[0026] Furthermore, the diameter of the vent 11 gradually decreases toward the inner side of the axis of the vertical pipe 4. It is wide outside and narrow inside to minimize the escape of gas.

[0027] Furthermore, a rainproof cap 10 is fixed on the vertical pipe 4 at an upper side of the vent 11 .

[0028] Furthermore, an air cavity 14 is provided inside the fixed ring seat 6 , a flange seat 18 is fixedly provided at the bottom of the air cavity 14 , the flange seat 18 matches with the flange in the radar element 7 , and the air hole 19 communicates the air cavity 14 with the interior of the horn 8 .

[0029] Furthermore, connection blocks 2 are respectively provided on the upper and lower sides of the vertical pipe 4 , and a fixing seat 3 is fixedly provided on each connection block 2 .

[0030] Furthermore, the radar element 7 is connected to an external LED display screen to display real-time water level data and water level rise and fall speed.
