Monitoring your water flow meter for your irrigation or operational indoor systems is important for leak detection, abnormal use, or billing verification.

Keeping the landscaping and flowers in front of the office looking their best is very important for property appearance and customer happiness.

Having a wireless flow monitoring system helps maintain appearances. A wireless monitoring system simplifies installation and provides easy scalability and expansion for any irrigation, indoor, and industrial water system.

Essential Features for Smart Irrigation

Here are a few important features to consider when choosing a smart irrigation system and monitoring system:

Flow Rate & Total Water Use Tracking:

You want to select a monitoring system that can show you the real-time flow rate as well as the total water usage for any given date or zone.

This tracking data will allow you to compare water usage over many months or years by viewing graphs of the water flow on any given date.

All of this water flow data is logged so you can even compare last year’s water usage versus this year’s.

Leak Detection & Alerts:

Since the water meters listed in this article all have digital outputs they can be connected to a small wireless device that can report the meter’s flow state in real-time.

This allows you to monitor even the slightest water flow usage.

This provides you with several advantages including:

  • Leak Alerts
  • Unscheduled Usage Alerts
  • Utility Billing Comparison

Leak alerts are critical since they can quickly send a message to your property manager about leaks so they can address the problem and limit the high utility bills and flooding liabilities.

See more information on commercial leak detection systems.

Unscheduled usage alerts will let you know if the irrigation or indoor water is being used when it should not be. This provides the date and time the water was being used so it can be linked to any personnel at the property during that time.

Utility bill comparison will allow you to compare your monthly utility bill to see if there are any gross errors that need to be addressed.

Zone-Level Monitoring:

You should be able to monitor each zone independently as well as set schedules. In addition, the monitoring system should tell you if a zone or valve is malfunctioning so it can be repaired.

Zone-level monitoring is easy with a point-to-point system but if you have a 2-wire system it may take a bit more time to diagnose a bad valve or zone.

Integration with Smart Controllers:

Your irrigation system should have the necessary interfaces that can connect to any smart controller, such as master valves, pulse wiring, and zone valve controls.

A good smart controller will also have a cellular or wifi interface that connects the irrigation system to the real-time monitoring service so alerts and be issued as needed.

Remotely Monitoring Flow of your Irrigation Systems:

You should be able to monitor and control your entire system from a desktop web browser or a mobile phone app.

This allows maintenance personnel to easily test zones from their phone and troubleshoot valves if there is a problem.

Top Wireless Water Flow Monitoring Options

Some of the popular brands of smart irrigation controllers are:

  • Banyan Water
  • Hunter
  • Rain Bird

If you have any existing Hunter or Rain Bird, for example, a Banyan Water controller can be connected to these existing systems to provide a fully monitored wireless system.

Keep in mind, that these controllers must connect to existing zone valves or flow meters.

How do Flow Meters Work

Flow meters work by using a mechanism inside a water meter or valve that turns a wheel as water passes through the pipe.

There are other ways to measure water flow through pipes.

Here are the different types of flow meters:

  • Pulse or Reed Switch
  • Ultrasonic

Pulse or Reed switch type flow meters have a wheel or magnetic rotor that turns as water flows through it. This is a moving part since it must spin as water is flowing.

An ultrasonic flow meter uses sound that bounces off the inside of the pipe to measure water flow. This type of flow measure uses no moving parts and can be attached to an existing pipe easily.

Choose the Right Flow Meter for your Needs

Flow rate involves sizing the correct valve size and specifications that will work properly at your maximum water flow usage.

Temperature and location of the valve is also a consideration.

So, the flow meters measure the actual water flow usage and the smart irrigation controllers report this flow data to the monitoring service.

The following are examples of the best water flow meters that are used for irrigation and indoor systems. These water meters each have wiring that connects directly to a wireless smart irrigation system:

Beyond Flow Meters: Additional Smart Irrigation Tools

A good smart irrigation monitoring system will provide many automated features as it relates to your irrigation or indoor systems.

For example, weather monitoring in your area is used to adjust the schedules of your irrigation system so you don’t start the sprinklers after it has rained or, in winter, seasons, the system can be put into a suspended mode if freezing temperatures are expected.
