Abstract
A measurement module determines a fluid quantity which relates to a property of a fluid located in or flowing through a measurement tube. The measurement module contains a base body, a control device and first and second oscillation transducers fastened at a distance from one another on the base body. The first and/or the second oscillation transducer is controlled by the control device to excite an oscillation of a side wall of the measurement tube when a contact face of the measurement module is coupled to the side wall of the measurement tube directly or via a coupling layer. The oscillation of the side wall excites compression oscillations of the fluid, which are conducted through the fluid to the respective other oscillation transducer and recorded the control device to determine a measurement quantity. The fluid quantity can be determined by the control device in dependence on the measurement quantity.
