Application

The SWJ-80 steel ruler is the most accurate method for measuring the water level. It is usually used for measuring the water level in wells, drill holes and water level pipes. It is especially suitable for the observation of groundwater level in hydropower projects or dams of earth-rock dam bodies. Infiltration inspection of the line. This instrument can be used during construction or as a long-term safety monitoring of the project.



Steel ruler cable part

the steel ruler and the wire are combined into one by the plastic process, which prevents the steel rule from rusting and simplifies the operation process. The reading is more convenient and accurate.



Users must pay attention to two points when reading

A) When the touch point of the touch probe touches the water surface, the sounder will make a sound, the indicator light will turn on, and the voltmeter hands will turn. At this point, the steel ruler cable should be slowly put in order to carefully find the exact position of the pronunciation or indication moment and then read out the depth dimension of the point from the orifice.

B) The accuracy of the reading is determined by the timely judgment of the buzzer or the starting position of the indication. The accuracy of the measurement is related to the proficiency of the operator. Therefore, repeated practice and operation are required.



maintenance

After the measurement, the probe and the steel cable must be wiped cleanly, and the steel cable should be neatly wound on the reel and then placed in the cabinet.

Do not bend the measuring cable, especially near the side of the head to prevent damage.
