Key Features of Ultrasonic Externally Mounted Liquid Level Sensors [Dayu Electronics]
Ultrasonic externally mounted liquid level sensors are centered on non-contact measurement. They emit ultrasonic pulses and receive reflected echoes from the liquid surface, accurately calculating the liquid level height using the sound velocity formula. Their core features are reflected in three aspects:

Safety and Adaptability: The sensor is mounted externally on the container wall, requiring no openings or contact with the medium, completely eliminating risks of liquid corrosion, contamination, and leakage. It is especially suitable for highly toxic, flammable, explosive, strongly corrosive media, and high-pressure sealed containers such as LPG storage tanks and chemical reactors.

Ease of Installation and Maintenance: With a single-probe design, installation only requires close contact with the outer wall of the container, no shutdown or hot work is needed, and it supports online commissioning and infrared remote calibration, reducing maintenance costs by over 60%.

Accuracy and Stability: Built-in ASIC smart chip and temperature compensation algorithm eliminate environmental interference in real time, achieving measurement accuracy of ±2mm. With no mechanical moving parts and a service life of over 10 years, it delivers millimeter-level stable monitoring in industrial storage tanks, hydrological monitoring, and other fields.
