Flow indicator for water loops

The Alphacool Eisflügel G1/4 flow meter lets you confirm coolant movement at a glance. A six-blade plexiglass rotor spins inside a black acetal housing, and the dual-colour yellow and blue vanes stay readable whatever dye you run. It threads into any standard G1/4 port and adds a visible safety check for custom loops.

Extra top port for fill or drain

A third G1/4 thread on the top face accepts a plug, an LED, a fill port, a drain valve or an angled fitting without blocking flow. The supplier includes one screw plug in the box so the port is sealed out of the box. This flexibility means you can add lighting or maintenance access without buying a separate T-block.

Simple inline install, watch orientation

Push the meter between two G1/4 fittings and tighten by hand; no tools or software are required. The only common mistake is fitting it backwards — flow must match the arrow on the body or the rotor will not spin. Acetal and plexiglass tolerate standard coolants, but avoid aggressive solvents that could cloud the window.

Questions about this item

Does the internal impeller in the 17350 need periodic cleaning or replacement?

The six-blade impeller is moulded from plexiglass and has no service interval; if debris builds up you simply flush the loop during normal coolant changes.

What is the first limitation you hit when running this flow meter continuously?

The acetal body and G1/4 threads set the pressure and temperature ceiling, so the loop’s coolant limits are reached before the meter itself becomes a restriction.

How much extra pump noise or heat does the Eisflügel add when the system runs all day?

It adds no noise — there is no motor — and the impeller spins passively, contributing negligible heat to the coolant.
