The GBK-101 well depth gauge with scale and sound is used to measure the water level in logging, drilling, or pressure measuring tubes. The instrument consists of a steel tape ruler with built-in wires, a probe, an audible and visual indicator circuit, and a flat ruler scroll. The probe at the front end of the level ruler is equipped with a needle type water level sensor. When the probe contacts the water surface, it will trigger the sound and light alarm inside the reel, and indicate the depth of the liquid level from the orifice through the scale on the level ruler.
The cross-section of the straightedge is designed in the shape of a dog bone, which can prevent it from adhering to the wet inner wall of the logging or drilling hole and affecting the measurement. The high-quality scroll is made of aluminum alloy plate and coated with baking paint on the surface, which has good moisture and corrosion resistance.
