On Titanium tube meters, it is, however, possible to exceed 150°C up to an absolute maximum
of 200°C, for short periods. The time is limited by the initial temperature and final temperature.
To assess the time allowable, refer to figures 11,12 and 13, which cover the 10G+, 100G+ and
300G+ meters. For the 800G+ and 1500G+ refer to Krohne Ltd.
This does not apply to the 3000G+. These meters must not exceed 130°C. Zirconium tube
meters must never exceed 100°C.
