Abstract
A method of detecting fluid flow through a solenoid valve in a fluid application system includes dispensing fluid through the solenoid valve, de-energizing a solenoid coil of the solenoid valve to close the solenoid valve and control a fluid flow through the solenoid valve, determining a closing time of the solenoid valve based on a signal from a poppet measuring sensor, determining a time delay between the de-energizing the solenoid coil and the closing time, and determining a fluid flow value based on the time delay.
