Abstract
Spray systems and control systems for use with spray systems are provided. A method of detecting fluid flow through a nozzle coupled in fluid communication with a solenoid valve including a solenoid coil and a poppet is provided. The method generally includes (1) dispensing fluid through the solenoid valve and the nozzle, (2) de-energizing the solenoid coil to close the solenoid valve and control a fluid flow through the nozzle, (3) determining a closing time of the solenoid valve based on a signal from a poppet measuring device, and (4) determining a fluid flow value based on a time delay between the de-energizing the solenoid coil and the closing time.
