APPLICATION RATE MONITORING DEVICE

摘要

An application rate monitoring device to determine and display the volume of liquid or granular material applied per unit area by mobile application equipment is described. The device includes a first measuring means which generates electrical pulses having a frequency proportional to the rate at which the application equipment covers a unit of area and a second measuring means which generates electrical pulses having a frequency proportional to the rate of application of the material. A frequency multiplying means operates on the electrical pulses of the second measuring means. A pulse counting means is connected to the output of the frequency multiplying means and the first measuring means, and accumulates the electrical pulses from the frequency multiplying means for a period of time determined by the first measuring means and corresponding to the time required by said application equipment to cover a unit of area. Display means indicates the above accumulated value of pulses which is a measure of the volume of material applied per unit area.
