Many automatic irrigation systems have pumping systems that are automatically controlled by pressure switches or irrigation controllers. If an irrigation main breaks during an irrigation cycle it can cause damage to the grounds or playing fields. Badger Meter has developed models IR220B and 1500-010 digital flow monitor with programmable relays. The 1500-010 can be used to operate a butterfly valve and shut down a section of the system if the flow exceeds a pre-set limit, indicating a break.
The model IR220B sensors can be mounted on any type of class of irrigation pipe by using a service saddle with a 2"NPT outlet. The 1500-010 can be mounted up to 610m from the sensor. Programming is accomplished via the menu-driven software of the 1500-010.
