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.

Abstract: A soil sampler includes a base and a plunger insertable into the base. The depth in which the plunger is inserted into the base determines the size of the sample collected by the soil sampler. The depth in which the plunger is inserted into the base can switch between a first size and a second size, allowing the user to collect different sample sizes using a single soil sampler. The soil sample that is collected can then be ejected from the soil sampler by shifting the plunger to an eject position relative to the base in which the plunger can shift further into the base to eject the soil sample.
