Flow Meter Barrow SLFV2-RGB B — ARGB flow sensor, black

Barrow SLFV2-RGB B is an ARGB-capable flow meter designed for PC liquid cooling loops. Housed in a black enclosure, the unit measures coolant flow rate with an integrated sensor and provides addressable RGB illumination to indicate operational status. It is intended for inline installation in desktop water-cooling systems to help monitor pump performance, detect interruptions or low-flow conditions, and contribute to safer temperature management.

Advantages

The flow meter combines real-time flow monitoring with addressable RGB lighting, allowing both functional feedback and visual status indicators. Its compact form factor and standard fittings simplify integration into existing loops while the black finish offers a neutral look that matches most builds. The sensor delivers continuous flow data for quick detection of reduced or stopped circulation, supporting preventive maintenance and troubleshooting.

Suitable for

• Custom PC water-cooling loops requiring active flow monitoring
• Systems where visual flow status via ARGB lighting is desired
• Environments needing quick detection of pump failure or blockages
• Desktop builds looking for a compact, black inline flow sensor

Key specifications

• Function: inline liquid flow measurement for PC cooling loops
• Lighting: addressable RGB (ARGB) illumination for status indication
• Color: black housing
• Sensor type: integrated flow sensor for continuous monitoring
• Form factor: compact inline module suitable for standard tubing and fittings

How to use

Install the flow meter inline with the coolant path following the manufacturer’s recommended flow direction, ensuring secure connections with compatible fittings or tubing. Connect the ARGB header to a compatible motherboard or controller to enable lighting control. Use your system’s monitoring software or hardware interface to read flow data and set alerts where available. Verify leak-free installation before powering the pump and observe the ARGB indicators to confirm normal operation.

Recommendations

Place the flow meter after the pump or in a straight section of tubing for stable readings; avoid installing directly before restrictive components. Periodically inspect connections and clean the sensor housing when servicing the loop. Ensure ARGB connections match the voltage and pinout of the controlling header to prevent lighting issues.
