Irrigation flow converter, monitoring system and intelligent water management system
First Claim
1. An intelligent water management system, comprising:
- a water meter reader converter for converting a water use quantity information from a water meter to electrical signals and for transmitting the electrical signals, wherein the water use quantity information from the water meter comprises irrigation water use quantity information corresponding to water flowing across the water meter to an irrigation water connection, and a non-irrigation water use quantity information corresponding to water flowing across the water meter and to a non-irrigation water connection;
a plurality of electrically controlled irrigation valves for receiving an electrical valve actuation signal and for controlling irrigation water to a plurality of irrigation water emitters based on the receipt of said electrical valve actuation signal, each of the plurality of electrically controller irrigation valves being hydraulically coupled between the irrigation water connection and a respective plurality of irrigation water emitters;
an intelligent irrigation controller for receiving the electrical signals from the water meter reader converter and for distinguishing, from the water use quantity information derived from the electrical signals, one of the irrigation water use quantity to the irrigation water connection and the non-irrigation water use quantity in the non-irrigation water connection and for generating said electrical valve actuation signal.

Abstract
The present invention is directed to an intelligent water management irrigation system for monitoring the total water usage for a billing site and preventing cumulative water usage from exceeding a water budget by adjusting the amount of water used for irrigation. Irrigation zone priority values are selected for each irrigation zone that specify a percentage of the full water need that the foliage in the zone can survive and are saved in an intelligent water management irrigation (IWMI) controller. The IWMI controller receives water usage information originating from a property'"'"'s water meter and compares the measured water usage with the allowable water budget. Water usage is tracked separately for the household use and landscape use (irrigation). Prior to each irrigation cycle, the IWMI controller estimates the amount of water that will be needed by the landscape and for household use during the remainder of a billing cycle; household use is given precedence over landscape use. If the water budget will support both, irrigation can proceed normally. If the budget will not support both, the IWMI controller estimates the amount of water needed for the remainder of the billing cycle if only a priority watering amount is allocated for each landscape zone. If the water budget will support priority irrigation, landscape watering can proceed in priority irrigation mode. If the water budget will not support priority irrigation watering, the irrigation cycle is skipped and the water usage estimations are recalculated prior to the next irrigation cycle.
