Technique for substantially eliminating temperature induced measurement errors from a coriolis meter

Circuitry for measuring first and second input signals comprising:

• first, second and third input channels, having first, second and third channel inputs, for respectively producing first, second and third channel output signals in response to a predetermined characteristic of said first, second and third channel inputs;
• measurement means comprising:
• means, responsive to said first, second and third channel output signals for determining first and second internal offset values respectively associated with first and second pairs of said input channels and for respectively measuring first and second signal values through said first and second pairs so as to produce first and second measured signal values;
• and
• means, responsive to said first and second measured signal values and said first and second internal offset values, for respectively compensating said first and second measured signal values by said first and second internal offset values to yield first and second compensated values, respectively, as measurements of said first and second input signals;
• means for selectively routing said first or second input signals to corresponding inputs of said first, second and third input channels;
• and
• control means, connected to said selectively routing means and to said measurement means, for specifying which one of said input signals is to be simultaneously applied as input to each one of the input channels and for operating said selectively routing means and said first and second pairs of the input channels in conjunction with said measurement means such that while the first pair is determining the first internal offset delay value the second pair is measuring the second signal value and for reversing operation of said channel pairs after a pre-defined interval of time has elapsed such that the first pair will measure the signal value while the second pair will determine the second internal offset delay value so as to continuously measure the first and second input signals and compensate measurements of the first and second input signals produced by each of the channel pairs by the value of the internal offset associated with that particular channel pair.
