Indicateur de débit Alphacool 17558 Acétal noir 58 mm

The Alphacool ES "HighFlow" with tacho signal is a compact combination sensor for monitoring water temperature and flow in PC liquid cooling loops. It installs directly into a loop using two G1/4" internal threads and is compatible with both soft tubing and HardTubes. The unit uses a durable Acetal body and is intended to provide continuous flow measurement alongside temperature monitoring for system diagnostics and control.

Advantages

The sensor combines an NTC 10 kΩ temperature probe and an internal flow meter in a small enclosure with two G1/4" internal threads for easy integration. The temperature probe covers a wide range (-40 to 125°C) and terminates in a 2-pin connector compatible with many motherboards and external controllers. A tacho-style flow signal and a 42 cm flow sensor cable are provided to enable continuous flow monitoring. The compact 58 mm-wide Acetal housing makes the unit suitable for tight installations in PC cooling loops.

Suitable for

• Monitoring coolant flow in PC liquid cooling systems
• Measuring coolant temperature in water-cooling loops
• Integration with motherboards or external controllers that accept NTC sensors
• Installations using soft tubing or HardTubes with G1/4" connections

How to use

Screw the appropriate G1/4" fittings or adapters to the sensor, then install it at any convenient point in the cooling loop. Connect the 2-pin temperature cable to a compatible motherboard header or an external controller with an NTC input. Connect the flow sensor cable or tacho output to the monitoring device or controller that accepts flow/tacho signals. Ensure all fittings are tightened to avoid leaks and bleed the loop after installation to remove air pockets.

Recommendations

Check your motherboard or controller manual for compatible NTC and tacho input pins before connecting. Use appropriate G1/4" fittings and verify leak-tight installation. Do not expose the sensor to fluids or conditions outside the specified temperature range.
