Model TFS2200 Thermal Gas Flow Modules for Residential Smart Gas Metering Description The model TFS2200 thermal gas flow modules are specially developed for residential smart gas meter applications. 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 made by MEMS process, which is the core of the TFS2200. Thanks to MEMS facility, 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 TFS2200, 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 TFS2200 modules can be customized for the best integration into customer gas meters. Features integrated temperature and gas-recognition sensors low power consumption high accuracy: up to ±1.5%rdg wide range: 0~6m3/h BCM SENSOR TECHNOLOGIES BVBA Industriepark Zone 4, Brechtsebaan 2 website: www.bcmsensor.com B-2900 Schoten - Antwerpen, BELGIUM email: [email protected]
