摘要： Embodiments relate to a system including a gas meter, regulator, and head end system. The system can include installing a regulator in a gas supply grid. The system may also include installing a gas meter in a gas supply grid, wherein the gas meter is installed to diagnose a grid pressure over flow rate of the regulator. In addition, the system may include determining, by the gas meter, an initial fingerprint of the regulator, wherein the initial fingerprint indicates an initial pressure and flow rate profile over a time period after the gas meter was installed. Further, the system can include comparing, by the gas meter, continuous pressure readings of the regulator with the initial fingerprint, wherein the gas meter determines if the continuous pressure readings correspond to the initial fingerprint. The system may also include notifying, by the gas meter, a head end system of the continuous pressure readings.

摘要： The system can include installing a gas meter in a gas supply net. The system may also include determining, by the gas meter, a level of pressure within the gas meter. The system may also include determining, by the gas meter, a flow rate level within the gas meter. The gas meter determines where a leak exists based on the flow rate level and the level of pressure. The system may also include determining, by the gas meter, a location of the leak, and whether the leak is upstream or downstream from the gas meter. The location of the leak is determined by the level of the pressure and the flow rate level. The system can also include a head end configured at a set position. The gas meter can inform the head end of the location of the leak.

摘要： Devices, methods, and systems for operating gas meters are described herein. The systems may include a gas measuring system connectable to a gas line, where the gas measuring system may include a flow rate sensor, a pressure sensor, and a controller in communication with the flow rate sensor and the pressure sensor. The flow rate sensor and the pressure sensor may be configured to sense measures of a gas passing through the gas line. The controller may repeatedly obtain pressure measurements at set pressure measurement times. Measures from the flow sensor may be monitored and when a measure from the flow sensor measure meets a flow rate criteria, the controller may trigger an extra pressure measurement without waiting for a next pressure measurement time. The controller may initiate closing of a gas valve when a measure from the pressure sensor exceeds a threshold value.

摘要： A static gas flowmeter for sensing a flow of gas includes an outer housing, a flow tube coupled to an outlet or an inlet, ≥1 sensor positioned for sensing gas flowing through the flow tube, and a controller including a memory including a flow calibration and flow measurement algorithm coupled to a sensor receiving a sensing signal. An integrated gas valve is connected to the inlet or outlet and/or there is an additional external valve positioned outside the housing coupled to the inlet to provide the gas flowmeter at least two state operation. Using the valve(s), the flow calibration algorithm triggers a zero-flow condition, then obtains a measured gas flow, and from the measured gas flow a flow offset is determined. If the flow offset is outside a predetermined limit, in-line calibrating is performed by adding the flow offset reflected as a correction factor to the flow measurement algorithm.

摘要： Devices, methods, and systems for operating gas meters are described herein. The systems may include a gas meter connectable to a gas line, where the gas meter may have a metrology unit in communication with a flow of gas through the gas line and an index unit in communication with and releasably coupled to the metrology unit. The metrology unit may be configured to generate flow rate data of the flow through the gas line based on outputs from a flow rate sensor, generate gas temperature data based on outputs from a temperature sensor, compensate the flow rate data based on the temperature data, generate an average flow rate, and output the average flow rate data to the index unit. The index unit may generate gas volume data based on flow rate data received from the metrology unit.
