Hunter HC flow meters measure water flow through the mains when an irrigation zone is active.
The flow meter can also detect faulty valves or pipes. The flow meter also allows you to understand the amount of water being placed on your garden. A flow meter means that you can monitor your irrigation system remotely without need to visit onsite.
Important: For accuracy of recorded flow meter data it is suggested for best practice to have the flow meter connected to the main line that connects to the irrigation system and not the main line of the entire water supply as this can cause confusion when reading flow data.
For example if your flow meter is connected to the main line of you entire water supply even when you open a tap, flush the toilet or have a shower. The flow data will be recorded under your flow measurements, however will appear as flow data ”while a zone was not active“ so please keep this in mind when installing your flow meter off your main water supply which isn't exclusive to your irrigation system.

Are there any safety standards my irrigation system must meet?
The main safety concern is regarding the water supply. To avoid contamination of the mains water upstream, in most municipalities, a Dual Check Valve is required at the water connection.
Can I get away with placing my indoor controller outside?
In rare applications, like on a wall under a well covered patio where the space is 100% dry all the time & not exposed to the sun, an indoor controller will continue to operate without issue. But if you’re not sure, we recommend installing an outdoor model. If something does go wrong with your controller due to water damage or the LCD screen failing from sun exposure, the warranty is voided so it’s not worth the risk.
Can I run an irrigation system off a regular garden tap?
A garden tap is an excellent place to connect your irrigation system. Ideally, install a connection point behind the tap (turn the water off first) so you can still use your tap to fill a bucket when you need to.
Can I run my system manually from the controller?
Yes, irrigation controllers typically have a manual function, this will allow you to both operate all zones, or each one individually as you please.
Do I need a plumber to install or fix my system?
No, unless you’re tapping into your water supply, a plumber isn’t required. Most domestic irrigation systems can be installed by anyone half handy.
Do I need a rain sensor?
In some states a rain sensor is mandatory, but regardless it’s something you should include in your irrigation system. Having your system turn on in the middle of a day of rain is not only embarrassing, it’s a terrible waste of water & the overwatering is bad for your garden!

Will an irrigation controller operate all zones at once, or one at a time?
Domestic irrigation controllers will always operate zones one at a time. Even if you try to operate 2 to come on at the same time, the controller will automatically delay the operation of the second zone until after the first zone has finished running.
