Abstract

Abstract ABSTRACT OF THE DISCLOSURE 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 corres-ponding 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.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 228 words
A device, for monitoring a unit of volume of liquid or granular material applied per unit area by mobile application equipment having flow measuring means, comprising: first measuring means for attachment to the application equipment for generating electrical pulses which have a frequency that is proportional to the rate at which the unit of area is covered by said application equipment; second measuring means for attachment to the flow measuring means for generating electrical pulses which have a frequency that is pro-portional to the rate at which the unit of volume of material is applied by said application equipment; frequency multiplying means for multiplying the frequency of the electrical pulses from said second measuring means by a calibration factor that is determined by the size of the unit of area and the size of the unit of volume to produce electrical pulses; pulse counting means connected to the frequency multiplying means and the first measuring means for accumulating the electrical pulses from said 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 the unit of area, and display means connected to the pulse counting means for indicat-ing the accumulated value of pulses in said pulse counting means, the accumulated value being proportional to the volume of material applied per unit area.
Claim 2
Independent Claim 228 words
A device, for monitoring a unit of volume of liquid or granular material applied per unit area by mobile application equipment having flow measuring means, comprising: first measuring means for attachment to the application equipment for generating electrical pulses which have a frequency that is proportional to the rate at which the unit of area is covered by said application equipment; second measuring means for attachment to the flow measuring means for generating electrical pulses which have a frequency that is pro-portional to the rate at which the unit of volume of material is applied by said application equipment; frequency multiplying means for multiplying the frequency of the electrical pulses from said second measuring means by a calibration factor that is determined by the size of the unit of area and the size of the unit of volume to produce electrical pulses; pulse counting means connected to the frequency multiplying means and the first measuring means for accumulating the electrical pulses from said 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 the unit of area, and display means connected to the pulse counting means for indicat-ing the accumulated value of pulses in said pulse counting means, the accumulated value being proportional to the volume of material applied per unit area.
Claim 3
Dependent Claim 23 words
A device as set forth in claim 1 wherein the first measuring means is attached to a wheel associated with the application equipment.
Claim 4
Dependent Claim 38 words
A device as set forth in claim 1 wherein said frequency multiplying means has provision for gain adjustment to compensate for changes in the size of the unit of area or the size of the unit of volume.
Claim 5
Dependent Claim 38 words
A device as set forth in claim 1 wherein said pulse counting means accumulates said electrical pulses from said frequency multiplying means for a period of time corresponding to a number of pulses from said first measuring means.
