Abstract: A method includes: determining a wall temperature of a wall enclosing a lumen of a flow line; determining a density, a viscosity, a thermal conductivity, a thermal capacity, and a pressure differential of a medium to be measured flowing in the line; determining a characteristic number value for the medium, which characterizes a heating of the medium flowing in the line as a result of dissipation and is a function of an Eckert number, a Prandtl number, and a pressure loss coefficient of the line as well as line-specific first, second and third exponents; and determining a temperature of the medium using the characteristic number value and the wall temperature. A measuring system for the method includes: a temperature sensor thermally coupled to a lateral surface of the wall and configured to generate a temperature measurement signal; and an operating electronic system electrically connected to the temperature sensor.

Abstract: The flow measuring system comprises a measuring transducer having a tube arrangement to convey a flowing fluid, an exciter arrangement for forced mechanical oscillations of the tube arrangement, and a sensor arrangement for registering mechanical oscillations of the tube arrangement. The measuring system further comprises a measuring and operating electronics electrically coupled with the exciter arrangement and the sensor arrangement. The measuring system has two driver circuits and two measurement transmitter circuits. The tube arrangement includes two flow dividers and four connected tubes adapted to be flowed through by the measured substance. The exciter arrangement includes two oscillation exciters, and the sensor arrangement includes four oscillation sensors. The first measurement transmitter circuit processes measurement signals from two oscillation sensors and outputs such to the second measurement transmitter circuit The second measurement transmitter circuit processes oscillation measurement signals of the other two oscillation sensors and ascertains total flow measured values.

Abstract: A method is provided for measuring density of a fluid by means of at least one at least sectionally curved measuring tube. The measuring tube is adapted to be flowed through by the fluid and concurrently to be caused to vibrate over a wanted oscillatory length, namely a tube length measured from a first tube end to a second tube end, a length which is greater than a minimum separation of the second tube end from the first tube end. According to the invention, among other things, also a tilt measured value representing an inclination of the at least one measuring tube in the static resting position relative to a local acceleration of gravity is ascertained, in such a manner that such represents an angle of intersection between a direction vector of an imaginary first reference axis (y-axis) and a direction vector of an imaginary second reference axis (g-axis). The first reference axis is so selected that it is perpendicular to an imaginary third reference axis (z-axis) imaginarily connecting the first tube end and the second tube end and points in the direction of a peak of the at least one measuring tube farthest from the third reference axis in the static resting position, while the second reference axis is so selected that it extends through a shared intersection of the first and third reference axes and points in the vertical direction, namely in the direction of the local acceleration of gravity. The tilt measured value is used together with a parameter measured value representing an oscillation frequency of the at least one measuring tube for ascertaining at least one density measured value representing the density of the fluid.
