Abstract: A sensor unit that is configured to improve the non-contact, magnetic interface on a gas meter. The configurations may include a pair of magnets that co-rotate in response to a magnet internal to the gas meter. At least one of the magnets may also move longitudinally in proximity to the internal magnet. This feature aligns the magnets with one another to ensure proper magnetic coupling with the internal magnet.

Abstract: A manifold assembly configured to measure differential pressure of fluid. The manifold assembly may have a monolithic body with an internally drilled fluid pathway. The body supports a differential pressure transducer that communicates, on either end, with the internally drilled fluid pathway. This configuration can generate data that defines pressure drop across impellers or other mechanisms on metrology hardware (or “gas meters”). Utilities can use this data to diagnose health or other conditions on the gas meter in the field.

Abstract: A gas meter (100) and like metering systems that are configured for use underwater. The gas meter may embody a positive displacement rotary gas meter having a meter body with impellers that counter-rotate in response to material flow. The gas meter can also comprise an index unit having an electronics assembly to generate a value that equates rotation of impellers with a parameter of the material flow. The gas meter can further comprise a connective interface having a first part and a second part, one each disposed on the meter unit and the index unit, respectively, the first part and the second part coupling with one another to provide data to the electronics assembly, the data corresponding with operating conditions on the meter unit and rotation of the impellers. In one example, the first part and the second part are configured so that the meter unit and the index unit are operable underwater to generate the value.

Abstract: A power generator for use to generate power for metrology hardware like gas meters and flow measuring devices. The power generator may use flame-less combustion that creates heat from fuel gas. The heat causes a temperature differential. The power generator may include a thermal electric generator that generates an electrical signal in response to the temperature differential.

Abstract: An energy harvester for use to provide power to metrology hardware like gas meters and flow measuring devices. The energy harvester may include an actuator that mounts to a substrate found in the gas meter or in an adjacent, collateral device like a pressure regulator. The substrate may embody a diaphragm or membrane, possibly a thin, flexible or semi-rigid member. The actuator may include piezoelectric transducers that mount to this member. In operation, the piezoelectric transducers can generate an electrical signal in response to mechanical activity (or energy) from the thin member. The electrical signal can be directed to the flow device to replace, supplement, or recharge a power source that powers electronics necessary to expand functions on the flow meter.

Abstract: Wellbore sensor systems and related methods are disclosed. A wellbore sensor system includes a first sensor node and a second sensor node. The first sensor node is operably coupled to a drill string at a first location. The second sensor node is operably coupled to the drill string at a second location. A method includes taking first sensor readings from the first sensor node relative to a first spatial frame of reference, and taking second sensor readings from the second sensor node relative to a second spatial frame of reference, and using the first sensor readings and the second sensor readings to estimate parameters of a mathematical transform configured to transform the second sensor readings into the first spatial frame of reference. The method also includes transforming the second sensor readings into the first spatial frame of reference with the estimated mathematical transform.
