Abstract

The invention discloses a flow metering device, which relates to the technical field of flowmeters, and is characterized in that the interior of a body is hollow, and two opposite sides of the body are opened; the floater assembly is arranged in the body, and the floater assembly and the body are coaxial. The welding assembly is located on one side of the body and fixedly connected with the body.The filter screen is located in the body and fixedly connected with the inner wall of the body. The floater guide is arranged in the body, and the floater guide and the body are concentric; the floater blocking piece is located in the body, the floater blocking piece and the body are concentric, and a gap is formed between the floater assemblies. The problems that in the prior art, a flowmeter istoo complex in structure, a coupling part often falls off, a floater is prone to being sucked to the wall, and consequently the measurement precision is reduced are solved.

Description

technical field [0001] The invention relates to the technical field of flow meters, in particular to a flow metering device and a usage method. Background technique [0002] The rotameter measures fluid flow according to the principle of throttling, but it changes the flow area of ​​the fluid to keep the differential pressure above and below the rotor constant, so it is also called a variable flow area constant differential pressure flowmeter, also known as a rotameter. In a vertical conical tube that expands from bottom to top, the gravity of the float with a circular cross section is borne by liquid power, and the float can rise and fall freely in the conical tube, moving up and down under the action of flow velocity and buoyancy, and the weight of the float After balancing, it is transmitted to the dial to indicate the flow through the magnetic coupling. [0003] However, existing rotameters such as Figure 6 As shown, it usually includes: indicator components, coupling ...
