Abstract: 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.

Abstract: 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.

Abstract: A system includes a flow tube configured to receive a flow measured by an ultrasonic flow measurement, wherein a center region of the flow tube is configured to have a drop in pressure. The system also includes a heat source/hot wire and temperature sensors configured to enable a flow measured by a thermal massflow measurement. In the system, a controller is configured to compare the flow measured by the ultrasonic flow measurement to the flow measured by the thermal massflow measurement. The controller determines a ratio of the flow measured by an ultrasonic flow measurement to the flow measured on by the flow measurement based on thermal massflow. The controller also calculates a density, a thermal conductivity and an energy and/or gas content of the gas.

Abstract: 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.

IPC: G01F1/66
Abstract: Methods and systems for flow measurement can involve calculating an absolute-time-of-flight with respect to a flow of a fluid in a flow channel by reflected signals, reflected and unreflected signals, or a pulse train, determining a delta-time-of-flight with a cross correlation of two signals with respect to the flow of the fluid in the flow channel, and calculating the flow rate of the flow of the fluid in the flow channel based on the absolute-time-of-flight and the cross correlation of the delta-time-of-flight.

Abstract: A method and system for measuring a time of flight can involve correlating a signal comprising a reflected signal from a first transducer to a second transducer, or a subsequent reflected signal at the first transducer or the second transducer, with a previously received signal to produce a correlation for a measurement of a time of flight. The signal(s) can include one or more of a pulse train, acoustic sound; ultrasonic sound; or light, and the previously received signal can be a signal that has been reflected one or more times.
