The wireless receiver 3 has a wireless receiving circuit 31 connected to a warning circuit 32 and a power source 33, and is connected to the power switch 34 and its indicator light 35 and the warning light 36.

When the level measurement is performed on site, as shown in the third, fourth and fifth figures, the worker first fixes the liquid level detector 2 and the detection section 11 of the communication tube 1 to the position to be measured. The height of the fixing portion 26 can be positioned by the nail or the hook type fixing member 27, and then the opening and closing members 15 are opened to form the ventilation, and then the worker moves the communication tube 1 upwards near the height of the other position to be measured. In the measuring section 12, when the liquid level sensing circuit 21 senses that the liquid levels 131, 132 at both ends of the communication pipe 1 reach the horizontal state of the height to be measured, the liquid level 131 of the detecting section 11 of the communication pipe 1 has driven the floating ball 14 Rising and pushing the two conductive contacts 211, 212 into contact with each other to drive the wireless transmitting circuit 22 to transmit signals to the wireless receiving circuit 31 of the wireless receiver 3, so that the warning circuit 32 (such as a speaker) outputs sound effects, and can cooperate with the warning The lamp 36 is illuminated and immediately informs the staff to correctly mark the level position according to the mark 16 and/or the liquid level 131, 132, which makes the on-site level measurement easier and faster, saves manpower and man-hours, and is convenient to carry. .

In another embodiment shown in the sixth and seventh embodiments, the connecting pipe 1 and the detecting section 11 and the measuring section 12 are collectively configured as a unitary pipe body, and the movable pipe clamp type can be set at both ends of the communicating pipe 1. The closing member 17 is used to open the communication tube 1 to maintain ventilation during measurement use (see the seventh figure).

In summary, the present invention can solve the lack of the use of the conventional level measuring tube. The key technology is that the connecting tube 1 automatically detects the liquid levels 131, 132 by the liquid level detector 2, and drives the wireless via the wireless transmitting circuit 22. The receiver 3 causes the warning circuit 32 to output a sound effect to inform the staff to correctly mark the horizontal position according to the mark 16, so that the on-site level measurement is simpler and faster, saves manpower and man-hours, is convenient to carry and use, and proposes a new patent application according to law. .
