Application features:
Steel gauge water level gauge is the most accurate method to measure water level. It is usually used to measure the water level of Wells, boreholes and water level pipes. It is especially suitable for the observation of underground water level in hydropower projects or the manual inspection of dam infiltration line of upper rock dam. This instrument can be used not only during construction, but also for long-term safety monitoring. Comply with the technical specification for safety monitoring of shangshi dam (sl60-94). Principle of structure:
The measurement and reading of water level variation consists of two parts:
1. The buried part of underground materials, the composition of water level pipe and bottom cover (purchased separately);
The ground receiving instrument -- a steel gauge water level gauge, which is composed of a probe, a steel gauge cable, a receiving system and a winding coil, etc.
L. Probe part: made of stainless steel, with water-resistance contact points installed inside. When the contact contacts the water surface, the receiving system will be connected, and when the contact leaves the water surface, the door will be moved to close the receiving system.
2, steel ruler cable part: by the steel ruler and wire with plastic technology combined for one, not only prevent steel ruler corrosion, and simplify the operation process, measurement and reading more convenient, accurate.
3. Reception system: it is composed of sound device and peak indicator. The sound device emits continuous beeping sound from the buzzer, and the peak indicator is voltmeter pointer indicator.
4. Winding disc: the mountain winding disc and bracket are composed. 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.
5, water level pipe (another purchase) : made of PVC engineering plastics, my factory production, including the main and connection pipe, the main internal diameter phi 45mm, 53mm outside diameter, connection pipe internal diameter phi 53mm, the external diameter phi 63mm, connection pipe sleeve in two sections of the main connection, plays a role in connection with the fixed role.
16, the supervisor has four rows of hole phi 7mm, so that the water into the pipe smoothly, buried, should be in the card tube outsourcing geotextile, and fixed, has a filtering effect.
6. Bottom cover (purchased separately) : it is made by injection molding and is installed at the bottom and top of the water level pipe in our factory. It can effectively prevent mud and sand from entering or foreign matter falling into the pipe, so as to avoid affecting the measurement.
