Fig. 15: Permitted flow velocity
L = insertion length, during flow
v = flow velocity
Medium: ----- air; - - - - - water
The permitted flow velocity is the minimum from resonance velocity (resonance distance 80%)
and load or buckling caused by flow, which would lead to failure of the thermometer tube or to
exceedance of the safety factor (1.9). Calculation was performed for the specified limit operating
conditions of 200°C (392°F) and ≤10 MPa (1450 PSI) process pressure.
