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.
