Title:
ELECTROMAGNETIC FLOW METER WITH SELF-CORRECTION CAPABILITY, INCREASING THE MEASUREMENT ACCURACY, REDUCED STARTUP AND MAGNETIC FIELD PROTECTION
Document Type and Number:
WIPO Patent Application WO/2020/141426
Kind Code:
A1
Abstract:
A method for self-correction of a fluid flow measured by an electromagnetic flow meter is utilized by applying an excitation signal to a coil, where the coil is configured to apply a magnetic field to a fluid that passes through a tube, generating a first signal by a processor, where a first signal frequency is different from an excitation signal frequency, applying the first signal to a first electrode of the electromagnetic flow meter in the intervals between two consecutive excitation signals, detecting a second signal by a second electrode of the electromagnetic flow meter, determining a flow rate factor based on comparing the second signal with a data stored in a storage unit, and updating the fluid flow according to the flow rate factor.
