1. A system comprising:
- a first feeder configured to move asphalt;
a hopper configured to receive the asphalt from the first feeder;
a second feeder configured to move the asphalt out of the hopper;
at least one non-contact sensor configured to sense the asphalt in the hopper;
a controller configured to receive a signal from the at least one non-contact sensor and control the first feeder and the second feeder to control the amount of asphalt in the hopper based on set parameters of minimum and maximum amount limits; and
an inclination sensor configured to sense an inclination of the hopper about at least two axes and send a signal to the controller, wherein the controller is configured to calculate the level of asphalt within the hopper based at least partly on the signal from the inclination sensor and determine an amount of asphalt within the hopper based on the signal from the at least one non-contact sensor.

10. A method comprising:
-
moving asphalt to a hopper using a first feeder and moving the asphalt out of the hopper using a second feeder; sensing asphalt within the hopper using at least one non-contact sensor; sending a signal from the at least one non-contact sensor to a controller; controlling the first and second feeders based on output from the at least one non-contact sensor to keep the amount of asphalt in the hopper between a minimum amount and a maximum amount; sensing an inclination of the hopper about at least two axes using an inclination sensor and sending a signal to the controller; and calculating a level of asphalt within the hopper based at least partly on the signal from the inclination sensor. - View Dependent Claims (11, 12, 13, 14, 15, 16)
