Abstract

The control circuits for the electronic flow meter which are the subject of this invention and whose purpose is to meter with precision the flow through a pipe, eliminating disturbances caused by the metering procedure use, consist of an excitation block (2) of coils (B1 and B2) for the magnetic circuit and a processing block (3) for the metering signal which is captured through sensors (S) arranged orthogonally to the magnetic circuit pole components.
