FLM-3 Water Filter Flow Meter with Alarm

Track water passing through a compatible filter installation with an inline flow meter that shows both total volume and current rate.

✅ Follow cumulative filter use - A total-volume reading provides a reference for monitoring water passing through the meter.

✅ Check the flow while water runs - The rate display helps compare delivery under the current installation conditions.

✅ Set a reminder around the reading - An adjustable flow alarm provides an audible prompt for the configured value.

✅ Keep measurement active with a quieter display routine - The power-saving display mode leaves the measurement function operating as described.

Use flow information in the filter-care routine

Water volume and flow rate answer different questions. Total use can support the maintenance schedule, while the current rate helps you observe changes in the connected installation.

The FLM-3 uses standard 1/4-inch connections and a stated 0.8-8 L/min flow range. Match the fittings and operating conditions before installation, and follow the filter manufacturer's replacement guidance rather than using volume alone to determine water quality.
