The sensor element is based on commercially available MEMs components and is assembled using automated methods used every day in the electronics industry. This makes it 1,000s of times smaller than competing instruments and 100s of times cheaper.
The patented inference sensing method can be adapted to determine multiple gas properties:
The sensor primarily measures the the dynamic viscosity. Typically combustible gases with increasing calorific values have a lower viscosity and inert gases have a high viscosity. Using this principle the combustion properties can be inferred by measuring the viscosity of the gas mix. By integrating other physical measurement properties, such as thermal conductivity, an accuracy of less than 0.3% can be achieved.
The dynamic viscosity is measured by pumping the sample gas through a capillary and measuring the pressure change across it. Uniquely the sensor uses a miniaturised heater to pump, which means the pressure can be generated with no moving parts.
The gas sample is taken from the gas flowing through the sensor by first "exhaling" the previous gas sample by heating it so it flows out then when the heater is switched off a new gas sample it drawn in. The faster the new sample can be "inhaled" the lower viscosity.
The sensor is calibrated to measure Wobbe Index. It is possible to reconfigure it to measure the Higher Heating Value, Lower Heating Value, or Dynamic Viscosity.
