The extremely robust body is made of corrosion-resistant stainless steel<\/strong> (e.g., 1.4571 \/ 316Ti), ensuring reliability even under continuous high-pressure and high-temperature loads.
\n
Optionally, versions in special alloys<\/strong> such as nickel-based alloys or Hastelloy\u00ae<\/strong> are available, suitable for highly aggressive<\/strong> process environments or with high thermal stress<\/strong>.<\/p>\n

Inspection window<\/h5>\n

The Type 520 High-Pressure Flow Sight Glass features two opposing windows<\/strong> made of thermally pre-stressed borosilicate glass<\/strong>, manufactured in accordance with DIN 7080.<\/strong><\/p>\n

    \n
  • They allow for a clear and safe view of the process from both sides.<\/li>\n
  • They also enable targeted illumination of the fluid<\/strong>, ensuring real-time visual monitoring<\/strong> \u2013 a key factor in safety and efficiency<\/strong> in modern processes.<\/li>\n<\/ul>\n
    Flanged connections<\/h5>\n

    The flanged connections comply with DIN EN 1092-1 Form B2<\/strong>, ensuring standardised and secure integration into existing piping systems. Depending on requirements, the flow indicator can be manufactured for pressure classes up to PN 400<\/strong>, making it ideal for high-pressure<\/strong> processes in the following sectors: <\/p>\n
