Main specification:

Working principle:

The measurement of the water level by the following two parts:1. Underground material, it is composed by water level pipe and bottom cover (not include in the system, it is need purchased separately)

Ground receiver-ruler water level meter, it is composed by detect head, ruler cable, receiver system and cable reel.

Detect head: made by steel, inside is a water resistance contact point. When the contact point contact water, the receiver system will open, and when the contact point leave the water, the receiver system will close.

Ruler cable: it made by ruler and cable, and use plastic technology keep them together, and avoid the steel corrosion and simple the operation, make the read more convenient and accurate.Receiver system: it is composed by sounder, indicate light and peak value indicator, peak value indicate is voltage indicate.

Use method:

In measuring, make the cable reel rotate and push the power button, put the detect head in the water pipe, put the ruler cable in hand and make it drop slowly. When the detect head contact point contact water, the receiver system buzzer will sound. Then you can read the data of the ruler cable and can know the water level.(if the surrounding voice is loudly, maybe you can hear buzzer, so you can observe the indicate light and voltage meter)
