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： Nowadays many electronic devices, such as LCD projector, computer servers, and air fresher etc. require reliable air cooling system to reduce the risk of electronics damage caused by overheating. The present invention disclosed an apparatus integrated with air flow sensor as an alarm apparatus for air flow clog detection. The major prior approach for air flow circulation failure detection is based on an indirect measurement method of temperature monitoring on surrounding environments, which method is suffering from the slow response and poor identification of real-time situation. The present invention will demonstrate the advantages by directly monitoring air flow over by indirectly monitoring the surrounding temperature as for the purpose of preventing air flow path clog.
摘要翻译：如今，诸如液晶投影仪，电脑服务器和空气清新器等电子设备需要可靠的空气冷却系统，以减少过热引起的电子设备损坏的风险。本发明公开了一种与空气流量传感器集成的装置，作为气流堵塞检测的报警装置。气流循环故障检测的主要方法是基于对周围环境进行温度监测的间接测量方法，该方法受到响应缓慢和实时状况识别不良。本发明将通过间接地监测周围温度来直接监测气流的优点，以防止气流通道堵塞。
