Abstract

The invention relates to a vertical single impeller type flow rate sensing device, which comprises a single impeller, a group of impeller frame, an impeller shaft, a pipe section and a flow rate sensing circuit, wherein the impeller shaft is arranged at the center of the single impeller, the impeller frame is used for fixing the impeller in the pipe section, a plurality of magnets or metal sheets are placed outside the impeller, the outer wall of the pipe section is provided with the flow rate sensing circuit containing a magnetic sensitive element or the flow rate sensing circuit containing an inductor, the flow rate sensing circuit containing the magnetic sensitive element corresponds to the magnets, flow rate sensing circuit containing the inductor corresponds to the metal sheets, the rotation direction of the single impeller is vertical to the water flow direction, and the pipe section is made of plastics. The vertical single impeller type flow rate sensing device has the advantages of few transmission mechanisms, small pressure loss and small startup flow rate, is easy to realize water prevention and moisture prevention, and the flow rate sensing circuit is completely isolated from water.

Description

(1) Technical field [0001] The invention relates to the field of water meter flow measurement, in particular to a vertical single impeller type flow sensor device. (2) Background technology [0002] The water meter is a tool for trade settlement, which is directly applied to the measurement of industrial and agricultural production and drinking water for residents, and is the basis for the settlement of water trade. Therefore, water meters are required to be accurate in measurement, easy to read, and fair in calculation. In recent years, with the rapid development of the economy, water resources have become increasingly scarce, and people's requirements for the quality of drinking water have gradually increased. It can be seen that the status of water meters is constantly rising, especially for large-caliber water meters used in industrial and agricultural production, requiring simpler structures, more accurate measurements, and higher sensitivity. However, due to too many ...
