Problems solved by technology

[0003] The common rotameters are designed with a simple structure of a single tapered tube. When measuring, repeated measurements are required to give a relatively stable value. Moreover, the flowmeter with this simple structure vibrates greatly when it is connected to the water pipe. Greatly affects the accuracy of measurement and needs to be improved

Embodiment Construction

[0018] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0019] Such as figure 1 The shown embodiment of a new type of rotameter of the present invention includes a body, the body includes two separate measuring tubes 1 that are butted up and down, and a sealing ring 2 is provided at the butt joints, and the measuring tubes 1 are from The tapered tube that gradually expands from bottom to top is provided with a connecting tube 3 at the upper end of the upper measuring tube 1 and at the lower end of the lower measuring tube 1, and a stabilizing tube 4 is sleeved outside the body, and the stabilizing tube 4 includes a cylindrical outer shell, and the upper and lower ends of the stability tube 4 are also provided with...

Abstract

The invention discloses a novel rotor flow meter which comprises a body. The body comprises two individual measuring pipes which are butted to each other in the up-down directions, a sealing ring is arranged at a butt joint, the measuring pipes are tapered pipes which are gradually expanded from bottom to top, connecting pipes are arranged at the upper end of the upper measuring pipe and the lowerend of the lower measuring pipe, a stable pipe further sleeves the body and comprises a cylindrical shell sleeve, guide connecting seats for being connected with measured fluid pipes are further arranged at the upper end and the lower end of the stable pipe, and the inner sides of the guide connecting seats are clamped with the connecting pipes and are communicated with the connecting pipes. Thenovel rotor flow meter has the advantages that the two tapered pipes are butted to each other, accordingly, two flow numerical values can be simultaneously measured and can be simultaneously analyzed,the measurement and analysis time can be shortened, and measurement links can be reduced; two ends of the body can be stably connected with each other by the additional stable pipe, accordingly, vibration can be reduced to a great extent, the test stability further can be improved, and the service life of the body further can be prolonged.

Description

technical field [0001] The invention relates to the technical field of flow meters, in particular to a novel rotameter. Background technique [0002] The rotameter is the most commonly used flowmeter in industry and laboratories. It has the characteristics of simple structure, intuitive, small pressure loss, convenient maintenance and so on. The rotameter is suitable for measuring the small flow through the pipe diameter D<150mm, and it can also measure the flow of corrosive media. When in use, the flowmeter is generally installed on a vertical pipe section, and the fluid medium passes through the rotameter from bottom to top. The specially designed rotameter can be installed horizontally or vertically. [0003] The common rotameters are designed with a simple structure of a single tapered tube. When measuring, repeated measurements are required to give a relatively stable value. Moreover, the flowmeter with this simple structure vibrates greatly when it is connected to...
