Abstract
The present invention relates to the use of a solid material flow meter which utilizes a friction pad thermally connected through a thermal path of known thermal characteristics to a heat sink. Temperature sensors are positioned along the thermal path to sense the flow of heat from the friction pad to the heat sink when solid material, such as soil, is flowing in contact with the pad. An electrical signal output proportional to relative soil volume flow rate is derived from heat sensor output multiplied by depth and width of cut. The output (1) indicates when and if soil is flowing along the friction path into a bowl, and (2) indicates the optimum and unique peak rate at which it is possible for the pan scraper bowl to be loaded.
