Title:
渦流量計および質量流計に関する出力値を計算する方法
Document Type and Number:
Japanese Patent JP4435309
Kind Code:
B2
Abstract:
A vortex flowmeter senses a pressure of vortices in a flowing fluid and transmits an output related to mass flow. The vortex flowmeter includes a dynamic filter filtering the vortex pressure signal. The dynamic filter provides a first filtered output signal and a second filtered output signal. The dynamic filter includes a controllable transfer function. Control circuitry controls the controllable transfer function and provides an output related to mass flow as a function of the first filtered output signal and the second filtered output signal. Transmitter circuitry receives the output signal and transmits a signal related to mass flow.
