The non-invasive ultrasonic level sensor of SKE can be found at all corners over the world, at home and abroad, and they can reliably and firmly act as safety guards to accurately protect project sites at any angle, large or small!
The ultrasonic non-invasive level gauge of Shaanxi Shengke Electronic Technology Co., Ltd. is a high-tech level measuring instrument that integrates ultrasound, electronics and software.
It is a level sensor that can realize continuous measurement. It is easy to read, easy to install and maintain, and has a long service life.It can perform truly non-contact and accurate measurement of the liquid levels of various toxic substances, strong acids, strong alkalis and various pure liquids in high-temperature and high-pressure closed containers.
SKE (Shaanxi Shengke Electronic Technology Co., Ltd.) produces non-intrusive ultrasonic level transmitters, such as the SK-WY series, which are designed for measuring liquid levels, including oil, in various industrial applications.
These devices use sonar ranging principles, where an external probe is attached to the outside of a tank to collect ultrasonic signals. The system calculates the liquid level inside the tank without requiring direct contact with the medium, making it suitable for hazardous or corrosive substances like
oil.
In an oil level measuring application, the SKE non-intrusive level transmitter would typically be installed by attaching the ultrasonic probe to the tank’s outer wall, often at the bottom for level measurement. A secondary probe, known as the Diameter Calibration Sensor (CAL), might be placed on the sidewall to adjust for real-time variations in sound velocity due to temperature or environmental changes, ensuring accurate readings. The transmitter processes the reflected ultrasonic signals using specialized algorithms to determine the oil level and can output this data remotely via interfaces like 4-20mA, HART, RS-485, or Bluetooth.
This technology is particularly useful in oil-related industries—such as petroleum, petrochemical, or oil refining—because it eliminates the need for tank penetration, reducing risks of leaks, contamination, or downtime during installation. It’s marketed for applications involving flammable, volatile, or toxic liquids, which aligns with oil level monitoring in storage tanks or transport vessels. The system supports continuous, real-time tracking with a range of up to 30 meters and a measurement blind zone as low as 30mm, offering high accuracy (around 0.1%) and stability.
For a specific example, consider an oil storage tank in a refinery. The SKE non-intrusive transmitter could monitor crude oil levels without interrupting operations or requiring the tank to be emptied, providing data to a control center for process optimization or overflow prevention.
