Title:
FLOWMETER FOR SEWAGE CONDUIT
Document Type and Number:
WIPO Patent Application WO/2021/145494
Kind Code:
A1
Abstract:
Disclosed is a flowmeter for a sewage conduit. The flowmeter for a sewage conduit according to the present invention comprises: a plurality of groups of fluid guide units (10) which are inserted into a sewage conduit (C) and are formed to face one another at constant intervals from the lowest water level adjacent to the bottom surface of the sewage conduit (C) to a level less than the highest water level, wherein the fluid guide units (10) protrude in parallel with one another from the inner circumferential surface in the flow direction; a first body unit (1a) including a pair of ultrasonic transducers (14) which are embedded in an end of a protruding side of the fluid guide unit (10), designed in a V-method such that ultrasound waves radiated from one ultrasonic transducer are reflected by the facing fluid guide unit (10) and reach another ultrasonic transducer, and formed so that a separating distance therebetween increases from the low water level to the high water level; a second body unit (1b) which is a part exposed out of the sewage conduit (C) by extending from the first body unit (1a) inserted in the sewage conduit (C) toward a manhole side, includes an opening unit (16) that is formed by cutting the upper end at a certain angle, and is formed as the fluid guide units (10) formed in the first body unit (1a) are extended; and a water level measurement sensor unit (18) which is fixed in the manhole on the outside of the sewage conduit (C) and measures the water level by radiating ultrasonic waves to the opening unit (16) of the second body unit (1b) and receiving the ultrasonic waves reflected from the water surface.
