 The steel ruler water level gauge is composed of probe, steel ruler cable, receiving system and winding coil.

1. Probe part: made of stainless steel, with water resistance contact point installed inside. When the contact contacts the water surface, the receiving system will be connected. When the contact leaves the water surface, the receiving system will be automatically closed.

2. Steel ruler cable part: the steel ruler and wire are combined by plastic technology, which not only prevents the steel ruler from rusting, but also simplifies the operation process, making the measurement and reading more convenient and accurate.   3. Receiving system part: it is composed of loudspeaker and peak indicator. The loudspeaker sends out continuous beeping sound by buzzer, and the peak indicator is the pointer indicator of voltmeter. The two can be selected by turning the switch. No matter what kind of receiving system is used, the measuring and reading accuracy is consistent.
