Abstract: A gas meter is outfit with near field communication (NFC) devices for in-situ exchange of data. The NFC devices reside in separate compartments. A first compartment houses electronics necessary to generate values for volumetric flow of material in a pipe. The gas meter includes a second compartment with an access point that allows data, including telemetry data, to transmit from the gas meter to a remote device. In operation, the NFC devices exchange data between the first compartment and the second compartment, often through a wall or barrier that prevents flow of fluid between the compartments.

Abstract: A magnetic sensor assembly for rotary gas meters includes a counter module electronic volume corrector (“EVC”). In one aspect, the assembly includes a magnetic sensor probe configured to be releasably secured within an aperture of a first gas meter body. The sensor probe may alternatively be positioned within an adapter sleeve. The adapter sleeve is configured to be releasably secured within an aperture of a second gas meter body. In another aspect, the counter module EVC includes a base coupling member, and the assembly includes first and second magnetic sensor probes, the probe being configured to be releasably secured within apertures of first and second gas meter bodies, respectively. Each probe has a probe coupling member that is releasably engagable with the base coupling member.

Abstract: A flow meter apparatus comprising: at least two magnets polarized in substantially opposite directions, mechanically coupled to a mechanical element mounted in a flow conduit and movable by a substance flowing through the flow conduit, for imparting movement from the mechanical element to the magnets, and at least two magnetic field sensors, each of the sensors deployed in a respective position next to the magnets, configured to sense a direction of a magnetic field in the position and to generate a signal indicative of the direction.

Abstract: An adapter assembly that works with a standard utility meter to wirelessly transmit data about consumption. The adapter assembly generates information about consumption by cooperating with a pointer of an index of a utility meter. In some embodiments, the adapter assembly includes an upper portion and a clip that interface together. The upper portion and the clip are configured to maintain alignment with the pointer and not create stress on the index.

Abstract: A metering system for measuring a flow of petroleum and LPG. In embodiments of the invention, a magnetic drive is used to couple a measuring chamber, such as a known oscillating piston system, to a register or indicator, avoiding leakage and excessive wear due to passing a shaft through the wall of the chamber.

Abstract: A meter for flowing material, e.g., water, has a meter register having an electronic display, e.g., an LED or LCD display, and a mechanical read-out display driven by a stepper motor to record units of water that flowed through the meter. In the event of an electrical power failure, the LED or LCD readout values are lost, however, the mechanical read-out values remain. Further, signals are transmitted to a microprocessor of a meter register to change the rotation of the stepper motor so that the meter register can be used with different types of meters. Still further, a meter generator co-acting with a meter register forwards an electrical pulse signal after a quantity of material or utility passes through a water meter to a microprocessor of a remote reader. The remote reader includes an odometer coupled to a stepper motor.

Abstract: A fluid meter. An illustrative embodiment of the fluid meter includes a meter housing having a housing interior, a rotatable paddle provided in the meter housing and a counter coupled to the paddle.

Abstract: A liquid dispenser comprises a sprayer device and volume meter connected together to form an integral unit that prevents the sprayer device and volume meter from being disconnected without damaging the dispenser. The volume meter has an inlet end portion and a gauge member downstream of the inlet end portion that responds to liquid flowing through the dispenser to provide a visual readout indicating the volume of liquid flowing through the dispenser. A common passageway extends through the sprayer device and volume meter through which liquid flows from the inlet end portion of the volume meter, past the gauge member, and exits the sprayer device at a head end thereof.

Abstract: A tracking assembly and method for tracking the operation of a rotary gas meter that has a driven member includes a connecting member, a gear assembly and a mechanical counter. The connecting member is adapted to be coupled to the driven member. The gear assembly is adapted to be coupled between the connecting member and the mechanical counter. The mechanical counter is used to count a value that is directly proportional to the number of rotations of the driven member when the connecting member is coupled to the driven member. The value provided by the mechanical counter is multiplied by a conversion factor such that the associated volume of gas displaced by the gas meter can be determined.

The systems and techniques may include a meter index cover and a wireless meter transmitter adapter. The meter index cover may be configured and arranged to house a meter index and include a mounting member configured and arranged to couple to a variety of wireless meter transmitter adapters. The wireless meter transmitter adapter may be configured and arranged to couple to the mounting member and to couple to a wireless meter transmitter.

Abstract: The mass flow of hydrogen fuel in the anode loop of a hydrogen fuel cell is measured using a rotating flow meter. The flow meter includes a bladed rotor mounted for rotation within a tube disposed in the stream of hydrogen fuel flowing through the anode loop. A magnetic sensor senses changing magnetic field caused by the rotation of the rotor and produces an alternating signal having a frequency related to the rotational rate of the rotor, and thus of the mass flow rate of the hydrogen fuel. A fuel purity sensor increases the accuracy of the mass flow measurement by determining the concentration of foreign substances contained in the fuel.

Abstract: A water purifier 40 includes a flow meter 42 for measuring the cumulative flow of water through a water purification cartridge 6. The flow meter has an indicator portion 44 that rotates in response to increasing cumulative flow and a graduated portion 46 rotating about the same axis as that of the indicator portion. The graduated portion includes an insertion groove 29 for manually rotating the graduated portion in order to reset the flow meter. Because the flow meter has few part, the body of the water purifier can be made compact and its cost reduced.

Abstract: A scale indication apparatus and a flow meter having the scale indication apparatus, which improve the usability and the versatility. The scale indication apparatus (31) is rotatably attached to a measurement apparatus (1) which can not be externally operated and indicates a scale when reading the displacement magnitude of an indicator (19) of the measurement apparatus (1). A scale indication position can be sequentially moved to reset the displacement magnitude of the indicator (19) by the rotating operation in a first direction without movement in an axial direction, and the scale indication apparatus (31) can be moved in the axial direction to be detached from the measurement apparatus (1) by the rotating operation in a second direction opposite from the first direction.
