Problems solved by technology

According to my country's national conditions, the problem of water supply quality not only invalidates the mechanical flowmeter, but also invalidates the ultrasonic flowmeter. Transmitting and receiving faults occur in the meter, and in extreme cases: after the ultrasonic transmission, it cannot reach the receiver at all

Abstract

The invention relates to a multistreaming high-precision rotary ring type flow sensor which comprises a flow meter shell, a flow meter top cover, an upper impeller shell component, an impeller component, a lower impeller shell component, a filter screen, a diversion component, an external measuring room and an inner measuring room, wherein a fluid flows into from the water inlet of the flow meter shell, changes direction along the slope of the diversion component to flow upwards, then flows through the fan-shaped hole of the filter screen to the external measuring room, enters into the wedge-shaped water inlet of the upper impeller shell component along the diagonal line direction, enters into the inner measuring room through the wedge-shaped water inlet, and forms multiple streams so as to uniformly push the impeller component to rotate; and at the same time, the fluid changes the movement direction to move downwards into the center hole of the filter screen, then flows out from the water outlet of the flow meter shell through the center hole of the diversion component. In the invention, the multistreaming principle is utilized, so that the momentary rotation speed of an impeller can correspond to the momentary flow speed of the fluid flowing through the measuring rooms more truly, and the flow characteristic of a flow meter is improved, and the flow measurement accuracy, repeatability and reproducibility and stability are improved.

Description

(1) Technical field: [0001] The invention relates to a multi-beam high-precision rotor-type flow sensor and a working method thereof, which are particularly suitable for heat meters and cold and heat meters for metering and charging of central heating and central air-conditioning of buildings. (2) Technical background: [0002] With the rapid development of my country's national economy, the demand for resources is increasing. After the financial crisis in 2008, energy and energy conservation have become major global issues, and energy conservation has also become a basic national policy of the country. For example, my country's per capita water resources are only 2,710 cubic meters, about 1 / 4 of the world's per capita share, ranking 88th in the world. Some foreign countries have already adopted water recycling measures for industrial water use, and the water reuse rate is as high as 70% to 90%, while most cities in China still stay at the level of 20% to 50%. Due to the ba...
