Knowing the level of product in a bunker allows you to solve problems of accounting for seeds, fertilizers, and crops. Monitoring the dynamics of level changes, taking into account the speed of movement and the cultivated area, makes it possible to control the seeding rate/fertilizer application during sowing, and the yield during combining. The bulk materials level sensor (hereinafter referred to as the sensor) is specially designed for use with a transport monitoring system - it is a modified fuel level sensor.

For specialized accounting, you can use special agricultural software. | ||
