Product Description
Neptune Flow Sensor - 1/4 Inch
Neptune Flow Sensor - 1/4 Inch is a compact inline flow sensor for measuring low-flow water movement through 1/4 inch tubing when connected to a Neptune FMM module and compatible Apex system.
Low-Flow Monitoring for 1/4 Inch Tubing
This small flow sensor is useful for aquarium applications where flow is too low for larger return-pump sensors. It can be installed inline on 1/4 inch tubing and used to monitor flow through RODI feeds, calcium reactor feed lines, dosing-style water lines, or other low-flow aquarium accessory plumbing.

- Push-fit connectors make tubing connection simple
- Useful for RODI inputs, calcium reactor feed lines, and other low-flow applications

Compatibility and Use Notes
This sensor requires a Neptune FMM module and compatible Apex system to report flow data. Match the sensor to the expected flow range of the line being monitored. Using a flow sensor outside its intended range can lead to poor or unreliable readings.
Setup Directions
Cut the 1/4 inch tubing at the desired monitoring point, insert the flow sensor using the push-fit connections, confirm the correct flow direction, and connect the sensor cable to an available FMM port. Configure the sensor in Apex Fusion, check for leaks, and verify readings under normal operating flow before setting alerts.
