Neptune Systems 1/2" Flow Sensor FS50

Overview

The Neptune Systems FS-50 Flow Sensor provides precise flow monitoring for smaller aquarium plumbing lines. Typically used with return pumps or auxiliary equipment like reactors, this inline sensor connects to the FMM (Fluid Monitoring Module) and delivers real-time flow data directly to your Apex system. With a monitoring range of 30–250 GPH, the FS-50 is ideal for smaller flow applications where accuracy and reliability matter most.

Key Features

• Accurate Flow Monitoring – Measures flow rates from 30–250 GPH.

• Inline Installation – Installs easily into standard 1/2" PVC plumbing.

• Apex Integration – Works with the FMM module to report live flow data to Apex Fusion.

• Durable Construction – Built to withstand long-term use in both freshwater and saltwater systems.

• Custom Fittings Included – Comes with two BSPP x 1/2" slip unions for seamless PVC integration.
