Model TFS2000 Thermal Gas Flow Modules for Inline Gas Measurement Description The model TFS2000 thermal gas flow modules are specially developed for inline gas measurement which requires the module directly connected to the pipeline. Aimed at the smart gas meter application, both a temperature sensor and a gas-recognition sensor are integrated in this module. The temperature sensor signal can be used for temperature compensation on flow data, while the gas-recognition sensor can be used to identify whether the flow medium is air or natural gas. The module contains a thermal mass flow sensor which is made by MEMS process. Thanks to MEMS process, this model has advantages of low power consumption and wide measuring range with high accuracy, and are benefit a compact design. As there is no moving part in the TFS2000, the module forms a solid state sensor system with excellent stability and reliability. To prevent any possible influence due to metal particles contained in gas flow, the flow channel is specially designed and a protective layer is applied to the surface of the flow sensor. In case of high-volume orders, the housing of TFS2000 modules can be customized for the best integration into customer gas meters.
