LOW THERMAL STRESS BALANCE BAR FOR A CORIOLIS FLOWMETER |
摘要 |
A Coriolis flowmeter that uses a balance bar to allow stress in the active and inactive portions of the flow tube to be as low as possible for any thermal condition. The balance bar has a middle segment that is compliant in the axial direction so that changes in length of the balance bar ends do not impose a significant axial force on the flow lube. This ensures that the thermal stresses on the active and inactive portions of the flow tube are always equal. This state of stress equality is the lowest possible stress state for the flow lube. As a result of the axially compliant balance bar, the remaining stress in the flow tube is only a function of the differential expansion between the flow tube and the case. Balance bar expansion and contraction is eliminated and has no impact on the flow tube stress. |
