Flow velocity
The permitted flow velocity is the minimum defined by the resonance velocity (resonance
distance 80%) and stress or buckling caused by flow, which would lead to failure of the
thermometer tube or to the safety factor (1.9) being exceeded. The calculation was performed
for the specified limit operating conditions of 200 °C (392 °F) and ≤ 100 bar (1
450 psi)
process pressure.
