A gas meter control system is adapted for use in gas meters having a plurality of different sizes (e.g., ability to measure different flowrates and/or different gas volumes per billing cycle) and different functional capabilities. In an example, the gas meter control system is configured to recognize and identify a metrology unit, sensor(s), switch(es), valve(s), valve motor(s), and/or other device(s) within a gas meter. Having identified devices present within a gas-environment and an air-environment of the meter, the control system selects and executes appropriate software to operate the identified devices. Addition of an additional component to the meter (e.g., an earthquake sensor or a tamper sensor) results in identification of the added component and execution of appropriate control software. Accordingly, the gas meter control system replaces a number of control systems configured to operate a single specific meter and/or configuration.

The invention relates to a fluid flow meter comprising a measuring section for a flow indicator with different measuring methods for flow velocity and fluid flow rate, comprising a housing with an inlet channel, an outlet channel and at least one flow indicator located therein, a housing interior space forming a shape which is complementary to the geometry of the flow indicator, and comprising two bottoms at least partially defining the interior space, and a curved part having a geometry that ensures the formation of a flow, at least one ultrasonic flow indicator being arranged such that the measuring section thereof runs through an inner part of the other flow indicator with another operating mode, and the fluid flow meter comprises an adaptor unit for adapting different diameters of an outlet of the flow indicator and the outlet channel thereof.

Illustrative embodiments of a meter box and couplings, either separately or in combination, are provided. An illustrative embodiment provides a valve coupling that is disposed through a wall of the meter box such that a first portion of the valve coupling extends exterior of the meter box and a second portion of the valve coupling extends interior of the meter box. An outlet coupling is disposed through the wall of the meter box such that a first portion of the outlet coupling extends exterior of the meter box and a second portion of the outlet coupling extends interior of the meter box. A telescoping tube is located in the meter box, extended into and movable relative to, and in fluid communication with, at least one of the second portion of the valve coupling and/or the second portion of the outlet coupling. The telescoping tube varies a distance between the valve coupling and the outlet coupling within the meter box.

An annulus pressure release system includes a gas metering valve assembly having a fluid pathway. The gas metering valve assembly includes a pressure sensor configured to be fluidly coupled to an annulus and to output a sensor signal indicative of a fluid pressure within the annulus. The gas metering valve assembly also includes an electronically actuated adjustable control valve disposed along the fluid pathway and a electronically actuated two-position valve disposed along the fluid pathway. Furthermore, the gas metering valve assembly includes a flow controller. The flow controller, in response to determining the fluid pressure exceeds a threshold pressure, is configured to output a first control signal to the electronically actuated two-position valve indicative of instructions to open the electronically actuated two-position valve, and to output a second control signal to the electronically actuated adjustable control valve indicative of instructions to adjust a flow of fluid through the fluid pathway.

The present disclosure relates to a crude oil flow metering device, which includes a measuring part and a metering part; the measuring part includes a measuring tube and a float assembly; the float assembly is in-built in the measuring tube, and includes a float and a float connection rod integrally connected with the float; an end of the float connection rod is connected to a detection part; the detection part protrudes out of the measuring tube when the float rises from a bottom end; the metering part includes a position detection module and a processing module; the position detection module is arranged in a detection cavity located above the measuring tube and formed by a first housing; when the detection part at the end of the float connection rod extends into the detection cavity, the position detection module detects a position of the detection part at the end of the float connection rod to obtain a float height detection signal; and the processing module calculates a flow rate of measured crude oil according to the float height detection signal.

A water management system effective for managing and metering water usage and detecting and reducing water leaks is described herein. The water management system can detect a leak when a volume of water flow or change in water pressure detected by a water meter of the system is uncharacteristic for a given day and time of day at the node. Upon detecting the leak, the system alerts the user, and in some situations, remotely shuts off a water supply to preemptively address a water leakage issue.

A method for forming a pressure fit hermetic seal between a second component (104) and an interior member (108) is disclosed. The method comprises steps of coupling the second component (104) to a first component (102) by applying heat to one or more of the first component (102) and the second component (104) and allowing the first component (102) and the second component (104) to cool, wherein the applying heat step and allowing to cool step form the hermetic seal by causing compression of a hermetic element (106) against the second component (104) and by causing compression of the hermetic element (106) against the interior member (108).

The present disclosure relates to a measuring tube for conveying a liquid, comprising a tubular section and at least one tubular branch for accommodating at least one component of a measuring device. A first end region of the tubular branch is arranged at or in an opening in a wall along a longitudinal axis of the tubular section. According to the disclosure all points of at least a first portion of the wall, such as an inner surface of the wall, of the tubular section, which first portion defines the opening, are located in a plane. Furthermore, the present disclosure relates to an arrangement for determining or monitoring at least one process variable of a liquid in a pipeline, comprising a measuring device and a measuring tube of the disclosure.

An adapter includes several connecting nozzles. Free nozzle ends of the connecting nozzles are adapted to be connected to line ends of fluid lines. The adapter includes, for guiding flowing fluid in and then out, two mutually separated, tubular flow channels. Moreover, the adapter includes a projection, which extends from the nozzle end with a length to a free projection end remote therefrom. A fluid line system formed by means of the adapter comprises, furthermore, a fluid line with, enveloped by a wall, a lumen. The fluid line can be connected with its line end to the connecting nozzle of the adapter in such a manner that the projection protrudes inwardly into the lumen of the fluid line to form two tubular chambers of the fluid line mutually separated by the projection and adapted for guiding through flowing fluid.
