Flow Meter Barrow SLFV2-RGB W ARGB white - liquid cooling flow sensor for PC loops

Barrow SLFV2-RGB W is a white ARGB flow meter designed for PC liquid cooling loops. It provides continuous monitoring of coolant flow rate inside a custom water-cooling circuit while adding addressable RGB illumination. The device integrates inline with standard tubing or hardline fittings and is intended to help identify reduced flow, air pockets, or pump failure in PC cooling systems without altering loop layout.

Advantages

The flow meter combines accurate flow sensing with addressable RGB lighting in a compact white housing, enabling both functional monitoring and visual customization of a cooling loop. Its design minimises flow restriction while supporting common PC coolant temperatures and pressures. The ARGB lighting is compatible with typical motherboard and controller headers for synchronized lighting effects. Installation does not require additional electronics beyond a standard ARGB connector for illumination.

Suitable for

• Custom PC liquid cooling loops using soft tubing or hardline fittings
• Monitoring pump performance and detecting reduced flow or air in the loop
• Builds that require integrated ARGB lighting for aesthetics and status indication

Key specifications

• Colour: white housing with addressable RGB illumination
• Function: inline liquid flow sensing for PC coolant loops
• Compatibility: designed for standard PC water-cooling fittings and tubing layouts
• Mounting: inline installation within the coolant loop using standard connectors
• Electrical: ARGB illumination requiring a compatible 3-pin addressable RGB header or controller

How to use

Place the Barrow SLFV2-RGB W inline in the cooling loop where visual access and flow monitoring are desired. Secure it with appropriate fittings or tubing clamps according to your loop configuration, ensuring leak-free connections. Connect the ARGB cable to a compatible 3-pin addressable RGB header or controller to enable lighting. After installation, prime and run the loop while checking for steady flow through the sensor; abnormal or fluctuating readings indicate air in the loop, a weak pump, or partial blockage that should be addressed.

Recommendations

Use the flow meter in combination with regular leak checks and coolant maintenance. Place the sensor where air accumulation is less likely to interfere with readings, and ensure the ARGB connection is compatible with your controller to avoid electrical mismatches. Periodically inspect the sensor and fittings for deposits or wear and flush the loop as part of routine maintenance.
