摘要： The embodiments of the present disclosure provide methods and systems for energy measuring based on natural gas data of a smart gas meter, including establishing the gas IoT. The object platform obtains consumed gas volume data and location data of the smart gas meter as first data and second data, and sending them to the management platform through the sensor network platform. The management platform generates consumed gas preprocessing data based on the first data and the second data, and generates energy measurement data after performing the computation outside the gas IoT on the consumed gas preprocessing data by the cloud platform outside the gas IoT. The management platform sends the energy measurement data to the user platform configured in a regional pipeline network center through the service platform. The user platform performs gas energy measurement of the smart gas meter based on the energy measurement data.

摘要： Techniques detect a low gas-pressure condition within a region without the use of pressure sensors. In an example, gas usage at a service site is disaggregated to show use by individual appliances. A flowrate of gas at an appliance (e.g., a gas hot water tank) having a generally fixed-rate of gas-consumption is determined. Based at least in part on the flowrate of gas at the appliance, and an historical gas flowrate at that appliance, it is determined if gas pressure at the service site is lower than expected. In an example, failure of the appliance to use its typical fixed-flowrate may indicate low gas pressure at the service site. Information is obtained from a second gas meter at a second service site. Based on the gas pressure at the first and second service sites being lower than expected, a low gas pressure situation may exist in a regional area.

摘要： Embodiments of a portable verification system can move from one in-field gas flow meter location to another and temporarily connect downstream of a main pipeline's meter run or station. A control valve of the portable verification system allows volume measurement at different flow velocities to be verified. In some embodiments, the portable verification system is connected to the meter run and the main pipeline by an adjustable pipeline section. This section can extend horizontally and vertically, as well as swivel to provide versatility when connecting in the field. Adaptor fittings having one flange sized for and fitted to the inlet and outlet ends of the portable verification system and another flange sized for the meter run or main pipeline connection provide additional versatility. Downtime is limited to the time required to complete a circuit between the meter run, portable verification system, and main pipeline.

摘要： An abnormality detection method is performed in a gas supply system including a flow rate control device having a restriction part, a control valve, a flow rate control pressure sensor for measuring upstream pressure, and a control circuit. The inflow pressure sensor measures the supply pressure. An upstream on/off valve is provided upstream of the inflow pressure sensor. The method includes closing the upstream on/off valve when the gas flows at a controlled flow rate at the downstream of the restriction part by controlling an opening degree of the control valve based on the output of the flow rate control pressure sensor; measuring a drop in supply pressure on the upstream side of the control valve after closing the upstream on/off valve while keeping the control valve open; and detecting the presence or absence of abnormality in the flow rate control device based on the measured supply pressure drop.
