【 摘 要 】

Coriolis mass flowmeter instrumental and dynamic errors are studied. They can be decreased by the thermocouple usage of R or S types instead of Pt100 sensors. The dynamic error analysis shows that it is able to improve the operation accuracy in the dynamic regime and eliminate the initial period of the flowmeter exploitation in the error compensation absence regime. In consequence of the instrumental error consideration the expediency of the differential thermocouples installation with the reduced performance dispersion, lowered by taking into account of local and extensive inhomogeneities as result of technological deviations of wire production.
