Abstract
The present invention is a device and method for monitoring the amount of paint or beads being applied by a paint truck to a road or other surface. Paint and/or bead storage tanks are mounted on weigh bars. By taking periodic measurements of the weight of the storage tanks and by correlating that data with the distance of the road or other surface painted, an operator is able to ensure that the amount of paint and/or beads being applied is within a desired specification.
Claims9
A method for applying a pavement marking material and beads to a roadway, comprising:
- providing at least one first tank for the pavement marking material,
- weighing the pavement marking material and generating a first electronic signal representative of the weight of the pavement marking material in the first tank at a first time point and at a second time point different from the first time point;
- providing at least one second tank for the beads,
- weighing the beads and generating a second electronic signal representative of the weight of the beads in the second tank at a first time point and at a second time point different from the first time point;
- providing the first and second electronic signals to a microprocessor;
- displaying an output of the processor on a display device.
A method for monitoring the amount of material being applied to a surface, comprising:
- providing at least one first tank containing a pavement marking material;
- weighing the first tank with at least one weigh bar under the first tank to determine the weight of the pavement marking material therein;
- generating a first electronic signal representative of the weight of the pavement marking material in the first tank at a first time point and at a second time point different from the first time point;
- providing at least one second tank containing reflective beads;
- weighing the second tank with at least one weigh bar under the second tank to determine the weight of the beads therein;
- generating a second electronic signal representative of the weight of the beads in the second tank between the first time point and at the second time point;
- generating a third electronic signal representative of the amount of pavement marking material and beads applied to roadway between the first time point and the second time point;
- transmitting the first, second and third electronic signals to a processor;
- and
- displaying an output of the processor on a display device.
