Smartflow's High Temperature Low Flow Indicator lets users visually confirm that cooling media is flowing in a high-pressure hot water mold cooling system by simply looking to see that the impeller is spinning freely.
Flow indicator Burger & Brown’s Smartflow High Temperature Low Flow Indicator has a stainless-steel body that attaches to a mold cooling system with 3/8-inch national pipe thread taper (NPT) or 3/8-inch British standard pipe parallel (BSPP) threaded connections. The indicator works with high-pressure hot water systems, and its body has a high-temperature-glass window that gives users a view of its impeller, which spins to indicate that the cooling media is flowing. It operates with flow rates ranging from 0.08 gallon to 1 gallon per minute and can handle temperatures up to 400 degrees Fahrenheit and pressures up to 250 psi.
What’s new? The High Temperature Low Flow Indicator, which can operate at a much lower flow rate than existing high-temperature flow meters.
Benefits Simple, reliable evidence of cooling media flow. Scale buildup is a constant threat inside restricted high-temperature cooling channels, such as those with bubblers or baffles. If cooling channels become blocked by scale, the rotor will stop moving, providing a visual indication of loss of media movement.
