Summary: Szswj-8090 steel gauge water level gauge is the most accurate method to measure the water level. It is usually used to measure the water level in Wells, boreholes and water level pipes. It is especially suitable for the observation of underground water level in hydropower projects or manual inspection of dam body infiltration line of earth-rock DAMS. This instrument can be used not only during construction, but also for long-term safety monitoring. It conforms to the technical specifications for safety monitoring of earth-rock DAMS.

Principle of structure: The measurement and reading of water level variation consists of two parts: 1. The buried part of underground materials shall consist of water level pipe and bottom cover (purchased separately); The ground receiving instrument -- steel gauge water level gauge is composed of measuring head, steel gauge cable, receiving system and winding coil. 3.1 probe part: made of stainless steel, with water-resistance contact points installed inside. When the contact touches the water surface, the receiving system will be connected, and when the contact leaves the water surface, the receiving system will be automatically closed. 3.2 steel ruler cable: the steel ruler and wire are combined by plastic technology to prevent corrosion of the steel ruler and simplify the operation process, making the measurement and reading more convenient and accurate. 3.3 reception system: it is composed of a sound device and a peak indicator. The sound device emits continuous beeping sound from a buzzer, and the peak indicator is a voltmeter pointer indicator. The two can be selected by toggle switch. 3.4 winding disc: it is composed of winding disc and bracket, the receiving system and battery are all placed in the core cavity of winding disc, and the steel ruler cable is wound outside the cavity. 3.5 water pipe (available separately) : made from PVC engineering plastics, I plant production, including the head and connection pipe, head diameter Φ 45 ㎜, outer diameter Φ 53 ㎜, connecting pipe diameter Φ 53 ㎜, diameter 63 ㎜ Φ, connecting pipe set in two head, joint fixed plays a connecting role.
