  • Patent number: 10786624
    Abstract: An apparatus for determining the volume of fluid dispensed. The apparatus has an acoustic volume sensor that acoustically excites a reference volume and a measurement chamber with a loudspeaker and measures the acoustic response with microphones acoustically coupled to the reference and the measurement chamber. The loudspeaker and sensing microphones are connected to the measurement chamber by separate ports. A detachable dispensing chamber is coupled to the acoustic volume sensor. The volume of the fluid dispensed is determined by a processor based on the acoustic response of the microphones to acoustic excitement by the loudspeaker.

  • Patent number: 9766636
    Abstract: A dilution control device and method of operating the same. The dilution control device can include a structure for dispensing concentrate and diluent fluid in a desired dilution ratio utilizing volumetric dosing. In some embodiments, diluent fluid drives a wheel or compresses a pliable concentrate bag in order to dispense concentrate in the desired ratio with the diluent fluid. In some embodiments, one or more floats can be used to drive a pump or actuate a valve to dispense concentrate at a particular rate proportional with the flow rate of the diluent fluid. In some embodiments, a rocker is responsive to the flow of diluent fluid to pump concentrate. In some embodiments, the dilution control device can be operable to automatically modulate the dispense rate of concentrate when the diluent fluid flow rate is varied in order to maintain a predetermined dilution ratio.

  • Patent number: 9636455
    Abstract: A pump, related system, and related method are provided. The pump includes a reservoir, a port, and a plunger. The reservoir delivers a liquid by discharging the liquid through the port coupled to the reservoir. The plunger has a piston coupled to a shaft and is disposed within the reservoir in sliding engagement with an inner surface of the reservoir. The piston defines a liquid side of the reservoir and a non-liquid side of the reservoir whereby movement of the plunger towards the liquid side of the reservoir discharges liquid through the port. The pump also includes a reference-volume assembly and/or a linear position sensor. The reference-volume assembly is coupled to the reservoir at an opposite end of the reservoir relative to the port and includes a reference-volume chamber in acoustic communication with the non-liquid side of the reservoir, a speaker disposed within the reference-volume chamber, and a reference microphone disposed within the reference-volume chamber.

  • Patent number: 9599252
    Abstract: A fluid flow control valve (101, 601) includes a housing (106) and a spherical obstructer (107) having a through hole (108), wherein the spherical obstructer (107) is inserted in the housing (106) and is adapted to rotate therein (106) about an axis of rotation (110) between a first position, in which the through hole (108) is substantially coaxial to the control valve to allow the passage of a fluid, and a second position, in which the through hole (108) is substantially transversal to the control valve to prevent the passage of a fluid. The control valve further includes a rotor (111) within the through hole (108), wherein the rotor is adapted to rotate in a continuous manner under the action of a fluid flowing through the control valve, rotating about a second axis of rotation (112) substantially coinciding with the axis of rotation of the spherical obstructer.

  • Publication number: 20150059866
    Abstract: The invention relates to a system for measuring cell turgor pressure (dendroturgometer), which can also operate as a firmometer. The system can also be used as an automatic dripper, wherein in this embodiment it is kept pressed by means of a flattening plate (1) against the organ (4), as well as by employing a brace (6) provided with a spring (5) that applies stable force of a magnitude higher than the product between the water pressure, regulated by a pressure adjuster (10) and the fluid layer (2) under the membrane (3), on which the plant exerts compression and obstructs the water flow. The dripping is started when the transpiration provides a drop in the cell turgor pressure of the plant, so that the resulting pressure will be lower than the adjusted water pressure. This system may also be miniaturized and used for measuring the vegetable turgor pressure by using water pressurization with an plunger (11).

  • Patent number: 8267108
    Abstract: A liquid metering device that dispenses liquid into an adjacent reservoir at a precise ratio relative to the total volume of the adjacent reservoir as the reservoir is filled with liquid. The hydrostatic dispensing system includes an additive reservoir, a calibrated dispensing vessel, a hydrostatic pressure chamber, and a three-way valve that passively arms and dis-arms the system. The precise dispensing of liquid by a calibrated dispensing vessel into the adjacent reservoir is accomplished entirely through the management and arrangement of hydrostatic pressure creating a liquid piston generated by the addition of liquid to the adjacent reservoir and its subsequent application to the liquid in the calibrated vertical column that displaces the calibrated volume of liquid into the reservoir at the same rate that liquid is added to the reservoir.

  • Patent number: 6216091
    Abstract: An ultrasonic measurement system performs a signal path measurement by directing ultrasonic signals through a gaseous material in a conduit, and processing the detected signals to determine sound speed and to derive the average molecular weight of an unknown hydrocarbon mixture present in the material. The processor includes a plurality of stored tables of critical constants of hydrocarbon mixtures as a function of the average molecular weight of the mixture, and is configured to iteratively set a hypothetical molecular weight, determine the corresponding critical properties, and compute a predicted sound speed. If the two speeds differ, a new weight is set and the procedure is repeated until the predicted sound speed matches the measured speed, indicating that the current estimate is the correct average molecular weight.
