Flow Sensors

Flow sensors are used to measure the amount of water flowing through an irrigation system in Gallons Per Minute(GPM). In a typical situation, the flow sensor will transmit the information to a flow meter. Flow sensors are being used more and more throughout the industry to automate some of the common problems dealt with in irrigation systems.

When the flow sensor receives information of too little or to much flow through a certain part of the sprinkler system, it can send an alert to the user (by email, text message or other various means) that there is a problem with the system. The problem could be that a valve is down, a sprinkler is broken or numerous other reasons for too low/high of a flow.

Sprinkler Warehouse carries flow sensors from top brands such as CST (Creative Sensor Technology), Hunter and Toro. As always, we have the largest selection at the lowest prices!
