Page 5: Usage And Safety
The specially designed circuitry provides amplification as well as small signal processing capability. Siargo's flow sensors utilize the thermal mass flow technology using energy balance design. Unlike the other MEMS flow sensing technologies, Siargo's flow sensors have multiple sensors integrated on a single silicon chip. -
Page 6: Working Principle
3. Working Principle 3.1 Working Principle Siargo's proprietary MEMS flow meters utilize the insertion sensing approach that can measure gas flows in a large pipe. The MEMS flow sensor integrates a micro heater, local temperature sensors and environmental temperature sensors onto a single package. At the no flow, a stable temperature field (distribution) around the micro heater is maintained. -
