Its working principle is to measure water pressure, calculate the water level. This product is characterized by no need to build static water logging, the sensor can be fixed at the river bottom, With the pressure tube to eliminate atmospheric pressure, which measured the water level. There are two types of pressure gauges.
It uses solid-state piezoresistive devices for sensors, can be directly into the water pressure or voltage modulus of the amount of output frequency,
with wire transmission to the shore for processing and recording.
Equipped with a special 4G cloud storage capabilities, easy data view, transfer to the system in the cloud platform, the data will be automatically stored as historical data.
It not only can quickly view the current data of each sensor, but also can export data in the form of EXCLE table file for further data analysis and processing by other software.

The infiltration line refers to the intersection of the free water surface formed by the infiltration of the water from the dam face to the downstream surface, and the cross section of the dam body.
By understanding the location and change of the dam's infiltration line, it is possible to determine whether the dam is stable to ensure safe operation and verify the design.
Water level monitoring station using input pressure water level sensor, When the sensor is fixed at a certain point under the water, the water pressure above the measuring point height plus the point of elevation, you can indirectly measure the water level.
It is a digital, high precision, high reliability, low power, easy to use, can achieve long unattended, with automatic memory function of the hydrological monitoring instruments.
① Communication lines and water level line interface is never placed in the water, to be placed in the junction box.
② Wire can only be transmitted signals, can not be forced.
③ Water level probe to avoid the entry of debris, be sure to place more than 500px from the bottom of the place，recommended to use water-permeable items wrapped（such as gauze and so on）.
