Built-in intelligent signal filtering algorithm, which can effectively filter interference such as water surface fluctuations and tiny air currents, ensuring stable and consistent detection data without frequent data jumping.
Working Principle
The UL-3L204 ultrasonic water tank level meter operates based on the ultrasonic echo ranging principle. The ultrasonic probe emits high-frequency ultrasonic pulses vertically downward to the water surface of the tank. After the ultrasonic waves touch the liquid surface, they are reflected back to the sensor probe in the form of echoes. The internal high-speed processing chip accurately records the time difference between ultrasonic signal transmission and reception. Combined with the built-in temperature compensation algorithm, it corrects the influence of ambient temperature on ultrasonic propagation speed, and automatically calculates the real-time vertical distance from the sensor to the water surface, so as to obtain the accurate water tank level height. The measured data is synchronously displayed on the local display screen and uploaded to the Tuya APP in real time to realize intelligent monitoring and automatic alarm functions.

Application Fields
This UL-3L204 ultrasonic water tank level meter is professionally tailored for industrial and storage scenarios, widely applicable to industrial manufacturing and warehousing fields. It covers industrial production water supply tanks, circulating water tanks, fire reserve water tanks in factories, warehousing storage water facilities, and supporting water tank monitoring for industrial supporting equipment. It can realize 24-hour uninterrupted intelligent level monitoring for industrial production and warehousing storage systems, effectively solve the problems of inaccurate manual detection, delayed abnormal discovery and high management cost, and help enterprises realize refined and intelligent water resource management.
Installation Method
This product adopts top non-destructive installation, which is simple, fast and safe without drilling or damaging the water tank. First, select a flat and unobstructed position in the center of the water tank top to ensure no obstacles such as pipelines and brackets directly below the installation position, so as to avoid blocking ultrasonic signal transmission and affecting measurement accuracy. Fix the sensor vertically on the reserved installation hole or fixed bracket at the top of the water tank to keep the probe downward and parallel to the horizontal water surface. Complete the 5V power supply wiring, turn on the equipment power, and wait for the device to self-check and initialize. Finally, complete network configuration through Tuya APP, and it can realize real-time level monitoring and remote alarm functions. The whole installation process requires no professional tools and complex debugging, saving installation time and labor cost.
