Abstract: Each of two flow tubes assumes an arcuate shape consisting of a central arcuate segment and two linear segments located on opposite sides of the central arcuate segment. The inside diameter of the flow tubes and the linear distance between end points of each of the flow tubes are determined on the basis of a target pressure loss arising from passage of a fluid to be measured through a manifold and the flow tube at the maximum flow rate, a target time phase difference between sine wave outputs from vibration sensors at the maximum flow rate, and a target natural frequency of the flow tubes. The length of the linear segments is selected so as to reduce thermal stress induced from an abrupt change in the temperature of the fluid to be measured, and the shape of the flow tubes is determined so as to reduce the vertical height of the flow tubes, so long as the thermal stress is substantially constant even when the length of the linear segments is varied.

Deflecting pins, which are provided with grooves in which carrier prisms are arranged, are introduced in pairs into recesses in a housing in a plane located in parallel to the mounting surface of the element. The carrier prisms have wedge surfaces, which are slidingly guided in the grooves of the deflecting pins. The deflecting pins are controlled by pistons, which are arranged in the same plane but at right angles to the deflecting pins. The forces are transmitted beginning from the piston via the deflecting pins to the carrier prisms and then to the self-centering slides, which are connected to the carrier prisms and which move the clamping jaws.
