  • Publication number: 20210199001
    Abstract: A fluid level sensor system is disclosed for sensing a fluid level in a well. The system has a main body and an inlet housing coupled to the main body. The inlet housing has an internal chamber in communication with an ambient environment within the well. A bellows within the main body communicates with the internal chamber of the inlet housing. A movable element is responsive to movement of the bellows. A sensor detects when the movable element moves from a first position, indicating a first fluid level in the well, to a second position indicating a second fluid level within the well. An indicator is operably associated with the movable element and moves into a position to be viewable when the sensing element is moved to the second position, to provide a visual indication that the second fluid level has been reached.

  • Patent number: 10974276
    Abstract: A system that reduces the amount of water that enters a process chamber via a movable shaft is disclosed. The surface of the shaft is made hydrophobic. Any water droplets that are collected on the hydrophobic shaft are disposed at a high contact angle, making it more likely that these water droplets fall from the shaft. Further, any water that enters the process chamber is more readily removed from the shaft due to the lower energy of liberation. Reducing the amount of water in a process chamber may improve the lifetime of the components in the process chamber and may improve the yield of the workpieces being processed. This may be especially relevant when process gasses that contain halogens are employed.

A magnet housing may be included which is moveable linearly within the bore of the main housing in response to the pressurized fluid signal entering the bore. A magnet may be secured to the magnet housing. A switch housing may be included which is operably associated with the main housing and which includes first and second longitudinally spaced apart sensing components. The sensing components are used to detect movement of the magnet in response to the pressurized fluid signal.

  • Publication number: 20200309114
    Abstract: The present disclosure relates to a pneumatically driven fluid pump apparatus having an outer pump housing for collecting liquid to be pumped, and a valve assembly in communication with liquid admitted through an inlet end of the outer pump housing and collecting within the outer pump housing. The valve assembly includes a housing assembly and a poppet valve assembly disposed within the housing assembly to act as a one-way check valve when pumping collected liquid out from the outer pump housing. The poppet valve assembly includes a poppet valve component including a relief area that helps to depressurize an interior area of the valve assembly, to facilitate rapid movement of the poppet valve element from an open position toward a closed position, when only a pressurized fluid flow being used to eject the collected liquid is flowing past the poppet valve component.

  • Publication number: 20200263706
    Abstract: Various embodiments concern a pneumatic landfill pump cycle counter comprising a spring located within a housing passage and a shuttle comprising a shuttle magnet, the shuttle located within the passage. The shuttle can be configured to move axially by the spring within the passage in an upstream direction to a home position, move axially by one or both of air pressure differential and airflow within the passage in a downstream direction away from the home position to a hold position. The cycle counter can further comprise a counter comprising an element responsive to a magnetic field of the shuttle magnet, the counter configured to increment a numeric count for each complete cycle of the shuttle moving from the home position to the hold position and then back to the home position.
