Title:
ELECTROMAGNETIC FLOWMETER AND PLANT-PROTECTING UNMANNED AERIAL VEHICLE HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2020/107324
Kind Code:
A1
Abstract:
An electromagnetic flowmeter (4000) and a plant-protecting unmanned aerial vehicle having the electromagnetic flowmeter (4000). The electromagnetic flowmeter (4000) comprises: a support frame (1); a pipeline (2) disposed at the support frame (1), two open ends of the pipeline (2) being exposed by the support frame (1); two electrodes (3) disposed opposite to each other at two sides of the support frame (1), wherein detection ends of the two electrodes (3) pass through side walls of the support frame (1) and the pipeline (2), respectively, and can make contact with liquid flowing in the pipeline (2), and the detection ends of the two electrodes (3) are disposed opposite to each other; two signal acquisition panels (4), the two signal acquisition panels (4) and the two electrodes (3) being correspondingly disposed at the same side of the support frame (1), and the signal acquisition panels (4) being used to acquire signals from the electrodes (3) at the side corresponding thereto; two coil components (5) being disposed opposite to each other at another two sides of the support frame (1); and a control board (6) electrically coupled and respectively connected to the two signal acquisition panels (4), and used to obtain, according to signals collected by the two signal acquisition panels (4), a flow rate and/or velocity of the liquid flowing in the pipeline (2), wherein the control board (6) and one of the signal acquisition panels (4) are integrated with each other and disposed on the same circuit board. The electromagnetic flowmeter (4000) has a compact design and reduced size, is light weight, and is applicable to plant-protecting unmanned aerial vehicles for performing spraying operations.
