Abstract: A system for monitoring an underground propane tank, comprising a controller; a moisture sensor coupled in communication with the controller, wherein the controller is configured to measure a moisture associated with the tank; a voltage probe coupled in communication with the controller, wherein voltage probe is adapted to be disposed at least partially underground, and wherein the controller is configured to measure a potential difference between the tank and soil surrounding the tank, when the moisture associated with the tank is measured to be above a predetermined threshold; and an anode sensor coupled to an anode of the tank and coupled in communication with the controller, wherein the controller is configured to monitor the anode using the anode sensor.

Abstract: A sensor arrangement for measuring liquid height in a tank can include a housing, a transducer, and a couplant. The housing can have an interior and an aperture, the aperture placing the interior of the housing in communication with the environment external to the housing. The transducer can be seated within the aperture. The couplant can be mechanically connected to the transducer and can have a compressible couplant body. The couplant body can extend between the transducer and the external environment for transmitting an acoustic pulse from the transducer to a tank bottom for measuring height of a liquid overlaying the transducer.

Abstract: An assembly for shipping, stocking and reordering merchandise comprises a container for receiving the merchandise, a label identifying the merchandise in the container, the customer to whom the merchandise is to be shipped and an order number, and a detachable reorder form which identifies the customer and the merchandise and provides a blank for filling in the quantity of merchandise to be reordered.
