Liquid Fertiliser Regulation Systems TRIZ Cases

Powerline communication lets chemigation controllers use existing irrigation wiring to add chemical injection without excavation or landscape damage.

During turns, computed speed limits keep outer nozzles at the target application rate, improving spray uniformity across the field.

Ground-speed-based PWM frequency control keeps liquid application patterns uniform and avoids gaps or over-application as field speed changes.

Multiple parallel flowmeters with valve switching extend measurable flow range while preserving fast, precise, and reliable readings.

Upstream pressure sensing lets a monitoring system tune PWM valve duty cycle and frequency for uniform spray patterns and lower chemical waste.

Interchangeable travelers and springs let one three-way valve tune flow rates and pressure differentials while magnetic sensing tracks plunger movement.

Real-time soil pH, moisture, and fertilization data feed a neural model to infer nitrogen content and precisely adjust corn fertilizer use.

A movable probe, cam lock, and integrated rinsing head enable spill-resistant chemical transfer and container cleaning in closed systems.
