Abstract

See full text

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.
