Abstract
A magnetic-inductive flowmeter and a method for operating the flowmeter are disclosed. The flowmeter has a measuring tube, a magnetic field generator, and a controller with first and second measuring terminals. A medium is made to flow through the measuring tube. The controller performs the following steps: generating and feeding an emission signal and receiving a receive signal caused by the emission signal at the first measuring terminal and second measuring terminal; determining an impedance with an impedance amount and an impedance phase using the emission signal and the receive signal; and signaling a short circuit if the impedance amount is smaller than a first limit impedance amount and the impedance phase is larger than a limit impedance phase.
