Abstract
The present invention provides an improved valve assembly and valve controller for controlling the movement of fluid for irrigation. In according with a preferred embodiment, the present invention teaches a system and method for monitoring the status of a valve assembly and for providing “proof of placement” for selected applicants. According to further preferred embodiments, the present invention includes a valve assembly including a valve controller for applying an electric current to a latch valve thereby switching the latch valve from a first flow state to a second flow state. According to a further preferred embodiment, the valve assembly of the present invention preferably further includes a state/current detector which preferably measures the active current being applied to the latch valve and outputs the measured waveform for analysis.
