Built-in intelligent filtering algorithm eliminates interference from wind, water surface ripples and farm dust, ensuring stable and precise data output.
On-site HD Real-time Display
Comes with an integrated high-definition digital display screen, which intuitively shows real-time water level height and working status on site. Farmers and breeding managers can directly read accurate data at a glance without professional tools or supporting equipment, realizing convenient on-site inspection and quick status judgment.
Low Power Consumption & Wide Environmental Adaptability
Optimized low-power circuit design matches standard 5V safe voltage power supply, saving energy and supporting long-term uninterrupted operation. It adapts to complex outdoor farm environments, including high humidity, dust and variable temperature conditions, with strong environmental tolerance and ultra-low failure rate.
Plug-and-play & Easy Operation
Integrated modular structure with simple wiring and no complicated debugging. It supports rapid installation and use, requiring no professional technical operation. It is friendly for ordinary agricultural operators and fully suitable for popularized farm water level monitoring scenarios.
Working Principle
The UL-3L205 ultrasonic water level sensor works on the principle of ultrasonic echo ranging. The built-in ultrasonic probe emits high-frequency sound waves vertically downward to the water surface, and the sound waves are reflected back in the form of echoes after touching the liquid surface. The high-speed processing chip precisely calculates the time difference between signal transmission and reception. Combined with automatic temperature compensation technology, it corrects measurement errors caused by ambient temperature changes in outdoor farm environments, accurately converting the distance data into real-time water level height. The detected data is displayed on the local HD screen in real time, realizing continuous, automatic and reliable water level monitoring for agricultural and animal husbandry water storage equipment.

Application Fields
Tailored for the agriculture and animal husbandry industry, the UL-3L205 ultrasonic water level sensor is widely applicable to various farm water monitoring scenarios. It covers farm irrigation water tanks, reservoir water level detection, livestock and poultry drinking water storage tanks, aquaculture water pools, greenhouse water supply equipment and pastoral rainwater collection tanks. It realizes 24-hour automatic water level monitoring, effectively solving the problems of untimely water supply, water shortage overflow and waste of water resources in agricultural planting and animal breeding. With affordable pricing and stable performance, it is ideal for large-scale popularization and intelligent upgrading of water management in modern agriculture and animal husbandry.
Installation Method
This ultrasonic water level sensor adopts simple and efficient top vertical non-destructive installation, suitable for various agricultural water tanks and pools. First, select a flat and unobstructed position at the top of the water storage equipment, ensuring no obstacles such as branches, pipelines and floating objects directly below the installation point to avoid blocking ultrasonic signals. Fix the sensor vertically with the probe facing straight down and parallel to the horizontal water surface. Complete standard 5V power wiring and power on the device, then wait for automatic self-check and initialization. After stable operation, real-time water level data will be displayed on the local screen. The whole installation process requires no drilling, no damage to equipment, no professional tools, saving installation time and labor costs for farm use.
