Nexisense Water Management Cases: Application of Pressure and Level Sensors
Background of the Water Management Industry
Water is the source of life and an essential natural resource for socio-economic development. With global environmental degradation, freshwater resources are increasingly scarce, and the water management industry faces unprecedented challenges. Through wastewater treatment, water reuse, and desalination, enterprises and governments can improve water utilization efficiency and mitigate water scarcity.
In the water treatment industry, precise control of parameters such as temperature, pressure, flow, and level is crucial. Modern water management systems widely integrate temperature sensors, pressure sensors, flow sensors, and level sensors to enable full-process monitoring and automated management. With increasing environmental requirements and technological advancements, the industry demands higher accuracy, reliability, and durability from sensors and transmitters.
Application of Sensors in Wastewater Treatment
The water supply and wastewater treatment sectors increasingly rely on pressure transmitters to ensure system stability and reliability. Pressure transmitters provide precise measurements under extreme conditions, including high temperatures, mechanical shocks, and vibrations, supporting system protection and quality control.
Automatic level control is also critical. For example, if a reservoir is outdoors while treatment equipment is indoors, sensors and their cables may become damp, causing control errors. In continuous wastewater treatment equipment, low-level protection is essential to prevent pump dry running or damage to electrolytic treatment equipment due to insufficient water.
Modern transmitters offer low response times (as low as 1 ms), minimal zero drift, and over 100 million operational cycles, making them widely applicable in the water treatment industry. Additionally, in desalination plants or corrosive media such as sludge, high-performance pressure sensors can still operate stably, with excellent vibration resistance, suitable for installation near pumps and critical water treatment equipment.
Application of Sensors in Hydropower Plants
The level of automation is a key indicator of modern hydropower plants. Computerized monitoring systems act as the "brain" of the automated system, while sensors serve as its "eyes and ears," collecting real-time pressure, flow, and level data from turbines and auxiliary equipment.
Nexisense provides a range of stable, high-quality sensors and transmitters applicable to hydraulic turbines, pumping stations, water supply networks, and auxiliary systems, enabling:
Real-time monitoring of turbine pressure, level, and flow
Accurate data to support automated control
Auxiliary system protection, enhancing safety and operational efficiency
Reduced maintenance costs and equipment downtime risks
