If the batteries in your Flume 2 Water Sensor (the grey device on your meter) are low, we will notify you via email. Your Flume 2 water sensor uses a Flume 2 battery pack, and it can be purchased here.

DO NOT use non-approved Flume 2 battery packs in a Flume 2 device, doing so will void any guarantee of performance and or warranty on the device.

Bring your water sensor Inside before opening it, do not open your Flume Sensor outside at the meter pit.

Here is a quick video that will walk you through the battery replacement process:

To replace your batteries, please follow these steps:

  1. Take a picture of the water sensor device on your meter. Note how it is situated on the meter. You are going to take it off and put it back, so we want to make sure that you put it back in the same spot it is in now. The picture will help you remember exactly where it was.

  2. Take the device off of the meter and bring it inside, find a clean, dry spot to complete the install. Do not open your Flume sensor outside.

  3. Clean and dry the outside of the sensor before opening it to prevent any debris from falling inside. If dirt gets on the seal and the sensor does not close properly there is a high chance moisture will get into the sensor resulting in damage to your Flume.

  4. Carefully open the water sensor lid by using the latch on the top of the sensor and remove the battery pack. When opening the device ensure that no dirt falls inside the sensor.

  5. Insert the new battery pack(s), matching (+) and (-) accordingly. The light in the bottom left should blink yellow twice then green once.

  6. Close the water sensor lid and be sure the latch clicks closed. If the latch doesn't click closed, the water sensor may be susceptible to internal damage.

  7. Put the device back on the meter in the same position it was originally in. You can consult your picture from step 1.

  8. Once your sensor is back on your meter, please recalibrate your Flume by going to the Flume app > Menu (3 lines in the upper left) > settings > Other Troubleshooting > Recalibrate Water Sensor. When the warning message pops up, please press continue and follow the instructions.

  9. It may take your Flume app up to an hour to update the battery signal.
