| Product Introduction |
The ultrasonic liquid level sensor utilizes the principle of ultrasonic echo ranging. The sensor is installed on the outside of the tank bottom, emits an ultrasonic signal from the bottom, which is reflected back upon encountering the oil surface. The liquid level height is then calculated based on the time and speed. |
| Simultaneously, combined with our company's proprietary digital signal processing technology, it overcomes interference from the container walls, thereby achieving high-precision non-contact measurement. |
| Probe Specifications: Diameter 33mm, Height 12.7mm, Cable Length 1m. The default measuring range is 1m, extendable up to 4m. |
| Application Scope: Already widely used in logistics fleets, passenger buses, oil tankers, fire trucks, various sanitation vehicles, and fuel tanks of different commercial vehicle types for real-time fuel level monitoring. |
