Swimming pools, as common leisure and sports facilities, are widely exist in residential area, fitness club, hotels, resorts, and public sports venues. Design and construction of the swimming pools should take various respects of factors into consideration to ensure the users’ safety, comfort and water quality hygiene. The swimming pools can be roughly divided into two categories, they are indoor swimming pools and outdoor swimming pools. According to the use and design of the swimming pools, they are competition pools, training pools, recreational swimming pools (children’s padding pools), Spa pools, etc. They have their own standards and requirements in terms of sizes, depth and water temperature control. Therefore, in order to solve the key problems of water level control in swimming pool maintenance, and ensure the safe, efficient and resource-saving operation of the swimming pool, it is necessary to accurately monitor the water level, water temperature and other parameters of the swimming pool according to different requirements.
1.Security monitoring: It is extremely important to maintain suitable water level for pool users. Too high may cause overflow and increase the risk of drowning, while too low may affect the normal operation of pumps and other equipment, or even damage them.
2.Water quality assurance:Stable liquid level helps to maintain the system balance and ensure the even distribution of the disinfectants and chemical additives.
3.Intelligent management: With the popularization of the Internet of Things, the modern swimming pools liquid level measurement system tend to highly automated and intelligent.
For swimming pool level monitoring applications, We adopt GLT500T temperature-liquid integrated level sensor to monitor water level and temperature of the swimming pools. The submersible level transmitter measures the liquid level by directly putting the sensors into water. It works based on the principle of static pressure. The static pressure of the water is proportional to the water depth. The greater the water pressure felt by the sensor probe, the higher the liquid level. The present liquid level can be exactly known through built-in sensor conversion. Built-in PT100 sensor measures water temperature, which can be directly connected with automatic control system. Accurate liquid level measurement system can adjust water level in time and avoid potential safety hazards.
For disinfection applications in swimming pools, we adopt anti-corrosion level sensor GLT570 anti-corrosion level sensor to monitor liquid level in disinfection storage tanks, and for staff to replenish disinfectant water in time, and disinfect water in swimming pools regularly and quantitatively. With wireless module, remote monitoring of water level information can be achieved.
1.Accuracy:Modern submersible level sensor has the characteristics of high accuracy, can reflect liquid level changes accurately in real time.
2.Durability: The product is designed with corrosion-resistant housing, suitable for water with chemicals in swimming pools.
3.Easy to maintain: Due to its simple structure, it is usually only necessary to clean the probe regularly to maintain measurement accuracy.
Flexibility: It is suitable for swimming pools of different sizes and shapes, with flexible installation positions and will not affect the beauty of the swimming pool.
An Australian swimming pool renovation project contractor undertook a swimming pool intelligent transformation project for a resort hotel. The hotel has a large outdoor pool and several small hot spring pools, which faces the challenges of complex water level management and high labor costs. Especially during seasonal changes and special weather conditions, manual monitoring and adjustment of water levels is time-consuming and prone to omissions.
We recommended customers to use submersible level transmitter to monitor level of the swimming pools. High sensitivity GLT500 submersible water level sensors are installed on each pool, and are connected to the central control system through anti-corrosive cables. Equip with the display control instrument GPY119, set the high and low limit of the liquid level, output the relay switch signal, and control the action of the water inlet pump and drainage pump. When the water level is lower than the lower limit, the water inlet pump will be activated to replenish water to the swimming pool. When the water level of the outdoor swimming pool exceeds the alarm upper limit due to sudden rainfall, the drainage pump will be activated to avoid accidents. The liquid level data can be directly uploaded to the cloud through the wireless module GRT102 to achieve remote monitoring of the liquid level.
1.Automatic adjustment: After setting the safe water level range, when the water level deviates from the preset value, the system will automatically trigger the water replenishment or drainage mechanism without human intervention, ensuring that the swimming pool maintains the ideal water level around the clock.
2.Cost savings: Through precise control, the waste of water resource is greatly reduced, and the energy loss caused by improper manual operation is reduced.
3.Improved safety: The high water level warning function integrated in the system can promptly initiate emergency drainage in heavy rain weather to prevent overflow, thus ensuring the safety of tourists and the integrity of surrounding facilities.
4.Convenient management: Hotel managers can check the water level status of each pool at any time through the mobile phone APP and receive alarm notifications, realizing remote monitoring and improving management efficiency.
