Low Flow Indicators/Regulators

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.

The polysulfone viewing window is compatible with common cooling liquids. Wetted parts are made from corrosion-resistant materials in a proven design platform.

Optional temperature and pressure gauges can be added as needed for increased funtionality and suitability to process requirements.

Delta-Q® Precision Flow Regulators may be added when additional flow control is desirable.
