More Information


Typical mould tools used in injection moulding reach turbulent flow conditions around 3-4 lpm in 8mm cooling channels. 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 Litres per Minute.

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

  • They measure 0.3 to 4 lpm (0.08 to 1 GPM) for critical cooling circuits
  • Max. Temperature 99°C. Max. Pressure 6.9bar
  • The Design based on our most popular IceCube™ flow meter
  • They are designed to fit our manifolds on ports spacing of 3/8” threads and over
  • They can be mounted to our Delta-Q precision control valves
  • They work with simple ball valve set-up
  • They can be fitted in-line with existing hoses
  • Available with optional temperature and pressure gauges.

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 functionality and suitability to process requirements.
