摘要：A single tube Coriolis flowmeter having a balance bar that enhances theflowmeter sensitivity to material flow. The balance bar's design lowers its secondbending mode response to have a frequency that may be lower than the flow tuberesonant drive frequency. The lowering of the second bending mode frequency of thebalance bar enables the Coriolis response of the vibrating flow tube with material flow toextend force from the flow tube through a brace bar to the balance bar. These Coriolisforces induce Coriolis-like response vibrations in the balance bar because of the loweredsecond bending mode frequency of the balance bar. The Coriolis response of theflowmeter is enhanced since the Coriolis-like response of the balance bar is out of phasewith and is additive to the Coriolis deflection of the flow tube.
