A side view fluid meter counter assembly comprises a mounting bracket to mount a mechanical counter to an end of a fluid meter (e.g. gas meter) and a drive mechanism to drive a counter shaft of the mechanical counter from rotational movement of a rotationally driven member of the fluid meter. The rotationally driven member has a drive shaft extending in an end facing direction to connect to the drive mechanism and the mounting bracket mounts the mechanical counter in an orthogonal direction to the end facing direction such that a face of the mechanical counter is viewable from a side of the meter. The drive mechanism may comprise a worm drive. The drive mechanism may further comprise a pair of bevel gears. The mounting bracket further mounts the drive mechanism. Further provided is a fluid meter having a side view counter.

An apparatus has a housing with a fluid inlet in fluid communication with a fluid flow path, and a fluid outlet. The monitor includes a controllable valve and a diverter that accommodates different types of sensors. The housing includes a dry housing interior fluidly isolated from the fluid flow path. The monitor includes a power generator configured to generate a voltage when fluid flows through the fluid flow path and at least one sensor configured to measure at least one characteristic of a fluid flowing through the fluid flow path. The monitor includes a signal generator configured to transmit signals from the power generator and from the at least one sensor to a remote processor. The power generator is configured to power both the at least one sensor and the signal generator in response to fluid flow through the fluid flow path.

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.

A flow meter system for detecting the flow of a fluid between an inlet and an outlet. A top plate is coupled to the inlet and the outlet and a sensor is configured to detect the fluid flowing therebetween. A main module is coupled between the inlet and the outlet and has a main rotor configured to be rotated by the fluid flowing through the main module. An output shaft is coupled to the main rotor such that rotation of the main rotor causes rotation of the output shaft. A first spacer is removably coupled between the main module and the outlet. The first spacer is rotorless. The top plate defines an opening that receives the output shaft. The first spacer ensures alignment between the output shaft and the opening defined in the top plate. The sensor senses rotation of the output shaft to detect the flow of fluid.

An autonomous, low-power turbine flow meter and an assembly of at least one flow meter and at least one signal receiving device configured to receive signals, preferably in a wireless manner, produced and transmitted by the flow meter. The invention further relates to a method for measuring at least one flow characteristic, in particular the flow rate, of a fluid flowing through a flow meter.

A portable air flow meter fabricated using a 3D printer. A nozzle cover, a fixing cover, and a handle are formed integrally with a cylindrical housing in which a multi-nozzle for measuring an air flow is installed. The cylindrical housing is fabricated using a 3D printer. Fabrication costs are reduced, and a fabrication period is reduced. The portable air flow meter has superior portability due to light weight, and is effective in terms of usability.
