Abstract:
A device for measuring and monitoring the volume of a liquid in a container mounted in a movable vehicle, said device comprising:a mounting adapter for mounting said device in a top wall of the container;a beam attached to said adapter;a pair of strain gauges disposed on said beam;a longitudinal buoyant element with one end affixed to said beam and a free end extending into the container, said buoyant element adapted to be partially submerged in a liquid in the container such that upward and downward movement of said buoyant element registers on said strain gauges as corresponding strain measurements, said strain gauges disposed on said beam and relative to one another to offset torsional and lateral forces on said buoyant element due to movement of the liquid in the container;a processor coupled to said strain gauges for correlating strain measurements by said strain gauges to the volume of liquid in the container; andan output component coupled to said processor for indicating the measured volume of liquid in the container.
