Product Features
Dual Solar & Battery Power Supply, Ultra-Low Power Consumption
The US-3W202 sensor adopts an optimized low-power chip solution, supporting solar self-charging and built-in battery backup power supply. It can work continuously for a long time relying on natural light, eliminating frequent battery replacement and manual power maintenance, greatly reducing later operation and maintenance costs, and adapting to outdoor unattended working environments.
Tuya APP Intelligent Remote Monitoring
Compatible with the mainstream Tuya smart system, the sensor supports wireless data transmission. Users can remotely monitor real-time liquid level data, view data change curves, set high and low liquid level alarm thresholds, and receive mobile phone push alarms through the Tuya APP. It realizes intelligent, visualized and automated tank level management, no need for on-site manual inspection.
Non-Contact High-Precision Measurement
Utilizing ultrasonic non-contact detection technology, the sensor does not need to be in contact with the measured liquid medium, completely avoiding measurement failures or equipment damage caused by medium corrosion, scaling, blockage and liquid turbulence. It features stable measurement data and strong anti-interference ability, which can adapt to complex on-site working conditions.
Compact Integrated Design & Easy Deployment
The whole machine adopts an integrated compact structure with small size, light weight and good waterproof and dustproof performance. It has no complicated wiring and debugging procedures, supports rapid on-site installation and fixation, and is compatible with most standard water tanks, storage tanks and water storage facilities in water conservancy and municipal scenarios, with strong scene compatibility.
Working Principle
The US-3W202 ultrasonic tank sensor operates based on the ultrasonic echo ranging principle. The sensor probe actively emits high-frequency ultrasonic pulses outward, and the ultrasonic waves propagate through the air medium. When the waves touch the surface of the liquid in the tank, they will be reflected back to the sensor probe to form echo signals. The built-in high-precision processing chip accurately records the time difference between ultrasonic emission and echo reception. Combined with the real-time ambient temperature compensation algorithm, it calculates the vertical distance from the sensor to the liquid surface, and then converts the distance data into accurate liquid level height values. Finally, the processed level data is wirelessly transmitted to the Tuya APP terminal to realize real-time monitoring, data recording and over-limit alarm functions. The whole measurement process is non-contact, safe and stable, and is not easily affected by liquid density, color and other factors.

Application Fields
This ultrasonic tank sensor is professionally oriented to water conservancy and municipal engineering scenarios, and is widely applicable to various liquid level monitoring scenarios in the industry. It covers municipal domestic water storage tank monitoring, rainwater collection tank level detection, water conservancy reservoir auxiliary level monitoring, pipeline buffer tank liquid level management, municipal sewage tank level early warning, and rural water supply tank intelligent monitoring. It can realize 24-hour automatic real-time monitoring of liquid levels for water conservancy infrastructure and municipal supporting facilities, helping engineering departments realize refined and intelligent water resource management, effectively prevent water overflow, water shortage and equipment idling problems, and improve the overall operation efficiency of water conservancy and municipal projects.
Installation Method
The US-3W202 ultrasonic tank sensor adopts top suspended fixed installation, which is simple, fast and firm with no complicated wiring. First, select a flat and unobstructed position in the center of the top of the monitored tank to ensure no shelter above the liquid level detection area, so as to avoid blocking ultrasonic propagation and affecting measurement accuracy. Second, fix the sensor on the top of the tank through the matching fixed bracket, keep the probe vertically downward and parallel to the liquid level, and ensure the probe is 0.1m above the maximum liquid level to avoid submergence. Finally, complete the simple power-on pairing with the Tuya APP. After successful network configuration, the sensor can start real-time level monitoring. The whole installation process does not require cutting the tank body or contacting the internal medium, with zero damage to the equipment and short construction cycle.
