Abstract
A method for operating an ultrasonic flowmeter includes the steps of: emitting a measuring signal having a first part that propagates as an interference signal along and/or within a wall of a measuring tube, and a second part that propagates as a useful signal through a medium flowing through the measuring tube; receiving the interference signal and the useful signal; determining an interference amplitude of the interference signal and determining a useful amplitude of the useful signal; determining an amplitude ratio of the useful amplitude and the interference amplitude; and providing a message if the amplitude ratio falls below a specified lower limit value or exceeds a specified upper limit value. A related ultrasonic flowmeter is also disclosed.
