Embodiment Construction

[0015] The invention provides a high-precision rotor flowmeter, which takes into account the accuracy of the sensor measurement and the anti-damage function, and is used for measuring the flow rate of the pipeline transmission medium (such as liquid or gas). The structure is simple and the range is not limited. A product that fills a gap in the market.

[0016] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] The rotameter provided by the present invention includes a flow tube 10, an electronic chamber 20, a waveguide rod 30, a magnetic float 40, and a measuring chamber 50. The measuring chamber 50 is a tapered pipe installed in the flow p...

Abstract

The invention discloses a high-precision rotor flowmeter, which includes a flow tube, an electronic chamber, a waveguide rod, a magnetic float and a measurement chamber, the waveguide rod is connected with the electronic chamber, and the magnetic float is sleeved on the waveguide rod above, and the magnetic float and waveguide rod are located in the measurement chamber; the measurement chamber is installed in the flow tube upside down. The invention replaces the center guide rod of the existing metal bar with the waveguide rod, and uses the magnetic float, so that the rotameter has a more sensitive response and more accurate measurement, and the stroke of the magnetic float is not affected by the magnetic force of the existing rotating magnet. limit, increasing the range of the rotameter.

Description

technical field [0001] The invention relates to flow detection technology, in particular to a rotameter. Background technique [0002] Rotor flowmeter, also known as float flowmeter, is a kind of variable area flowmeter. In a vertical tapered tube that expands from bottom to top, the float is set on the center guide rod of the metal bar, and the gravity of the float is borne by the liquid power. , so that the float can rise and fall freely in the conical tube. When measuring, it moves up and down under the action of flow velocity and buoyancy, and after balancing with the weight of the float, it is transmitted to the dial to indicate the flow rate through magnetic coupling. [0003] The rotameter is the most widely used type of flowmeter after the differential pressure flowmeter, especially in small and micro flow. However, during the measurement, there are many links in the transmission and change of the float position signal. It is coupled to the rotating magnet through ...
