{"title":"A New Approach to Signal Processing for DC-Electromagnetic Flowmeters","authors":"Michael Schukat","volume":2,"journal":"International Journal of Electronics and Communication Engineering","pagesStart":349,"pagesEnd":353,"ISSN":"1307-6892","URL":"https:\/\/publications.waset.org\/pdf\/10708","abstract":"<p>Electromagnetic flowmeters with DC excitation are used for a wide range of fluid measurement tasks, but are rarely found in dosing applications with short measurement cycles due to the achievable accuracy. This paper will identify a number of factors that influence the accuracy of this sensor type when used for short-term measurements. Based on these results a new signal-processing algorithm will be described that overcomes the identified problems to some extend. This new method allows principally a higher accuracy of electromagnetic flowmeters with DC excitation than traditional methods.<\/p>\r\n","references":"<p>[1] Bonfig, K.W. (1970).
