Flow Meter for Custom Loops

This water flow meter monitors coolant movement in a custom liquid-cooling circuit. It connects via a standard 5 V three-pin header for power and signal. The black aluminum-alloy body fits cleanly into a themed build. It is aimed at enthusiasts assembling their own open-loop cooling systems.

Power and Signal Constraints

The device draws power from a 5 V three-pin motherboard or controller header, so a compatible header must be available. It reports flow rate through that same connection without a separate sensor cable. No onboard display is included; readings depend on software linked to the header. Builds lacking a spare 5 V three-pin header cannot use the meter.

Upgrade from Guesswork

The meter replaces visual estimation of flow with a measured signal, letting builders confirm pump operation and detect blockages. The jump is worth it when troubleshooting silent pump failure or verifying loop integrity after maintenance. It does not add cooling capacity or replace a temperature sensor. Builders who rely solely on reservoir observation gain no new data.

Questions about this item

Should I choose the LRC2.0 version or another flow meter model?

The LRC2.0 is the only version listed for this FormulaMod water flow meter, so no alternative model is offered here.

What does the 2.0 reading tell me once the meter is installed in my loop?

It shows the real-time coolant flow rate so you can confirm the pump is moving fluid at the expected level.

How does the 5 V 3-pin connection limit what the meter can do?

The 5 V 3-pin header powers the sensor and LEDs but carries no PWM signal, so the meter reports flow without controlling fan or pump speed.
