- Abstract:
- According to digitalization trend in measurement technology, we approached to design the Coriolis meter using digital signal processing (DSP). This paper presents the results of DSP-based control of the meter resonance frequency, which is the condition for its regular operation. Procedure of data manipulation for precision digital harmonic synthesizer and phase-locked loop controller, which run in software on DSP, is presented. Digital control and measurement show advantages in flexibility, repeatability and stability of operation. Developed system for resonance frequency control shows response quickness in order of second and stability in order of 1 ppm.
