MAGNETIC FLOW TRANSDUCER AND FLOW METER INCORPORATING THE SAME

摘要

A magnetic transducer (109) for measuring the flow of a fluid (108) has electrodes (102) and an alternating magnetic field (107), an electrode (102) having lower noise energy at frequencies below 5Hz than an electrode comprising carbon or corrosion-resistant metal alloy. The noise characterist ic of the electrode (102) at magnetic field frequencies around 1 Hz is lower th an that of an electrode comprising carbon or corrosion-resistant metal alloy.
