Description

Technical Field

[0001] The utility model belongs to the technical field of sediment measurement, and particularly relates to a metal rotameter for sediment measurement. Background Technique

[0002] Sediment measurement, as an important item in hydrological measurement, refers to the technology of observing and measuring the form, quantity and evolution process of sediment moving with water flow in a basin and water body. When a user measures sediment flow, a metal rotameter needs to be used for measurement. The metal rotameter, also known as a metal float flowmeter, is a variable area flowmeter mainly used for measuring the flow rate of fluids. Its working principle is based on the corresponding relationship between the position height of a float (rotor) in a conical tube and the flow rate. Specifically, when the measured fluid flows through the annular cross-section between the rotor and the conical tube wall, a force will be generated on the rotor, and the magnitude of this force changes with the flow rate. When the flow rate is large enough, the generated force will lift the rotor and make it rise. When the force generated by the flowing measured fluid on the rotor is exactly equal to the weight of the rotor in the fluid (referred to as the displayed weight), the rotor is in a balanced state under the action of force and stays at a certain height. Therefore, by observing the position height of the rotor in the conical tube, the corresponding flow rate value can be obtained.

[0003] When the traditional metal rotameter is installed between two pipelines, the user needs to use tools and multiple bolts to fix the flanges at both ends of the metal rotameter to the two flanges on the two pipelines respectively, so as to fix the metal rotameter between the two pipelines. This installation method consumes a long installation time and has low work efficiency. In view of this, we propose a metal rotameter for sediment measurement. Content of the Utility Model
