Water Level Monitoring in a 600-Meter Deep Well at College of Earth Sciences,Jilin University

Case Description

Specific Requirements

Requirements: There are two deep wells on site, one 500 meters deep and the other 600 meters deep. Real-time monitoring of the liquid level in the deep wells is required, and a 30-meter low-level alarm to stop the pump is set to prevent the deep well pump from running dry and burning out, thus protecting the deep well pump while monitoring the liquid level in real time.

Requirements Analysis

Due to the special nature of deep well liquid level measurement, non-contact methods such as ultrasonic waves cannot effectively transmit signals, and magnetic float and bubble type cannot be used for such a deep range. Therefore, only the WH311 submersible deep well liquid level probe can be selected. It uses laser hydrostatic pressure principle, built-in strong anti-high pressure and high-seal sensor chip, and all-welded integral structure to ensure the sealing performance under 1000 meters of water (withstanding 100Bar underwater pressure). The signal transmission uses high-strength polyurethane steel wire cable (during laying, attention must be paid to the protection of the cable) to ensure real-time, high-precision and stable output of the measured signal.
