Practical Ultrasonic Level Meter
Page Features:
High accuracy, long lifespan
Product includes display
Suitable for open-air liquid level measurement
Adjustable range 0-10 meters
Product Overview:
Ultrasonic level meters calculate distance by measuring the time required for transmitted ultrasonic waves to reflect off a material or liquid surface. Their non-contact nature and ease of installation/maintenance make them increasingly popular in industrial applications. They are widely used for measuring the height of various liquids and solid materials, offering irreplaceable advantages, especially in hygienically demanding sites.
Performance Characteristics:
■ Non-contact measurement, unaffected by material properties. Easy installation and maintenance, strong anti-interference capability. Local display. Options for analog, switch, and RS485 output for convenient interfacing with related equipment.
■ Utilizing dynamic echo processing technology, the ultrasonic level meter adapts to various complex working conditions.
■ Features false echo learning function, enabling the instrument to correctly identify the true echo and achieve accurate measurement results even in the presence of multiple false echoes. The transducer has a built-in temperature sensor for automatic temperature compensation of measurements.
■ Employs acoustic matching technology, allowing the transducer’s emitted power to radiate more efficiently, enhancing signal strength for accurate measurement.
