The Brita water flow meter is a device that allows accurate measurement of the amount of water flowing through Brita filter cartridges.

By installing a flow meter on the filter cartridge system, the user can monitor the amount of water used and in this way decide more easily when the cartridge needs to be replaced. In addition, the flow meter also has a display that shows information about the time the cartridge was used and the amount of water flow during that time.

The flow meter also has a warning display of battery capacity and usage, which is very useful for monitoring the status of the meter. The flow meter is therefore an ideal addition to Brita's filter cartridge system, as it enables the user to accurately monitor water consumption and the time interval between cartridge changes.
