摘要: A magnetic flowmeter has a tube for supporting fluid flow including circuit indicating when the is empty to prevent an erroneous signal from being provided by flowmeter, as well diagnostic electrodes in are partially fouled. The circuits include amplifier connected two and variable resistor. In normally operating mode, produces oscillating empty,
