Smartflow® High Temperature Low Flow Indicators are designed to show the presence of cooling media movement in very low flow applications. This high temperature indicator comprises a high-visibility impeller and robust flow body designed for punishing duty.
High Temperature, Low Flow Indicators are ideal for use in critical injection mold cooling circuits such as bubblers or baffles where flow is restricted and effective cooling is essential.
We recommend using only extremely clean cooling water through the attached channels to reduce the buildup of deposits that adhere quickly in high temperature cooling circuits. Scale deposits can coat the inside of cooling water channels, effectively creating barrier insulation preventing efficient heat transfer.
