Level sensors in dams and reservoirs

Dams and reservoirs, as important water conservancy project hubs, take the burden of irrigation, power generation, drinking water for humans and livestock, flood prevention and control. The precise water level measuring of dams and reservoirs plays a key role in the safe operation of reservoirs, rational regulation of water resources, and prevention of floods and disasters. Recent years, as the development of science and technology, the water conservancy industry has put forward higher requirements for the automation, precision and real-time of water level monitoring. The focus is on promoting smart water conservancy and flood prevention and disaster reduction systems, providing broad space for the application of advanced monitoring equipment such as submersible level transmitters.

Pain Points of Dams and Reservoirs Level Measurement

1.Inefficient manual monitoring and large errors: Most of dams and reservoirs are located in remote outdoor areas. The manual sampling and monitoring model is time-consuming and labor-intensive, with slow data updates and large errors. The cost is also high, making it difficult to analyze the changes in groundwater in a timely and accurate manner.
2.Lack of real-time warning: Traditional systems lacks real-time monitoring and warning function. It is impossible to issue alarms in time when water levels are abnormal, and administrators cannot be notified in time when reservoir water levels approach or exceed the warning line, increasing the risk of floods.

3.High maintenance costs: Some level meter should frequently be maintained and calibrated, especially in the complex environment of reservoirs, maintenance work is complicated and costly.

Product Recommendation for Dams Water Level Measurement

GAMICOS GLT540 submersible level sensor is specially designed for reservoir and dams level monitoring. The sensor adopts a large water guide head design to prevent sediment from blocking the water inlet. It is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid, and is made of advanced isolated diffused silicon sensitive elements. The static pressure is converted into an electrical signal, after temperature compensation and linear correction, then is converted into a standard electrical signal (usually 4~20mA/0-5V/RS485) for output .

Characteristics of GLT540 level sensor：

1. High accuracy and stability: Original imported sensitive components are used, with good linearity and high temperature stability, to ensure long-term stable and accurate measurement in complex environments of deep wells.
2. Strong adaptability：The sensor is made of 316L stainless steel, which has good anti-corrosion properties and can adapt to both ordinary well water and corrosive liquid environments.
3. Easy to install：The submerged measurement method can be directly put into the reservoirs and dams to be measured without the need for complicated installation procedures.
4. Rich functions: Supports multiple signal outputs, such as 4 - 20mA, RS485, etc., which is convenient for connecting and communicating with various automation equipment or control systems to achieve remote transmission and centralized monitoring of data.

Customer Case Study

Customer Background

A medium-sized reservoir is responsible for irrigation and water supply in the surrounding areas. Previously, the water level was monitored by manual inspection combined with simple water level gauges. There were many challenges in daily data monitoring, such as untimely data acquisition and insufficient accuracy, making it difficult to accurately judge the timing of reservoir water storage and flood discharge. This posed a serious safety hazard, and a new monitoring solution was needed.

What Did They Encounter?

1.Manual inspection lag: Manual records are made twice a day, and the data blank period at night reaches 10 hours.
2.Insufficient equipment accuracy: Manual measurement accuracy is poor, high-precision recording is difficult to achieve, and data reliability is poor.
3.Poor intelligence: unable to achieve intelligent monitoring and management

How to Resolve?

According to customer needs, we provide a system combination of submersible level sensor GLT540+GPY119+GRT102. GLT540 provides high-precision data monitoring with an accuracy of 0.1%. The data is displayed on the control unit GPY119 and low, low-low, high, and high-high alarms are set. Finally, the data is transmitted to the cloud platform through a wireless module, which can realize remote data monitoring and alarm warning.

What can You Get?

1. More scientific decision-making: Accurate and real-time water level data allows reservoir management departments to formulate more scientific and reasonable dispatching plans based on weather forecasts, reservoir capacity curves and other data, optimize the allocation and utilization of water resources, improve the utilization efficiency of water resources, make irrigation water allocation more reasonable, and ensure the water demand of surrounding farmland.
2. Safety is guaranteed: The timely warning function effectively prevents the occurrence of flood disasters. By real-time monitoring of the reservoir water level, potential safety hazards such as embankment leakage can be discovered and dealt with in a timely manner. Since the use of the submersible pressure level sensor, the reservoir has not had any safety accidents caused by untimely water level monitoring.
3. Significant cost reduction: The frequency and workload of manual inspections are reduced, which reduces labor costs and avoids economic losses caused by unreasonable scheduling due to inaccurate data. The equipment is highly stable and maintenance costs are greatly reduced.
