## Summary description

The Alphacool 17558 flow indicator is designed to monitor fluid flow in computer cooling systems. Made from durable Acetal material, it features a sleek black design. With dimensions of 58mm width, 25mm depth, and 25mm height, it is compact and easy to install. This product is essential for ensuring optimal cooling performance in your system.

## Long description

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.
Usage 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.
