Product description MFS - Micro Flow Sensor

The IST AG MicroFlowSens (MFS) technology was developed for fast flow measurements. Due to the membrane system, the thermal mass is reduced to the minimum resulting in a very fast response time and low power consumption. In addition to measuring flow rates, the MicroFlowSens offers an outstanding sensitivity and is able to detect flow direction. The MFS flow sensor is optimal for limited space system integration and is available as integrated sensor on a PCB.

The MFS thermal flow sensor can be used in a wide flow range from 0 to 150 m/s (CTA mode) and in a temperature range from -40 °C to +80 °C. It is used for flow measurement of a wide variety of gases. A special feature of the MFS sensor is that it is also suitable for industrial flow applications with smoke or exhaust gas development. The MFS sensor can be operated in either anemometric or calorimetric mode. It is also suitable for measuring the flow direction. MFS flow sensors are based on a photosensitive glass substrate with a thin polymer layer that serves as a membrane.

The IST AG MFS gas flow sensor is optimal for measurements in process control, hand held devices and in medical applications.
