ELECTROMAGNETIC FLOW METER |
摘要 |
A magnetic flow transmitter provides a coil driver output at a selected fundamental to a coil on a flow tube carrying a flow of a liquid. An amplifier amplifies an electrode signal from the flow tube and an A/D converter converts the amplified electrode signal. A digital signal processor (DSP) uses a spectral transform such as a Fourier type transform to generate a flow output based on spectral components at or near the fundamental and a noise diagnosing output based on components at or near a noise frequency. |
