[0035] Embodiment: During installation, one end of the measuring tube 1 with the arc groove 5 is butted with the water inlet pipe, and the other end is butted with the water outlet pipe to ensure that the pipe joints are well sealed.

[0036] Insert the mounting seat 3 into the measuring tube 1 and securely fix it inside the measuring tube 1 by appropriate means (such as bolting or welding), ensuring that the axis of the mounting seat 3 coincides with the axis of the measuring tube 1 so that the paddle wheel 4 rotates smoothly.
