Abstract
Systems and methods can determine a liquid flow in a spraying system. An amount of liquid that is output from the spraying system during a pump cycle is determined. A number of pump cycles that occur within a given amount of time are measured. The number of pump cycles are measured using an electronic speed controller (ESC). Additionally, the ESC indicates the number of pump cycles within a given amount of time within a threshold of precision. The amount of liquid flow in the spraying system is calculated based on the measured number of pump cycles and the determined amount of liquid that is output from the spraying system.
