Abstract
A plugged nozzle monitoring system uses a thermal flow sensor located within a spray nozzle of an agricultural sprayer. The thermal flow sensor is free of moving parts and is made of corrosion-resistant materials. The thermal flow sensor is placed within the fluid flow path through the nozzle and activates an alarm if flow through the nozzle falls below the baseline value.
