What is Flume?

The Flume Smart Water Sensor will let you monitor your water usage right from your smartphone. In addition, the Flume System will notify you if you have any leaks (inside or outside).

How does Flume Work?

There are three components of the Flume solution:

  • The Flume Water Sensor

  • The Flume Bridge

  • The Flume App

When water flows through your water meter, a magnetic disc spins inside of the meter. The rate at which this disc spin correlates directly to a water flow rate.

The Flume Water Sensor simply straps onto your meter, and it measures this magnetic field from the meter. It then sends this information using Radio Frequency (RF) to the Flume Bridge. We use RF because it requires very little power (great for battery life) and it can transmit a signal up to about 1000 feet (great for meter pits that are far from a home).

The Flume Bridge plugs into a power outlet inside of your home, and it connects to your WiFi network. It receives the signal from the Flume Water Sensor, and it sends this data securely into the cloud.

The Flume App, which runs on your smartphone, can then access your water usage data from the cloud. Not only can you analyze your water usage data from this app, but you will also be notified of any abnormal usage (such as a leak).

Can I install it myself?

Yes! Most people can install our product in less than 15 minutes. You do not need to cut any pipes, and no plumber is required. The Flume app walks you through the entire installation step-by-step.

The Flume Water Sensor needs to be attached to your water meter, requiring you to lift the lid and reach into the meter pit. If you will need assistance with either of these activities, you may want to ask a friend or family member to help you with your installation.

What if I need help?

Our world-class support team can assist you if you have any problems or questions. We can be reached from 7 AM until 7 PM PT, 7 days a week. Simply click the chat icon from within your Flume app to reach us. Or if you prefer, you can email us at

Are there any special requirements?

Before you order your Flume device, please make sure that you meet both of the requirements below:

  1. Your home must have a wireless network (WiFi). You must also know your WiFi password.

  2. You must have an iOS (Apple) or Android device.

What if Flume notifies me of a leak?

Many of our customers discover leaks within the first few hours of using our device. Even though our device lets you know about a leak, it can't tell you where it is. Here is a guide from SAWS that provides some helpful tips on how to identify the source of your leak.

Who will be able to view my water usage data?

Your water usage data will be shared with SAWS and Flume.
