Document Type and Number:

WIPO Patent Application WO/2020/107334

Kind Code:

A1

Abstract:

An electromagnetic flow meter (4000) and a plant protection unmanned aerial vehicle comprising same. The electromagnetic flow meter (4000) comprises: a housing (8) having an accommodation space; a support (1) provided in the accommodation space; a pipeline (2) provided in the support (1), wherein both opening ends of which expose the support (1); two electrodes (3) provided opposite to each other at both sides of the support (1), wherein detection ends of the two electrodes (3) respectively penetrate side walls of the support (1) and the pipeline (2), and then contact with the liquid that flows through the pipeline (2); the detection ends of the two electrodes (3) are provided opposite to each other; two signal acquisition boards (4) provided at the same side of the support (1) corresponding to the two electrodes (3), and used for acquiring signals of the electrodes (3) at the corresponding sides; and two coil components (5) provided opposite to each other at the other two sides of the support (1). At least one signal acquisition board (4) is provided with a ground socket (61). The electromagnetic flow meter (4000) further comprises a ground connection member (500) which penetrates the ground socket (61) to be fixed on an inner side wall of the housing (8) so that the housing (8) is grounded.
