Еfarm bust control unit. Rare fertilizer application control system efarm bust

Control unit efarm bust. Liquid fertilizer application control system

Description of the product and its purpose
1. Description of the efarm bust system.
The "Bast" system is designed to control the application of liquid fertilizers of all types and subsequent analysis of its effectiveness. System management is performed with an Android device operating system version 5.0 and above.
The following information will be available to the user:

• Actual discharge l/ha
• Actual flow l/min
• Pressure in the system (if a pressure sensor is installed)
• Remaining liquid in the tank
• Speed
• Statistics with the possibility of choosing sorting conditions
• Traveled path (on a specific field)
• Cultivated area (on a specific field)
• Agronomist menu
• Operator's menu
• The rate is controlled by a proportional electric valve.
• Liquid flow is controlled by sectional electric valves (two-way and three-way).

Additional sensitive elements of the system are an inductive speed sensor, a pulse flow meter and a pressure sensor.
