Embodiment Construction

[0033] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Such as Figure 1-3As shown, the fluid flow tube 4 of this embodiment has a fluid input pipeline 41 for connecting with the upstream pipeline joint 1 to receive fluid material, a fluid output pipeline 42 for connecting with the downstream pipeline joint to output fluid material, and a connection A double loop line between the fluid input line 41 and the fluid output line 42 . The double loop pipeline includes a first loop connected to the fluid input pipeline 41, a second loop connected to the fluid output pipeline 42, and a loop connected to the first loop and the second loop. The jumper pipeline between the first loop and the second loop is arranged in parallel, specifically, the plane where the first loop is located is parallel to the plane where the second loop is located. The first loop and the second loop are substantially rectangular in s...

Abstract

The invention discloses a fluid flow pipe, a sensor assembly and a Coriolis mass flowmeter. The fluid flow pipe comprises a fluid input pipeline, a fluid output pipeline and a dual-loop pipeline whichis connected between the fluid input pipeline and the fluid output pipeline in series, the dual-loop pipeline comprises a first loop which is connected with the fluid input pipeline and a second loopwhich is connected with the fluid output pipeline, the plane where the first loop is located is parallel to the plane where the second loop is located, and the first loop is connected with the secondloop through a crossover pipeline; the first loop and the second loop are basically in the shape of a rectangle with rounded corners. By forming the first loop and the second loop in the shape of therectangle with rounded corners, the problem that difference value of flow speeds at the inner and outer sides when a fluid material makes a turn is large is solved; meanwhile, during processing, highsymmetry of the dual loops is easily achieved.

Description

technical field [0001] The invention relates to a Coriolis mass flowmeter, in particular to a fluid flow tube, a sensor assembly and a Coriolis mass flowmeter. Background technique [0002] A Coriolis mass flow meter is an instrument that directly and precisely measures fluid flow. The main body of a typical Coriolis mass flowmeter structure uses two U-shaped tubes side by side, allowing the two tubes to vibrate at the same frequency and anti-phase at their resonant frequency, that is, they will move closer or open at the same time. If a fluid is introduced into the tube to flow forward along the tube while the vibrating tube vibrates synchronously, the vibrating tube will force the fluid to vibrate with it. In order to resist this forced vibration, the fluid will give the vibrating tube a reaction force perpendicular to its flow direction. Under this effect called the Coriolis effect, the vibrating tube will produce torsional deformation, and the fluid inlet section and th...
