  • Patent number: 10954115
    Abstract: A system for delivering fuel to an equipment fuel tank. The system includes a remote fuel storage tank and a valve assembly coupleable to the equipment fuel tank. The system includes a fuel supply line extending between the remote fuel storage tank and the valve assembly and a pneumatic valve disposed in the fuel supply line. The pneumatic valve can prevent flow of fuel into the fuel supply line or can enable flow of fuel into the fuel supply line. The valve assembly includes pressure tubes to detect changes in fuel level inside the equipment fuel tank. A switch actuates the pneumatic valve to prevent the flow of fluid in response to an overfilled position; and actuates the pneumatic valve to enable the flow of fluid in response to an underfilled position.

  • Patent number: 7047806
    Abstract: The present invention provides a liquid level gage and an illuminator therefor. One embodiment of the liquid level gage includes a housing, a liquid column, an illuminator, and a power supply. The housing has a first or front end and a second or rear end. The liquid column includes a plurality of liquid column bodies connected to the front end of the housing. The liquid column also includes a first or front port assembly and a second or rear port assembly connected to each liquid column body. The liquid column is connected, either directly or indirectly, to a vessel. The illuminator includes a plurality of directed light source assemblies connected to the rear end of the housing. Half of the directed light source assemblies emit a first color light and half of the directed light source assemblies emit a second color light. A pair of bi-color directed light source assemblies (i.e.

  • Patent number: 4074577
    Abstract: An assembly is provided for taking a sample from a desired level in a tank, including at least one tube extending from the outside of the tank to a selected level in the tank from where a sample is to be taken. The inner end of the tube is in fluid communication with a sampling chamber. The sampling chamber has an opening in its lower portion in communication with the inside of the tank through which liquid from the tank to be sampled may enter. The outer end of the tube is provided with a sampling valve for removing a sample from the tube. When the tank is not loaded, air enters the sampling chamber and the tube from within the tank and/or from the outside of the tank when the sampling valve is opened. The sampling valve is closed prior to loading the tank. The sampling chamber and the tube are sized such that the air pressure in the tube and in the sampling chamber prevent the liquid from entering the tube when the tank is filled.

  • Patent number: 4008612
    Abstract: A liquid quantity detecting device comprises a liquid container, liquid circulating means disposed within the liquid container, and means for detecting bubbles created by the liquid circulating means when the liquid level has been lowered. Thus, decrease in quantity of liquid may be detected in accordance with the detection signal from the detector means.
