Abstract
A landfill pump cycle counter includes a housing defining an internal passage, a poppet disposed within the internal passage, a magnet disposed within an internal cavity of the poppet, a counter, a seat formed on an inner surface of the housing, and a mating surface formed on the poppet. The landfill pump cycle counter is configured to receive liquid output from a landfill pump. The housing extends along an axis and also defines an inlet and an outlet. The internal passage fluidly connects the inlet to the outlet. The poppet is configured to be moved axially between an open state and a closed state. The counter includes a magnetic sensor configured to detect a poppet cycle. The poppet cycle includes the poppet moving from one of the open state and the closed state to the other of the open state and the closed state.
