1. System Overview
The company's groundwater online monitoring system is based on the company's own research and development
integrated groundwater level monitoring station, combined with the company's years of experience in the
automation of information technology in the water industry and the development of groundwater situation
control software, to constitute an online monitoring system for groundwater to meet various functional needs.
2. System structure
The national groundwater monitoring system consists of three major components: the groundwater level
monitoring station network, the VPN/APN data communication network, and the prefecture, province
(autonomous region) and national groundwater monitoring center.
3. Monitoring project
The main monitoring elements of the groundwater monitoring system are groundwater level, water temperature,
water quality and water output. Among them, groundwater level is the most common and important groundwater
monitoring element.
4. Monitoring equipment involved
In this program, we recommend the integrated ground water level monitoring station produced by our company. It is a qualified product for the detection of groundwater level monitoring equipment issued bythe “Quality Supervision and Testing Center for Hydrological Instruments and Geotechnical Instruments” of the Ministry of Water Resources.
5. Product Features:
* Using absolute pressure sensor, pneumatic electronic compensation, long service life;
* The sensor is made of all stainless steel with a built-in high voltage protection kit;
* Germany imported ceramic capacitor core, anti-overload capability up to 10 times the range;
* Integrated design, easy to install and reliable;
* Fully sealed design for long-term work in wet conditions;
* Support GPRS multi-centerand SMS to send data;
* Sending a change and resending, the message when the GPRS is faulty is automatically sent after the
GPRS is restored;
* Automatic data storage, historical data can be exported on site, or exported remotely.
