摘要： An all-electronic utility gas meter using with micromachined (a.k.a. MEMS Micro Electro Mechanical Systems) silicon sensor to measure gas metrology data for custody transfer or tariff in city gas metering application is disclosed in the present invention. The meter has two separate metrology units. One of the units is located in the main flow channel with the insertion probing configuration while the other is configured as a bypass unit assembly with the main metrology unit. The bypass metrology unit can perform independent metrology tasks and can be exchanged onsite during service, maintenance or repair without dismantle the meter from the service pipeline. The bypass metrology unit also can be used to compare the measured data from time to time and performance self-diagnosis that shall help the performance and data authentication during the meter field service. Both of the units can be powered by battery or external sources. The units can be connected to network as well as provide internal plural storages for data transmission and safety.
摘要翻译： 在本发明中公开了一种使用微机械（即微机电MEMS机电系统）硅传感器来测量用于城市燃气计量应用中的监管转移或关税的气体计量数据的全电气公用事业气体计量器。 仪表有两个独立的计量单位。 其中一个单元位于具有插入探测配置的主流道中，而另一个被配置为与主计量单元的旁路单元组件。 旁路计量单元可以执行独立的计量任务，并可在维修，维护或维修期间进行现场交换，而无需将仪表从服务管道拆除。 旁路计量单元还可用于比较不时测量的数据和性能自我诊断，这将有助于仪表现场服务期间的性能和数据认证。 这两个单元可以由电池或外部来源供电。 这些单元可以连接到网络，并提供用于数据传输和安全的内部多个存储。

摘要： This invention is related to an apparatus which incorporates a microfabricated silicon mass flow sensor to measure city gas flow rate in a medium pressure range for utility industry which is dominated by conventional mechanical meters such as turbine and rotary meters. The microfabricated mass flow sensor is so called micro-electro-mechanical systems (a.k.a. MEMS) device. Due to the small feature size of micro scale for MEMS mass flow sensor, the invented apparatus includes many advantages such as low power consumption, compact package, high reliability and extended dynamic measurement range. This apparatus is also provided with a stable flow conditioning to achieve a desired dynamic range capability. Furthermore, because of the high accuracy characteristic, the apparatus in this invention could be applied for custody transfer or tariff in utility industry as well.
