Method for ascertaining a fill level of a pipe on which are arranged a first and a second drivable measuring electrode (22, 24) and which is provided with at least one earth electrode (30, 32, 34), comprising the steps of: a) providing the pipe in a state at least in part filled with a fluid; characterised in that the method further comprises the steps of: b) exciting the first and second measuring electrodes (22, 24) with contradirectional measuring currents, wherein the measuring currents bring about current flow from the first measuring electrodes to the second measuring electrode, and detecting at least one first measured value at each of the first and/or second measuring electrodes (22, 24); c) exciting the first and second measuring electrodes (22, 24) with equidirectional measuring currents, wherein the measuring currents bring about current flow from the first and second measuring electrodes (22, 24) to a first earth electrode or vice versa, and detecting a second measured value at each of the first and/or second measuring electrodes (22, 24); d) ascertaining the fill level of the pipe on the basis of at least the first and second measured values (26, 28) according to steps b) and c), wherein, in a further step e), a voltage induced in the fluid by a magnetic field is detected by the first and/or second measuring electrodes (22, 24) in order to measure flow in the pipe. a) providing the pipe in a state at least in part filled with a fluid; characterised in that the method further comprises the steps of: b) exciting the first and second measuring electrodes (22, 24) with contradirectional measuring currents, wherein the measuring currents bring about current flow from the first measuring electrodes to the second measuring electrode, and detecting at least one first measured value at each of the first and/or second measuring electrodes (22, 24); c) exciting the first and second measuring electrodes (22, 24) with equidirectional measuring currents, wherein the measuring currents bring about current flow from the first and second measuring electrodes (22, 24) to a first earth electrode or vice versa, and detecting a second measured value at each of the first and/or second measuring electrodes (22, 24); d) ascertaining the fill level of the pipe on the basis of at least the first and second measured values (26, 28) according to steps b) and c), b) exciting the first and second measuring electrodes (22, 24) with contradirectional measuring currents, wherein the measuring currents bring about current flow from the first measuring electrodes to the second measuring electrode, and detecting at least one first measured value at each of the first and/or second measuring electrodes (22, 24); c) exciting the first and second measuring electrodes (22, 24) with equidirectional measuring currents, wherein the measuring currents bring about current flow from the first and second measuring electrodes (22, 24) to a first earth electrode or vice versa, and detecting a second measured value at each of the first and/or second measuring electrodes (22, 24); d) ascertaining the fill level of the pipe on the basis of at least the first and second measured values (26, 28) according to steps b) and c), wherein, in a further step e), a voltage induced in the fluid by a magnetic field is detected by the first and/or second measuring electrodes (22, 24) in order to measure flow in the pipe.
