  • Publication number: 20150083239
    Abstract: The double action float valve is connected to a single pipe and a tank and controls both the filling and discharge of the tank. The double action float valve utilizes a valve body, a heavy filling obturator positioned within the valve body, a light inverse obturator positioned within the heavy filling obturator, and a float connected to the heavy filling obturator. When the inflow pressure from the pipe is greater than the outflow pressure of the tank, the tank is filled until the float reaches a predetermined level. When the outflow pressure of the tank is greater than the inflow pressure, the double action float valve is automatically reconfigured to discharge the fluid from the tank into the pipe.

  • Patent number: 8960220
    Abstract: A liquid mass measurement and fluid transmitting apparatus includes a container for measurement of a mass of fluid therein. A sensor is coupled to the container which measures a mass of fluid within the container independent of variations of pressure within the container. A diaphragm sensor may be located on the bottom of the container whereby electrical signals representing the mass of fluid within the cylinder are created by movement of the diaphragm caused by the mass of fluid thereon. A pressure equalizer which equalizes the pressure within the container to the pressure on the opposite side of the diaphragm allows the measurement of the mass to occur independent of any variations and pressure within the container. Liquid within the mass of liquid within the container can be accurately measured such that a desired mass of liquid may be transmitted for further use. The liquid may be vaporized and transmitted as a vapor.

    Abstract: Piece of continuous operating cycle sludge transfer equipment, which consists of two deposits (D1-D2), each one of which has a filling or suction circuit and another emptying or discharge circuit. A vacuum pump (Depr.) creates a depression in the first of the deposits, which causes the product to be sucked up from the outside, until said tank reaches a certain set level. Meanwhile, the other deposit is pressurized by means of a compressor (Compr.) coupled to a driving circuit, independent from the vacuum, in order for said deposit to be emptied and the sludge discharged towards an output channel at the adequate distance and height. When the first device is filled, the valves in the suction circuit of said deposit close automatically and those in the emptying circuit open, whilst the filling circuit in the other device opens and the emptying circuit closes.

  • Patent number: 7614412
    Abstract: In the present washer fluid spraying apparatus, when the amount of the remaining washer fluid in the tank is reduced, the buoyant force of the float does not have an effect to the valve member, and therefore the cross-sectional area of the flow passage of the valve member is reduced. Consequently spraying amount is limited compared to a case where there is a plenty of amount of remaining washer fluid. Therefore, compared to the structure that controls the washer pump driving status by detecting the remaining amount by a sensor, the driver of the vehicle can know that the amount of the remaining washer fluid in the tank is reduced while limiting the manufacturing costs.

  • Patent number: 7477059
    Abstract: A level measurement device to measure the fill level of a fluid in a container, and a method to determine the contents level of a first fluid in a container and a presence of a second fluid below the first fluid. Microwave signals generated in the level measurement device are guided on a wave guide that is immersed in the first liquid. The measurement curve from received measurement signals is scanned for a first signal peak indicating a first fluid surface. The measurement curve is also scanned for a potential second signal peak having the same polarity as the first signal peak and thus indicating an interface between the first and a second fluid.

  • Publication number: 20080072968
    Abstract: An underground porosity reservoir includes substantially impermeable barriers and an aquiclude surrounding a volume of alluvial materials for storing water within the pore spaces of the alluvial materials. Upstream and downstream ends of the reservoir define both a static storage portion (extending below an elevation of the downstream end of the reservoir) and an elevated wedge-shaped portion that extends above the static portion. Once the static portion of the reservoir is filled, additional amounts of water are dynamically stored within the wedge portion by removing water from the downstream end of the reservoir and adding water to the upstream end of the reservoir. Water may be recirculated within the wedge portion, or external water may be added to the upstream end of the reservoir at a first flow rate while water is removed from the downstream end of the reservoir at a similar flow rate.

  • Patent number: 7028700
    Abstract: The present invention provides a method and apparatus for controlling a level in a receptacle capable of storing a fluid. The apparatus includes a first valve governing ingress of the fluid to the receptacle, a second valve governing egress of fluid from the receptacle, wherein the second valve is positioned below the first valve. The apparatus also includes a first switch deployed between the first valve and the second valve, wherein the first switch is capable of providing a first signal indicative of fluid at the first switch and a second switch deployed between the first switch and the second valve, wherein the second switch is capable of providing a second signal indicative of an absence of fluid at the second switch. The apparatus also includes a controller capable of controlling a fluid level in the receptacle by opening and closing the first and second valves responsive to the first and second signals.

  • Patent number: 6938635
    Abstract: The present invention comprises a novel level switch which may be employed to detect liquid levels within a process vessel. The level switch of the present invention is self validating so that manual testing is not required in order to ensure proper operation and switch calibration. The switch of the present invention may be easily introduced into existing process vessel designs as a replacement for prior art level detection switches with minimal or no retrofitting effort being required. The self validating level switch of the present invention may be connected to a Safety Instrumented System (SIS) such that process control including process shutdowns to avoid overfilling and low-fluid conditions may be accomplished.
