  • Publication number: 20220146297
    Abstract: A multifunctional dust trap for reducing an acoustic noise and dust filtering comprising: an inlet connected to a gas inlet of a gas meter; a chamber, connected to the inlet, to receive a flow of a gas, comprises: a first wall to deflect the flow of the gas in a first direction, wherein the first wall directs the flow of the gas into a cross sectional area of the chamber, which reduces a velocity of the deflected gas such that a centrifugal force guides a plurality of dust particles towards a base of the chamber; and a second wall to deflect the flow of the gas in a second direction; and an outlet, attached to the chamber, to enable an exit of a clean flow of the gas away from one or more flow inlets of a flow tube installed within the gas meter.

  • Publication number: 20220136875
    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.

  • Publication number: 20220136879
    Abstract: Disclosed is an ultrasonic flow tube comprising: a flow chamber for accepting an inflow of a gas, comprising a center pipe and a plurality of outer pipes surrounding the center pipe, connected between an inlet wall and an outlet wall of the flow chamber such that a velocity of the gas within the center pipe and the plurality of outer pipes is numerically same; and a first transducer attached near the inlet wall and a second transducer attached near the outlet wall, wherein a first acoustic wave package generated by the first transducer and a second acoustic wave package generated by the second transducer is transmitted into the flow chamber such that the center pipe receives a majority of the first and the second acoustic wave package, and the plurality of outer pipes receives a minority of the first acoustic wave package and the second acoustic wave package.

  • Publication number: 20220136926
    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.

  • Publication number: 20220049986
    Abstract: 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.

  • Publication number: 20210396331
    Abstract: A valve without position indicating switches. Positions of the valve are detected from current magnitude measurements and current profile analytics. The current profile may be learned initially and relearned and adapted at each operation. The valve may be opened and closed by a driver that is actuated by an electrical current to control the opening and closing of the valve. The current may be regulated by a controller to open and close the valve appropriately.

  • Publication number: 20210381864
    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.

  • Publication number: 20210381863
    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.
