Title:
ELECTROMAGNETIC FLOWMETER, SPRAYING APPARATUS AND MOVABLE PLATFORM
Document Type and Number:
WIPO Patent Application WO/2021/051273
Kind Code:
A1
Abstract:
An electromagnetic flowmeter, comprising: a housing (101); a pipe group, which is arranged in the housing (101) and which comprises at least two pipes (102) which are provided at an interval; a pair of excitation coils (103), which are used for used applying a magnetic field to a fluid flowing through the at least two pipes (102), the pair of excitation coils (103) being arranged on two sides of the pipe group, respectively; and at least two pairs of electrodes (104), which are used for detecting the electrical potential induced by the fluid in the pipes (102) flowing in the magnetic field. Each pair of electrodes (104) comprises two electrodes (104) which are oppositely provided on a side wall of each pipe (102) respectively, and a detection end of each electrode (104) passes through the side wall of the pipe and is capable of making contact with the fluid flowing through the pipe. The described electromagnetic flowmeter integrates two or more pipes (102), and detects the flow of fluid in each pipe respectively; in addition, the flow need not be calibrated for each pump, and the structure is compact/lightweight. Also provided are a spraying apparatus and a movable platform.
