Microthermal Measurement Principle
At the heart of every Sensirion gas meter module is a MEMS-based calorimetric micro sensor, which measures the flow of natural gas using the thermal measurement principle. The sensor element is located on a membrane and consists of a micro-heater and upstream and downstream temperature sensors. The gas flow over the membrane causes a heat transfer to the temperature sensor positioned downstream, and as a result of the temperature difference creates a precisely measurable signal. The sensor element is integrated with the signal conditioning electronics, including memory for calibration data, on a single CMOSens® chip.
