Title:
【発明の名称】コリオリ流量計に使用されるピックオフと振動型駆動装置との組合わせ、及びこの組合わせを使用する方法
Document Type and Number:
Japanese Patent JP3469550
Kind Code:
B2
Abstract:
An oscillatory vibration driver is operably connected to a Coriolis flowmeter for use in vibrating the meter flow tubes. The meter electronics contain a mimetic circuit that permits use of the driver as a signal pickoff which provides a measurement of back electromotive force for use in calculating mass flow rate and density from the Coriolis flowmeter. The mimetic circuit contains an analog coil and magnet that facilitate the measurement of back electromotive force, or the mimetic circuit may comprise digital means.
