 is suited for a variety of flow measurements in such as physics and industry applications.

Features of the MCS100 Miniature Mass Flow Sensor include:

  • Compact and lightweight: 33.5*10.5*17.0 mm, just 9 g (without cable)
  • Fast response time: 5 ms max.
  • High accuracy and high repeatability: Accuracy: +/-5%FS, Repeatability: +/-2.0%FS (depending on the model number)
  • Positive/negative flow measurement due to its symmetrical structure
  • Low power consumption: 12 mA max. at 24 Vdc
  • Free mounting position and not required straight piping length

Other Applications:

  • Air volume samplers
  • Gas analysers
  • Pick and place detection for minute electronic/optical devices
