Electromagnetic flowmeters are said to be the best solution in many applications, because they measure the average velocity even when the filling of the channel varies and the local streams fluctuate. Despite the relatively simple principles of operation, the question of which signal processing method can handle flow parameter estimation in a noisy environment is still open. The estimators based on...
The presented paper describes a quantitative assessment of a new concept of signal processing to be applied in the field of electromagnetic flow meters for open channels. The main goal of the concept is to take the advantage of a signal model including simultaneous information about the medium flow rate and height of filling with the use of the least squares method. The wavelet approach to signal...
The paper presents a quantitative assessment of a new method of signal processing to be applied in the field of electromagnetic flow measurement for open channels. The main goal is to use a signal model including simultaneous information about the medium flow rate and height of filling with the use of least squares method. As the methods of noise removal, polynomial approximation and inverse FFT are...
