Overview:
The new steel ruler water level gauge provides a method for measuring water level * *, which is usually used to measure the water level in wells, boreholes, and water level pipes. It is particularly suitable for observing groundwater level in hydropower projects or manually inspecting the seepage line of earth and rock dams. This instrument can be used during construction and can also be used for long-term safety monitoring of projects. Complies with the technical specifications for safety monitoring of earth rock dams.
Advantages:
1. The new metal bracket of Hengmei Technology is more sturdy, which increases fatigue resistance in severe cold and heat, and friction operation cannot withstand heat melting.
2. Add 200 fine threads to the probe to prevent it from falling off. The probe is made of SUS stainless steel material and made of 316l metal to prevent false alarms and resist corrosion from brine, seawater, and alkaline water.
3. The tensile strength of the steel ruler is 5 times that of the regular model.
4. The power on self-test switch is made of SUS metal material, with a press life of more than 50000 times, and can be used directly with one click power on.
5. The buzzing warning sound has been increased to 100 decibels, and the explosive flashing indicator light has made the prompt clearer and more clear, making the operation simpler.
6. The battery does not need to be replaced during charging, allowing outdoor activities to avoid regrets due to power shortages.

Principle and structure:
The measurement of water level changes consists of two main parts:
1. The buried part of underground materials consists of a water level pipe and a bottom cover (to be purchased separately)
2. Ground receiving instrument - steel ruler water level gauge, composed of measuring head, steel ruler cable, receiving system, and winding reel, etc.
Probe section: Made of stainless steel, with water resistance contact points installed inside. When the contact points come into contact with the water surface, the receiving system will be connected. When the contact points leave the water surface, the receiving system will be closed.
Steel ruler cable section: The steel ruler and wire are combined into one using plastic technology, which not only prevents corrosion of the steel ruler but also simplifies the operation process, making measurement more convenient and accurate.
Receiving system part: composed of speakers and indicator lights. The speaker emits a continuous buzzing sound and the indicator light flashes.
Usage:
When measuring, after allowing the winding reel to rotate freely, press the power button, place the measuring head into the water level tube, hold a steel ruler cable in hand, and slowly move the measuring head downwards. When the contact point of the measuring head contacts the water surface, the receiving system's speaker will emit a continuous buzzing sound. At this point, read the depth dimension of the steel ruler cable at the pipe mouth, which is the distance between the groundwater level and the pipe mouth.
Users must pay attention to two points when testing:
A) When the contact point of the measuring head contacts the water surface, the speaker will make a sound and the indicator light will flash. At this point, the steel ruler cable should be slowly released to carefully locate the exact position of the pronunciation or indication moment, and then read out the depth dimension of the point from the hole opening.
B) The accuracy of reading depends on timely judgment of the starting position of the buzzer or indicator. The accuracy of measurement is related to the operator's proficiency, so it should be practiced and operated repeatedly.
