Abstract: A mass flowmeter is described and depicted that operates according to the Coriolis principle, with a straight Coriolis tube that conducts the flowing medium, with an oscillation driver, assigned to the Coriolis tube and which excites the Coriolis tube, with two detectors assigned to the Coriolis tube and which register Coriolis forces, or Coriolis oscillations caused by Coriolis forces, and with shell that encloses the Coriolis tube. The mass flowmeter has a notably smaller total length relative to the nominal length of the Coriolis tube than mass flowmeters made according to the prior art because the Coriolis tube is flexibly mounted to an inlet and outlet in the shell.

Abstract: An ultrasonic flowmeter for flowing media, has a measuring tube and at least one ultrasonic transducer, the ultrasonic transducer being installed in contact with the flowing medium in a transducer pocket of the measuring tube. The flowmeter eliminates the disadvantages and problems present in the known ultrasonic flowmeters, caused by eddies generated by the transducer pocket, by providing the transducer pocket with a grid having a mesh, in which the grid is located at the entrance side of the transducer pocket.

Abstract: A volume flow meter for flowing media that works on the transit-time principle includes a conduit measurement section carrying the flowing medium, two ultrasonic transducers arranged on opposite ends of the conduit measurement section sending ultrasonic signals into the flowing medium and/or receiving them from the flowing medium and a control and evaluation circuit. The ultrasonic transducers send ultrasonic signals into the flowing medium via thermally insulating ultrasonic waveguides. The control and evaluation circuit determines the volume flow based on the difference between the total transit time of the ultrasonic signals between the ultrasonic transducers and the sum of the transit times of the ultrasonic signals in the ultrasonic waveguies.

Abstract: A mass flow meter for flow media which works on the Coriolis Principle, has a straight Coriolis pipe carrying the flow medium, an oscillator acting on the Coriolis pipe and two transducers detecting Coriolis forces and/or Coriolis oscillations based on Coriolis forces. The Coriolis pipe also carries mass bodies and is arranged inside of a housing or compensation cylinder. The mass flow meter improves the measurement result that can be obtained by increasing the stiffness of the Coriolis pipe for the excitation mode, preferably by including a reinforcing spring which acts on Coriolis pipe to increase the pipe stiffness for the excitation mode.
