    Overview

    SUCH ultrasonic level sensor enables non-contact measurement of various media, including liquids (water, fuel, oil), solids (metal, non-metal), and powders (chemical materials). It offers measuring ranges of 0-5m, 0-10m, 0-15m, 0-20m, and up to 0-60m. Equipped with an LCD display and an ultrasonic probe, this ultrasonic level transmitter ensures reliable performance for a wide range of industrial and outdoor applications.

    Feature

    • Streamlined Transparent Top Cover: The non contact ultrasonic level sensor features a side-thickened top cover design that leverages light refraction to reduce sunlight exposure. (Note: a sunshade is still recommended on the sun-facing side during installation.)
    • Comprehensive Protection Design: The slanted electrical interface prevents vapor and dust ingress, protecting internal components and achieving true IP65 protection.
    • Fully Enclosed Cast Probe: The integrated probe ensures IP68 protection, preventing moisture ingress and guaranteeing long-term sensor reliability.
    • Custom PTFE Probe Option: The ultrasonic level transmitter can be equipped with a PTFE probe, offering excellent corrosion resistance, self-lubrication, and non-stick properties—ideal for corrosive or condensation-prone environments.

    Algorithm a. Algorithm of variable frequency
    Three adjustable emission frequency (low, medium and high) can meet the level measurements of different situations, such as sewage liquid level, acid and alkali liquid level, material level, etc. It can reduce the interference caused by the bubbles when mixing.
    b. Filtering algorithm (remove false echoes)
    The liquid level intelligent algorithm design effectively eliminates false echoes in actual measurement, improves signal-to-noise ratio, and guarantees actual liquid level measuring accuracy.
    Function Real-time monitoring and display 4 parameters: level (m), distance (m), current (mA) and temperature (℃).

    FAQ
    ❯

    A non-contact ultrasonic level sensor measures the liquid level by utilizing the time difference between the emission and echo of ultrasonic waves. The sensor does not require direct contact with the medium and is suitable for measuring the level of liquids, slurries, or solid particles.

    ❯

    The ultrasonic level sensor emits ultrasonic pulses towards the target surface. The sound waves are reflected back from the liquid or material surface. The sensor calculates the round-trip time of the sound wave and, combined with the speed of sound, obtains the height of the medium, thus calculating the liquid level or distance.

    ❯

    Yes, ultrasonic level sensors can be used in corrosive liquids, strong acids, or strong alkalis because they are non-contact devices and do not directly contact the liquid. However, the sensor's housing and protective materials (e.g., PTFE, PVDF, or stainless steel) must be corrosion-resistant to ensure long-term durability and measurement accuracy.
