[0010] 1. This waterproof and easy-to-install industrial instrument places the flowmeter body between two delivery pipes, aligns the first flange and the second flange, and pushes the first flange toward the second flange. At this time, the positioning block is inserted into the connection port, and the arc surface of the plug-in block is forced to be accommodated in the T-shaped groove. The connecting spring is squeezed. When the plug-in block is removed from the connection port, the elastic force of the connecting spring pushes the plug-in block out of the T-shaped groove. The plug-in block can initially position and support the first flange and the second flange, thereby facilitating the subsequent connection between the first flange and the second flange.

After the connecting wire passes through the threading tube, the hexagonal rotating block rotates the movable tube, which drives the rotating ring to move. The rotating ring pushes the elastic arc plate, and the elastic arc plate is forced to move toward the connecting wire. At this time, the elastic arc plate can press the connecting wire tightly, thereby preventing the connection point from being affected by the force when the connecting wire is subjected to force.

[0021] A threading tube 11 is installed on the surface of the flowmeter body 1, and a fixing mechanism for fixing the line is detachably installed on the surface of the threading tube 11. The fixing mechanism includes a mounting tube 12, and the end face of the mounting tube 12 is fixedly connected to an elastic arc plate 13.
