ABSTRACT:
This invention relates to apparatus and methods for measuring height variations on a floor surface to test for floor flatness sufficient for automated high level warehousing applications. An inclinometer mounted on a trolley set to follow a reference line produces signals indicative of the floor profile. A computer samples the sensor output at selected intervals and calculates floor height at the data points relative to a reference level. The floor profile data may be stored for subsequent use or it may be printed to form a plot or graph of the floor profile along the reference line.
