Calibration, lifetime and FAQ
Thanks to the stability of the MEMS-based sensor element and the robust mechanical design, Sensirion Mass Flow
Controllers do not drift and do not require recalibration in the field.
High manufacturing standards used during production ensure that our Mass Flow Controllers are extremely reliable and
have a very low failure rate. This is supported by field surveys and measurements.
Mean time between failures of Sensirion devices has been found to be 169 years. The detailed analysis based on several
thousand parts in the field can be found in a dedicated application note:

The high-quality valves used are rated for 100 million cycles. The EEPROM memory of the MFC is rated for 50 000 write
cycles. This de-facto limits the number of times a calibration, user gain etc can be changed. Please take this into
consideration, when implementing the Mass Flow Controller.
