I. Overview
In order to achieve the rational utilization of water resources, it is important to apply new technological information and have real-time and accurate understanding and mastery of various water situation information. People can use this to make correct water resource scheduling and management, and prevent problems before they occur. For a long time, water level measurement has played a huge role in detecting potential accidents in a timely manner, preventing them before they happen. Water level is one of the important parameters for the safety of reservoir dams, water conservancy and irrigation scheduling, water storage, and flood discharge. At the same time, water level monitoring is required in many fields of industrial and agricultural production.
The TRM-2CX ultrasonic water level snow depth warning system is a digital water level measurement instrument that integrates many advanced technologies from both domestic and foreign sources. It has the characteristics of small size, low power consumption, high measurement accuracy, stable and reliable operation, simple operation, dual-use of AC and DC, and all-weather operation, filling the gap in the demand for unmanned and solar powered water level warning and monitoring products in winter in China.
Product composition: intelligent collector, protective chassis, sensors, communication system, monitoring software, bracket, power supply system, and signal cables, etc.
Scope of application: It is applicable to underwater section and underwater topographic survey of road traffic, Rivers and Lakes, ports and wharves, reservoirs and waterways, deep sea, navigation, underwater geophysical exploration, geological disasters and many other fields.

2、 Product Features

1. The sensor used in the system is a technically mature ultrasonic water level sensor, which emits an ultrasonic pulse and then receives the echo. By measuring the propagation time and air temperature, the distance can be calculated.
2. The sensor is equipped with a temperature sensor to correct the ultrasonic velocity. Easy installation, simply install the sensor a few meters above the monitoring water surface. Non contact measurement, long lifespan, suitable for measuring water levels within 10 meters.
3. This system can operate independently or be integrated into information systems in the application industry. Combining multiple TRM-2CX water level warning monitors can form a networked water level monitoring system, which can comprehensively grasp water level change data and provide a basis for decision-making.
4. When the water level measurement value exceeds the set warning value, the system will automatically alarm the control center. The alarm method adopts sound and light alarm, and one switch output control. The alarm parameters can be set manually on site or through microcomputer software.
5. Data management software: Running in Windows XP or above environment, real-time display of various data, automatic storage of detection data, data storage format in EXCEL standard format, connected to a printer to automatically print data, and can also be called by other software.
6. Large screen graphic LCD display with Chinese characters and graphic display functions, displaying multiple meteorological data channels on one screen for direct on-site observation.

7. The system adopts a high-performance microprocessor as the main control CPU and a large capacity data storage (storing more than 20000 pieces of data), which can continuously store data and the storage time can be set according to different requirements at different times.
8. The power supply can be AC 220V ± 10% 50Hz or DC: 12V, and the system can also be equipped with external solar panels for year-round outdoor use.
9. In order to meet the different needs of users, the system provides two communication methods: wired transmission and wireless transmission. The wired transmission method is to connect to the monitoring center PC through a standard RS232/RS485/USB communication interface. Wireless transmission methods can be divided into three types based on communication distance: short distance wireless transmission, medium distance wireless transmission, and long-distance wireless transmission.
10. The system host box is made of aluminum alloy material mold by die-casting, which has the functions of shock resistance, moisture resistance, anti magnetism, and anti strong magnetic interference. Can be used outdoors for a long time, with a streamlined appearance and easy installation. The overall design adopts industrial control standard design, portable structure, suitable for use in harsh weather environments.
