The digital ultrasonic level sensor is designed for precise level measurement with ultrasonic sensing technology. It features a 0.25–0.6m blind zone, 1mm resolution, and accuracy up to 0.25% F.S. under standard conditions. The integrated LCD provides clear readings of liquid level or distance, while the low power consumption design ensures efficient operation in industrial tanks, containers, and process systems.
Measurement Performance Advantages
- This digital ultrasonic level transmitter adopts non-contact ultrasonic measurement. The probe never touches liquid, avoiding blockage and contamination, greatly lowering
- maintenance frequency.
Equipped with an industrial intelligent chip and automatic temperature compensation technology, it delivers stable readings without fluctuation amid water level changes, dust, and water vapor. Long-term operation without repeated adjustment after installation. - The ultrasonic level meter features small blind zone and strong anti-interference capability to ensure reliable level detection under complex working conditions.
Structural & Application Advantages
- The ultrasonic level sensor features an integrated all-in-one design for quick installation and professional commissioning. Excellent waterproof and dustproof performance, suitable for indoor and outdoor environments.
- With no mechanical wearing parts, it is resistant to dirt adhesion and corrosion for longer service life. Compared with traditional level gauges such as float type, the transmitter avoids frequent clogging, regular maintenance, and easy failure caused by corrosion.
Applications
Capable of stable non-contact liquid level measurement under normal temperature and atmospheric pressure, the digital ultrasonic level transmitter can be applied to water level monitoring of rivers and reservoirs, liquid level measurement of sewage tanks, and detection of liquid media such as fruit juice and milk.

Q1: What is the blind zone of a digital ultrasonic level transmitter?
A1: The blind zone of a digital ultrasonic level transmitter is the minimum distance where the sensor cannot provide accurate level measurement. It is typically 0.25–0.6m, depending on the sensor model. Maintaining a proper distance between the sensor and liquid surface helps ensure reliable and accurate ultrasonic level measurement.
Q2: Does an ultrasonic level meter need to contact the liquid?
A2: No, a digital ultrasonic level meter does not need to contact the liquid. It measures liquid level by transmitting and receiving ultrasonic waves from above the surface. This non-contact design reduces corrosion and maintenance issues, making it suitable for water, wastewater, chemicals, and industrial process applications.
Q3: Can a digital ultrasonic level sensor measure wastewater?
A3: Yes, a digital ultrasonic level sensor is suitable for wastewater measurement. Its non-contact ultrasonic technology allows reliable level monitoring in sewage tanks, wastewater treatment systems, and industrial drainage applications without direct exposure to contaminated liquids. Proper installation helps ensure accurate and stable measurements.
Tips: Why does my ultrasonic level transmitter show incorrect readings?
A digital ultrasonic level transmitter may show incorrect readings due to improper installation, foam, turbulence, obstacles, incorrect settings, sensor contamination, or measurement conditions beyond its range. Checking the installation position, adjusting parameters, and ensuring a clear ultrasonic path can help restore accurate level measurement.
