Modern radiant floor, wall or ceiling heating systems<\/strong> represent one of the most efficient solutions for combining living comfort<\/strong>, energy savings<\/strong> and environmental sustainability<\/strong>. Flow anomalies, accumulation of impurities or deposits can compromise the operation of pumps, valves and boilers<\/strong>, causing costly and potentially dangerous failures. Flow meters<\/strong> installed in radiant systems allow visual verification of hot water flow regularity<\/strong> in the circuits. Meeting these requirements are Multitherm<\/strong> and Duroset Technologie Plastics<\/strong>, which have chosen LASULF compound<\/strong>, a high-performance material based on polysulfone (PSU)<\/strong>, for manufacturing flow meter bodies for their heating systems.<\/p>\n Polysulfone (PSU)<\/strong> is a transparent amorphous thermoplastic<\/strong> that offers an ideal balance between mechanical robustness, thermal resistance and chemical stability<\/strong>. PSU<\/strong>, thanks to its amorphous nature<\/strong>, allows production of components with excellent geometric precision<\/strong> and tight tolerances<\/strong>, reducing the risk of leaks at joints and improving overall system safety.<\/p>\n The use of resistant transparent compound for flow meters<\/strong> such as LASULF based on PSU<\/strong> ensures: <\/p>\n
\nThese systems use low-temperature hot water<\/strong> that circulates within integrated hydraulic circuits<\/strong> that are not visible, making constant monitoring of flow and quality of the heat transfer fluid<\/strong> essential.<\/p>\n
\nFor this reason, water flow visibility<\/strong> is a crucial element for maintenance and safety of the entire system.<\/p>\nTransparent Flow Meters: Function and Technical Requirements<\/h2>\n
\nTo ensure consistent performance over time, the transparent bodies of these components must combine mechanical resistance, dimensional stability and optical integrity<\/strong>.<\/p>\nThe Role of PSU in High-Performance Flow Meters<\/h2>\n
