Pressure - temperature ratings
Pressure - temperature ratings are determined by process connection material and applicable
standards. The tables below detail the allowed maximum process pressure for sensor variants
with stainless steel and Hastelloy measuring tubes.
With two major exceptions, the pressure rating of the flow sensors is independent of the process
medium temperature. Design rules for flange connections in both the EN1092-1 and ASME
B16.5 standards dictate pressure derating with increasing temperature. The charts below show
the effect of process medium temperature on the pressure ratings for the flanges within the
product program.
