Flow sensors function like your home’s water meter, but for your sprinkler system. While your water meter measures your entire water usage for your home, your flow sensor measures only your sprinkler’s water usage and the irrigation system’s flow rate.
It is useful knowing how much water it takes to irrigate your lawn. The crucial aspect of a flow meter (which is another name for a flow sensor) is in its measurement of your sprinkler rate of flow. This device measures and establishes a baseline for average rate of water flow, then monitors changes above and below that norm. That means the flow sensor can detect leaks or clogs in the system based on the flow of water.
These devices are wired into the irrigation system controller. This enables accurate on-site flow monitoring and measurement when installed with or retrofitted to any Bio Green sprinkler system. When wired into a Rain Bird smart sprinkler controller, like the one included with Bio Green’s Ultimate Sprinkler system, the flow sensor automatically uploads its data to the (free) Rain Bird irrigation management mobile app.
Paired with a WiFi-enabled, smart device compatible system like this, the flow sensor transforms from a passive alert system to an active leak detection and prevention device. When the flow sensor registers a change in the flow rate, it automatically quarantines and shuts down only the area where it detected unusual flow. Whether the leak is caused by a broken head or damaged piping, the flow sensor only shuts down the affected part of the system while continuing to water other areas as normal.
This device can help save water, money and parts of your lawn that can be negatively impacted by under and over watering due to sprinkler system damage or malfunction. Rather than wait until a scheduled maintenance check to discover the system has been wasting water, a flow meter can detect system issues quickly. And with a water-smart irrigation controller, the flow meter can even prevent additional water loss and system damage.
You may want to consider including this all-important device in your next sprinkler system purchase or upgrade!
