Flow Sensors

Flow Sensors

ESS has developed and offers a family of mass air flow sensing systems for different applications in the fields of industrial, medical as well as consumer gas flow monitoring.



Each sensing system integrates a silicon MEMS flow sensor along with its driving and read-out electronic circuitry. Significant technological advances are included in the design of the flow sensing element packaging and housing. Current solutions include low to medium flow ranges (<0.2 Nm3/m) as well as very high flows (<3.5 Nm3/m).

Custom solutions are also available on an OEM basis contact.

Low-Medium Flow Range

ESS's New Mass Flow Sensor Series (ESF) is based on the successful MFD5 flow sensor die. High accuracy, reduced size and digital output make these sensors ideal for integration in various applications requiring gas mass flow metering.
