Detection of Slurry Flow State in Slurry Wagon Hoses

Precision application of slurry requires knowledge about the delay time between the sending of the turn-on command and the slurry beginning to be applied on the ground. Most systems use a fixed delay time, regularly calibrated by the farmer. This paper presents the design of a sensor to detect when slurry is flowing and thus detect the delay time. Such a system is useful for studying the quality of Task Controller Section Control (TC-SC).
