SMARTFLOW® Low Flow Indicators

Smartflow® Low Flow Indicator is an in-line device using a high-visibility impeller to show water movement inside a cooling line with flow between 0.3 and 4 Liters per Minute.

Low Flow Indicators are ideal for use in critical injection mold cooling circuits using bubblers or baffles where flow is restricted and effective cooling is essential.
