2. Product Overview:

The PT124B-226E settlement monitoring system's hydraulic static level gauge is a critical underlying monitoring sensor for engineering settlement systems; the static level measurement system is a precise instrument that measures the relative change in liquid surface height between two or more points. It is primarily used for monitoring vertical displacement and inclination in structures such as dams, nuclear power plants, wind farms, high-rise buildings, mines, landslides, and bridges. The static level system is typically installed on a measuring pier (base) or at the same level as the object being measured on the wall, usually with modular automatic measurement units to collect data, which is then connected to a computer via wired or wireless communication for automated observation.

3. Product Features:

【Wide Measurement Range】Up to 2500mm wide measurement range to meet the vast majority of monitoring requirements.

EASY INSTALLATION & TROUBLESHOOTINGThe electrical connection section uses high-pressure quick-liquid tubes/tube fittings and aviation connectors made of stainless steel, allowing for direct on-site installation without the need for a wrench.

【24/7 Online Monitoring】: Can be connected to various types of sensors via a data collector and integrated into the IoT monitoring cloud platform, forming automated monitoring solutions tailored to different needs.

High-Performance Computing ProcessingSelf-temperature compensation for stable operation over a wide temperature range; built-in filtering algorithm to eliminate background noise, ensuring more accurate data.

【IP68 Waterproof Design】The main body of the equipment is made of alloy aluminum, and the electrical part uses an alloy self-locking aviation waterproof plug to ensure convenient and reliable connections, avoiding potential risks of poor contact and water intrusion.

【High-Precision Data Measurement】: Utilizes high-precision digital sensors and a 24-bit MCU full digital circuit design, combined with temperature compensation data fusion algorithms, achieving measurement accuracy up to 0.02%, adequate for real-time automated measurement of structural displacements.

6. Application Fields:

Automated monitoring of uneven settlement for structures such as geological disasters, tunnels, buildings, ancient city walls, dams, rock masses, comprehensive utility tunnels, high-speed and metro rail lines, wind turbine towers, signal towers, roadbeds, cut-and-fill sections, and large storage tanks.

7. Usage Precautions:

The specifications for pipes and air tubes refer to the outer diameter of the pipes. You can simply select PU polyurethane tubes with the same outer diameter.

② Use regular pure water. However, in areas where freezing may occur during winter, antifreeze should be used according to the temperature, with options for -20℃ or -40℃ automotive radiator antifreeze.

The pipeline cut must be essentially straight and even; otherwise, there is a possibility of liquid leakage.

④In areas with significant temperature differences between day and night, thermal insulation measures should be employed. Insulating foam wrapped with piping for frost prevention can be used.

⑤ The range refers to the height from the hydrostatic level gauge to the liquid surface. The installation position of the sensor should be as close to the same horizontal plane as possible, slightly below the water tank's liquid surface.

⑥ The liquid level in the water tank should be above the height of all sensors.

⑦ To minimize bubble formation, a small amount of defoaming agent can be added.

Add a few drops of engine oil or silicone oil on the surface of the water tank to isolate the water from the air, which can significantly reduce water evaporation.
