Problems solved by technology
[0002] At present, the flowmeters used by plant protection drones have the following problems: the detection accuracy is easily affected by pesticide corrosion, impurities, and the cooperation between the cavity and the rotor. Inconsistent, difficult to achieve the purpose of precise spraying
In addition, most of the flowmeters on the market are not detachable. The flowmeter casing is fixed by screws, and it is troublesome to replace the rotor. In actual application scenarios, the flowmeter rotor is damaged or the flow rate is not smooth, so it is difficult to clean and replace.

The invention discloses a high-precision flowmeter. The flowmeter comprises a flow meter body including an inflow cavity, an outflow cavity, an impeller, a sensor and an upper cover, wherein the inflow cavity is used for positioning the impeller, is cylinder-shaped and is provided with a water inlet at one side; the outflow cavity is provided with a water outlet at side; a flow path is formed between the inflow cavity and the outflow cavity, and the flow path is arranged along the axial direction of the inflow cavity from front to back; the impeller is disposed in the inflow cavity; the sensor is arranged on the outer side of the inflow cavity and matched with the impeller; the upper cover is used for closing the inflow cavity and positioning the impeller. The flowmeter has the advantages of increasing the detection precision of the spraying amount of pesticide, improving the working efficiency, and realizing the precise spraying and the intelligent spraying by adopting the axial double-cavity design. A cavity body of the flowmeter is made by the use of high-strength aviation aluminum to ensure the rotation precision between the impeller and a flowmeter cavity body shaft. The entire flowmeter is made by the use of the aviation aluminum, thus the corrosion resistance is enhanced, the service life is ensured, and the detection precision and repeatability precision of the flowmeter are ensured.
