  • Patent number: 10317267
    Abstract: Systems, methods, and devices relating to the determination of a volume of liquid in a container. A pressure sensor is located at a bottom of the container. The pressure sensor senses the pressure exerted on it by the liquid in the container. This pressure is communicated with a data processing device. The data processing device determines the volume of the liquid in the container based on the sensed pressure. This may be done by reference to a look up table containing pressure values and their corresponding volumes. Similarly, this may be done by calculating the volume of the liquid based on the dimensions of the container, the physical qualities of the liquid, and the sensed pressure. The volume of the liquid in the container is then transmitted from the data processing device to a user interface device for presentation to a user.

    Abstract: Appurtenances added to a pipe mitigate the effects of upstream valves, sluice gates or pipe elbows to condition the pipe flow for accurate flow rate detection by a reverse propeller meter. Further appurtenances allow the reverse propeller meter to be used in extreme debris situations such as weeds, vines and moss present in many canal systems. The system provides an electronic signal that indicates flow rate and accumulated flow volume, or the signal can be transmit to a central headquarters for remote gate control or canal automation.

  • Patent number: 8413502
    Abstract: Devices, systems and methods for measuring infant feeding performance. The device includes a body portion, a pressure sensor and an integrated circuit. The body portion includes a first end for receiving a fluid, a second end mateable with a feeding nipple, and a conduit in fluid communication with the first and second ends. The pressure sensor is disposed in the body portion, is in contact with the fluid in the conduit, and generates a signal representing a pressure of the fluid passing through the conduit during a feeding session. The integrated circuit is disposed in the body portion and is electrically connected to the pressure sensor. The integrated circuit receives the pressure signal and determines a feeding factor over the feeding session indicative of the infant feeding performance.

  • Patent number: 8306762
    Abstract: Systems and methods for analysis of data associated with fluid flow through a conduit and potential control of the fluid flow. In one embodiment, a method includes a data processing unit obtaining from a sensor a signal representing a series of measurements of a physical parameter associated with fluid flow through the conduit. The data processing unit performs singular spectral analysis of this signal and thereby identifies recurring, possibly non-sinusoidal patterns in the signal. The data processing unit may construct a second signal from some or all of the recurring patterns identified in the first signal. Alternatively, the data processing unit may identify recurring patterns in the signal which are indicative of corresponding conditions associated with the fluid flow through the conduit. The data processing unit may then initiate control functions responsive to the recurring patterns and associated conditions.

  • Patent number: 8302470
    Abstract: A flow test device for diminishing and diverting the flow of a high pressure stream of water while testing a fire pump has a hollow diverter tank supported on a trailer for receiving a high pressure stream of water forced by the fire pump through one or more pipes and nozzle tips retained in a stable position adjacent the diverter tank. Diffusers within the tank divert the flow of water as it enters the tank with the water subsequently exiting through an open bottom of the diverter tank. One or more support panels maintain the pipes in a generally horizontal orientation in relation to the diverter tank. A valve and gauge board enables a user to control the testing and provides for easy positioning in the vicinity of the fire pump to be tested while avoiding splash and spray from the diverter tank discharge.

  • Publication number: 20120216609
    Abstract: The present disclosure relates to a method for determining the delivery rate of a liquid conveying device, in particular a concrete pump, wherein on the basis of measured values concerning the pressure of the liquid the number of the pump strokes of the concrete conveying device is determined, in particular substantially calculated, by series-connection of a plurality of filters with adaptive filter length and variable detection limits. Furthermore, the present disclosure relates to a liquid conveying device and to a construction vehicle with a liquid conveying device.

  • Patent number: 8181512
    Abstract: A timing device includes a timer and a flow meter mounted on the timer. The timer has a water inlet port and a water outlet port. The flow meter includes a first guide pipe mounted on the water outlet port and provided with a mounting chamber, a detector mounted on the first guide pipe, a rotation ring rotatably mounted in the mounting chamber, a magnetic member mounted on the rotation ring and movable to pass the detector, and a second guide pipe mounted on the first guide pipe. Thus, the water flow rate in the flow meter is calculated according to the times of the magnetic member passing the detector so that when the flow rate of the water passing through the flow meter reaches a preset value, the timer stops operating so as to control the water flow exactly.

  • Publication number: 20120079880
    Abstract: A fluid flushing and pressurization apparatus for use with geothermal systems, capable of delivering a reversible high-velocity flow of fluid through a system of buried PE pipe without introducing an overpressure condition or water hammer. The apparatus can be utilized with methods for installing, preparing, flushing, filling, testing, and certifying geothermal heating and cooling systems. A portable pumping and testing apparatus can include a high-volume pump, a high-pressure pump, a flow meter, and pressure sensors in wired or wireless communication with a processor or logic controller such that continuous or periodic monitoring of the system can be recorded. The system can be programmed to operate automatically under computer control such that reversal of the flow through the geothermal system does not shock or damage the equipment or buried piping.
