Small rectangular digital flow meter with OLED screen showing flow temperature and speed

BFKK

BFKK Digital Flow Meter Temperature Display

SKU CH-Q81E-2NYAF

Monitors coolant flow and temperature in real time with a clear OLED display and pump-failure alarm

  • Real-time flow and temperature monitoring for instant system insight
  • High-definition OLED screen shows flow, temperature and rotation speed clearly
  • Three operating modes give clear performance overview at a glance
  • Pump-stop alarm alerts immediately when water circulation fails
  • Accurate to one decimal point for precise liquid-flow tracking

Integrated Flow & Temperature Monitor

The BFKK Digital Flow Meter Temperature Display combines a flow meter and thermometer in one unit for water-cooling loops. It provides real-time monitoring of coolant flow rate and temperature so builders can verify system operation at a glance.

Suited for custom-loop builders who want live

This device suits enthusiasts assembling or maintaining custom liquid-cooling systems who need immediate visibility of flow, temperature and pump speed. It is not intended for users of closed-loop coolers that lack accessible fittings or sensor ports.

Continuous visibility under load

The high-definition OLED screen shows flow, temperature and rotation speed simultaneously during extended operation. If the pump stops or flow drops, an alarm triggers immediately, giving constant assurance that the cooling loop remains within safe limits.

Questions about this item

What type of fittings does the flow meter need to connect to my existing water-cooling loop?

The meter installs inline in a standard liquid-cooling loop, so you will need compatible tubing and fittings that match your loop's inner and outer diameters.

Can the flow meter monitor the speed of a pump I already own?

Yes, the OLED shows rotation speed alongside flow and temperature, letting you verify that your existing pump is running at the expected RPM.

How do I confirm the meter is reading correctly once it is installed?

Power the system and check the OLED for real-time flow, temperature to one decimal place, and pump RPM; an alarm will sound if the pump stops spinning.
