The AT304 steel ruler water level gauge triggers a signal by the probe contacting the water surface, thereby reading the water level depth. During measurement, slowly insert the probe into the tube. When the water resistance contact point at the bottom of the probe touches the water surface, the receiving system will be connected and a signal (such as a beeping sound or an indicator light turning on) will be emitted; when the probe leaves the water surface, the system will automatically shut off.

It is mainly composed of a stainless steel probe with water resistance contact points inside, a steel ruler cable, a receiving system (including a speaker to emit signal, a peak indicator, and an indicator light), and a winding reel (used to store the steel ruler cable and place the receiving system and batteries). This product is corrosion-resistant, durable, safe to use, and convenient for reading. It is usually used to measure the water level in wells, boreholes, and water level tubes (it can be used during the construction period and also as a long-term safety monitoring device for the project).
