The tank connection consists of tank seal, a welded flange (EN, ANSI, Fisher
or Masoneilan) or NPT or BSP/G threads (1 or 1.5 in. depending on probe
type, see "Ordering Information".).
Flange dimensions follows standard ANSI B 16.5 and EN 1092-1 type 05
(DIN 2527 type B) blind flanges if the transmitter is ordered with a flange.

Flange connection rating
Flange strength calculations are made with the following conditions:
Bolting material
Stainless steel SA193 Soft (1a) with min.
B8M C1.2 thickness 1.6 mm.
EN 1515-1/-2 group Soft (EN 1514-1) with
13E0, A4-70. min. thickness 1.6 mm.
Calculations show that the following rating applies:
ANSI: according to ANSI B16.5 Table 2-2.3,
max. 302 °F/580 psig (150 °C/40 Bar).
EN: according to EN 1092-1 Table 18, material group 13E0,
max. 302 °F/580 psig (150 °C/40 Bar).
Rosemount 3300 Series
Final rating depends on flange
and o-ring selection.
