    Abstract: A measuring arrangement comprising a pipe (2) with a pipe axis (B) and an ultrasonic, flow measuring device (1), wherein the ultrasonic, flow measuring device (1) has a sensor unit (3), which is fixed in a hole (16) in the pipe (2), which hole (16) is introduced essentially perpendicularly to the pipe axis (B) into the pipe wall, wherein the sensor unit has a rail (18) or a rod with a longitudinal axis (A), wherein the rail or the rod bears at least two ultrasonic transducers (4 and 13), which define a signal path, wherein the signal path extends parallel to or on the longitudinal axis (A) of the rail (18) or of the rod, and wherein the signal path is tilted from a perpendicular connecting line (C) between the center point of the hole and the pipe axis (B), as well as an ultrasonic, flow measuring device.

    Abstract: A measuring system comprises: a measuring transducer; transmitter electronics; at least one measuring tube; and at least one oscillation exciter. The transmitter electronics delivers a driver signal for the at least one oscillation exciter, and for feeding electrical, excitation power into the at least one oscillation exciter. The driver signal, has a sinusoidal signal component which corresponds to an instantaneous eigenfrequency, and in which the at least one measuring tube can execute, or executes, eigenoscillations about a resting position. The eigenoscillations have an oscillation node and in the region of the wanted, oscillatory length exactly one oscillatory antinode. The driver signal has, a sinusoidal signal component with a signal frequency, which deviates from each instantaneous eigenfrequency of each natural mode of oscillation of the at least one measuring tube, in each case, by more than 1 Hz and/or by more than 1% of said eigenfrequency.

    Abstract: A measuring arrangement, comprising: a pipe with a pipe axis and an ultrasonic, flow measuring device. The ultrasonic, flow measuring device has a sensor unit, which is fixed in a hole in the pipe, which hole is introduced essentially perpendicularly to the pipe axis into the pipe wall. The sensor unit has a rail or a rod with a longitudinal axis. The rail or the rod bears at least two ultrasonic transducers, which define a signal path, wherein the signal path extends parallel to or on the longitudinal axis of the rail or of the rod, and wherein the signal path is tilted from a perpendicular connecting line between the center point of the hole and the pipe axis. In addition, an ultrasonic, flow measuring device is noted.
