The bending part 360 may be provided in the form as shown in FIG. 7, which will be described later.

The load unit 300 of the ultrasonic flow system capable of selectively adjusting horizontal radians according to the present invention allows a predetermined bending angle of the body portion 350 and the movement portion 320 to be formed by the weight of the flow sensing unit 500 I can.

In addition, the trapping unit 410 may increase a pressing force that presses the upper portion of the manhole by the load from the outside applied to the upper portion and the load of the flow meter provided to the flow sensing unit 500.

The bending angle formed in the bending part 360 may be formed by the weight of the flow sensing unit 500, and the bending angle may be maintained by the weight of the flow sensing unit 500.

The trapping unit 410 also increases the pressing force that presses the upper portion of the manhole 1 by the load of the upper portion and the load of the flow sensing unit 500, so that the flow sensing unit 500 is provided, thereby making the upper portion of the manhole more rigid. Can be fixedly mounted in.

The bending part 360 of the ultrasonic flow system capable of selectively adjusting horizontal radians according to the present invention may include a protruding part 361 and a folded part 362 formed to protrude toward an outer circumferential surface.

The bending part 360 may have a bending angle according to the degree of folding of the point force part 362.

As shown in Fig.7, the bending part 360 is composed of a protrusion 360 protruding from the outside of the bending part 360 and a folded part 362 forming a fold in the inside of the bending part 360. I can.

In the case of the protrusion 360, the folded portion 360 may be further protruded by folding, and the folded portion 360 selectively forms the degree of folding as shown in FIG. 7(b) so that it can be bent. I can.

That is, the bending portion 360 is folded through the folded portion 360, and the bending angle may be selectively displayed depending on how much and at which position the folded portion 360 is folded.

The scope of the rights of the present invention is determined by the matters described in the claims, and the parentheses used in the claims are not described for selective limitation, but are used for clear elements, and descriptions in parentheses are also interpreted as essential elements. Should be.
