Standard Ultrasonic Level Meter
Page Features
Non-contact, high precision
Wide range of measurement conditions, suitable for most applications
Ideal for open-air liquid level measurement
Adjustable measuring range: 0-15 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 with the medium and ease of installation/maintenance have led to increasing application in industrial settings. They are widely used for measuring the height of various liquids and solid materials, offering irreplaceable advantages in applications with high sanitary requirements.
Performance Features
Non-contact measurement, unaffected by material characteristics. Easy installation, simple maintenance, strong anti-interference capability. Local display with optional analog, switching, and RS485 outputs for convenient interfacing with related equipment.
Dynamic echo processing technology enables adaptation to various complex working conditions.
False echo learning function allows the meter to correctly identify the true echo and achieve accurate measurements even in the presence of multiple false echoes. The transducer incorporates a temperature sensor for automatic temperature compensation of measurements.
Acoustic matching technology ensures more efficient radiation of the emitted ultrasonic power, enhancing signal strength for precise measurement.
