• The advantage of flanged separators (also called "open flanges") is the large dimension of the diaphragm, which is a prerequisite, for example, for accurately measuring lower pressures or for accurately measuring the pressure in the higher temperature range.
  • Flange dimensions are according to ČSN 131160 resp. DIN 2501: DN25, 32, 40, 50, 65, 80, 100 (mm),  possibly in inches according to ANSI 16,5.
