A sealing ring is arranged on the first half ring block and the second half ring block.

[0008] Furthermore, the first half ring block and the second half ring block are both provided with clamping grooves adapted to the diameter of the signal line.

[0009] Furthermore, the sealing ring is provided with a semicircular hole matched with the diameter of the signal line.

[0010] Furthermore, the first half ring block and the second half ring block are both installed with connecting plates, the connecting plates are fixedly installed with fixing columns, and the fixing columns are connected with second fasteners.

[0023] A connecting member 7 is sleeved on the measuring rod 1, and the connecting member 7 is suitable for sliding along the straight direction of the measuring rod 1. At the same time, the connecting member 7 has a concave groove, and a propeller 8 is rotatably connected to the concave groove. The propeller 8 is suitable for rotating with the water flow, and a first fastener 9 is connected to the connecting member 7. The first fastener 9 is suitable for fixing the propeller 8 on the connecting member 7 in a non-working state;

[0024] A tail wing 6 is threadedly connected to one end of the connecting member 7 away from the propeller 8. The tail wing 6 is suitable for fixing the connecting member 7 on the measuring rod 1. At the same time, the tail wing 6 is suitable for keeping the propeller 8 balanced and facing the direction of the water flow. A direction mark 4 is sleeved on the measuring rod 1. The direction mark 4 is consistent with the direction of the propeller 8, so that the user can judge the position of the propeller 8.

[0025] A terminal 10 is fixedly mounted on the connector 7, and a signal line 12 is sleeved on the terminal 10. The signal line 12 has a connection coil 13 and a set of connectors.
