摘要： 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.

摘要： A pneumatically driven fluid pump apparatus is disclosed which includes a pump casing having an inner wall, a pump cap secured at a first end of the pump casing, and a liquid discharge tube in communication with the pump cap and extending at least partially within an interior area of the pump casing toward a second end of the pump casing, and where fluid is admitted into the pump casing at the second end. The pump cap has an airflow inlet for receiving a pressurized airflow from an external pressurized air source, which helps displace liquid collecting within the pump casing upwardly through the liquid discharge tube. A flow channeling subsystem is in communication with the airflow inlet and directs the pressurized airflow towards the inner wall of the pump casing to create a swirling airflow within the pump casing that extends along at least portions of the inner wall. The swirling airflow entrains fluid within the pump causing the fluid to move in a circumferential swirling fashion toward the second end of the pump casing, which helps to clean the inner wall of the pump casing.

摘要： The present disclosure relates to a fluid level sensing system for sensing a fluid level in a well. The system has an upper housing in communication with a lower housing, with the lower housing having a first bore in communication with a fluid in the well, and a second bore isolated from the first bore and in communication with at least one of a vacuum gauge or an external vacuum source. The upper and lower housings house a first flexible bag and a second flexible bag, with the first bag housed within the second bag. A portion of the first bag communicates with the first bore and is responsive to a change in pressure within the first bore caused by a changing fluid level in the well. A portion of the second bag communicates with the second bore and exerts a reference pressure on the first bag. A sensing subsystem senses expanding and contracting movement of the bags and generates a signal indicative of a change in a level of the fluid in the well.

摘要： The present disclosure relates to a flow turning system for imparting a rotational, swirling motion to a fluid flowing through the flow turning system. The system may comprise a housing and a flow turning element supported within the housing. The flow turning element may have a plurality of circumferentially spaced vanes projecting into a flow path of the fluid as the fluid flows through the flow turning system. The vanes impart a swirling, circumferential flow to the fluid to help prevent contaminants in the fluid from adhering to downstream components in communication with the flow turning system.

The pressurized airflow causes a swirling flow of the liquid within the interior area of the pump casing that helps to clean the interior area of the pump casing by liquid scrubbing action to dislodge debris adhered within the interior area of the pump casing and remove the debris up through the liquid discharge tube and out from the fluid pump apparatus during a liquid eject cycle

摘要： 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.
