Embodiments provide a fluid metering device, including: a first fluid supply port for receiving a first fluid; a first fluid dispense port for dispensing the first fluid; a second fluid supply port for receiving a second fluid; a second fluid dispense port for dispensing the second fluid; a waste discharge port for discharging a mixture of the first fluid and the second fluid; a valve assembly including a plurality of valves; a manifold connected to the metering pump, wherein the manifold includes a plurality of fluid channels, and the manifold is used for communicating between the valve assembly and each port; a first tube connected between the second valve and the third valve for accommodating the mixture or the first fluid; and a second tube connected between the third valve and the fourth valve for accommodating the second fluid.

A volume fraction meter that includes a flow meter coupled to a flow line. The flow line includes a turned portion and the flow meter is positioned upstream from the turned portion with respect to a flow direction. The flow meter is configured to measure a volumetric flow rate of a multiphase fluid flowing in the flow direction through the flow line. The flow line includes a nozzle opening downstream the turned portion. The volume fraction meter also includes a strain gauge coupled to the flow line between the flow meter and the turned portion of the flow line. The strain gauge is configured to measure a bending strain on the flow line upon discharge of the multiphase fluid through the nozzle opening, such that the bending strain and the volumetric flow-rate provide inputs for determining a mixture density of the multiphase fluid.

A personal flow meter for measuring water consumption of an individual has a housing, inductors attached to the exterior of the housing and a rotatable member disposed within the housing. A front cover and rear cover are attached to the housing. The front cover includes a fluid inlet having an angulated internal fluid channel that causes water to enter the housing at an angle. The rear cover has a fluid outlet to allow egress of water within the housing. The rotatable member includes angulated fins. Water entering the housing via the internal fluid channel perpendicularly strikes the fins to initiate rotation of the rotatable member. Magnets are attached to the rotatable member in an alternating magnetic pole arrangement. Rotation of the rotatable member causes the inductors to generate voltage signals. Electronic circuitry processes the voltage signals and generates signals that represents the individual's water consumption over a period of time.

A flow meter has a meter wheel housing connectable in-line in a liquid conduit such that liquid flows through the meter wheel housing from an input port to an output port. Liquid flowing from the input port to the output port rotates a meter wheel mounted in the housing, and a wheel sensor measures rotational speed of the meter wheel. A first jet member defining a first orifice with a first cross-sectional area is movable into a jet operating position between the upstream end of the liquid conduit and the input port such that liquid passes through the input port into the meter wheel housing only through the first orifice. A second jet member defining a second orifice with a second cross-sectional area is movable into the jet operating position. The second cross-sectional area is less than the first cross-sectional area.

A system and method determines an amount of water and water flow rate in a water dispenser system including a container/bottle, using a strain gage device(s) mounted on a structure or plane in relationship to the container/bottle. One or more strain gages are configured in a position to measure force per unit area, exerted by a portion of the water container/bottle in a normal or direction substantially perpendicular to a surface or plane on which the strain gage device(s) are mounted. The portion of the container/bottle is positioned in direct or indirect contact with the one or more strain gages to produce a strain gage signal representative of the amount of water in the container/bottle and periodic sampling of the strain gage signal is representative of flow rate of water from the container/bottle. Signals from the strain gage(s) are processed in a manner that allows the amount and rate of consumption of water to be monitored and determined automatically on-site or remotely.
