Mass Flow Meter SFM3200-AW
Autoclavable Flow Sensor for Expiratory Measurements
The SFM3200-AW mass flow meter is able to withstand autoclave procedures, making it autoclavable, cleanable and therefore reusable.
Due to the special design of its flow channel, the pressure drop through the sensor element is very low. Thus, the sensor is the perfect choice for expiratory flow measurements in medical applications. It measures flow rates highly accurate and performs superiorly not only at low flows, but also at rates up to 250 slm. Furthermore, the SFM3200-AW features a very fast signal processing time and superior robustness.
The SFM3200-AW sensor is, as are all Sensirion sensors, based on the patented CMOSens® Technology. The technology combines the sensor element and the analysis electronics on a single microchip. Thus, the CMOSens® gas flow sensor measures long-term stable and noise free and a very fast and highly precise sensor signal results.

Autoclavable Sensors for Medical Applications
Sensirion has been developing and marketing flow metering sensors for many years. Until now, these sensors have been used in ventilation and anesthetic devices to measure the volume of clean air administered to the patient. But apart from this clean tract, both ventilation and anesthetic procedures need a means of metering the flow of exhaled air. This is known as either proximal or expiratory flow metering. In both cases, the sensor comes into contact with air from the patient that is potentially infected with germs and pathogens. These sections of the apparatus are therefore comprised of disposable parts or hygienically sterilizable. Now Sensirion has developed new flow metering devices that are autoclavable and can be washed.
