Introduction to Self-contained Water Level Gauge

The self-contained water level gauge is a water level recording device based on the principle of pressure measurement.

I. Working Principle
The working principle of the self-contained water level gauge is to measure the water level height using changes in air pressure signals within the pipeline. When the measuring tube is immersed in water, the pressure of the water acts on the sensor, and the water level height is calculated by measuring the change in pressure. Meanwhile, the temperature sensor in the device compensates for temperature effects in pressure measurements to ensure data accuracy.

II. Composition and Structure
The self-contained water level gauge typically consists of a measuring tube, pressure sensor, temperature sensor, and built-in battery. The measuring tube houses the pressure sensor, which senses changes in water pressure; the temperature sensor monitors ambient temperature to correct pressure measurements; and the built-in battery provides power support, enabling the device to operate for extended periods without an external power source.

III. Characteristics
High Accuracy: The self-contained water level gauge employs high-precision sensors and advanced measurement techniques to accurately record changes in water level.
Low Power Consumption: The device is designed for low power consumption, allowing a single battery to operate continuously for several years, reducing maintenance costs.
Easy Installation: The self-contained water level gauge is compact and convenient to use, enabling easy installation on various objects such as seabeds, piers, and docks.
Long Lifespan: The internal components of the device are made of corrosion-resistant materials, capable of adapting to harsh marine environments and extending its service life.

IV. Application Areas
The self-contained water level gauge is widely used for long-term water level and tidal observations in oceans, rivers, lakes, and other water bodies. In fields such as hydraulic engineering, environmental monitoring, and hydrology research, the self-contained water level gauge accurately records changes in water level and stores the data internally for subsequent analysis and processing.

V. Precautions for Use
When installing the self-contained water level gauge, ensure that the sensor probe is securely installed below the lowest low tide level and determine the elevation of the sensor probe's zero point.
When reading data, retrieve the self-contained water level gauge from the measurement point and read the records through the data interface.
Regularly maintain and calibrate the device to ensure its measurement accuracy and stability.
In summary, the self-contained water level gauge is a high-precision, low-power, easy-to-install, and long-lasting water level recording device that plays an important role in water level observations across various fields.
