digital slurry special use electromagnetic flowmeter

The Electromagnetic Flowmeter for slurry is a kind of electromagnetic flowmeter specialized in measuring pulp, mud, coal water slurry and other slurry media.

Electromagnetic flowmeter for Slurry adopts high and low frequency mixing excitation technology and unique slurry noise suppression and removal technology, effectively improving the ability to measure slurry, with good stability, fast response, it can accurately measure slurry flow concentration up to 78% (solid content).

The key to seriflux measurement is to effectively overcome the influence of multiple seriflux  noises (at least five different noise characteristics), suppress and remove noise, and recover the real flow signal from the complex noise environment.

Based on the theoretical research and in-depth analysis of a large number of experimental data, we adopted high and low frequency mixing excitation technology, modeled the basic seriflux flow signal based on a large number of experimental data, and constructed the signal processing method according to the model based on multiple digital filtering, wavelet transform and dynamic approximation, and made synthetically processing and fast approximation to various seriflux noises.

The adaptive seriflux flow signal model was reconstructed by synthetically processing and fast approximation to various seriflux noises, and finally realized the reappearance the real flow signal.
