Product Overview

The ADDA-LE-64 ultrasonic level meter is a digital level instrument controlled by a microprocessor. During measurement, ultrasonic pulses are emitted by the sensor and reflected by the liquid surface, then converted into electrical signals to calculate the distance to the measured surface.

Because the measurement is non-contact, the product details state that the measured medium is almost unrestricted and that the instrument can be used for height measurement of various liquids and solid materials.

Working Principle

The ultrasonic level meter emits ultrasonic pulses from the transducer. When the pulses reach the surface of the measured medium, part of the reflected echo is received by the same transducer and converted into an electrical signal.

The ultrasonic pulse travels at the speed of sound. The time interval between emission and reception is proportional to the distance from the transducer to the measured surface. The product details express the relationship as S = C x T / 2.

Key Features

• Non-contact ultrasonic measurement.
• Echo Discovery processing for complex operating conditions.
• False echo learning function for identifying the real echo under multiple false echoes.
• Built-in temperature sensor in the transducer for temperature compensation.
• Acoustic matching technology for improved signal strength according to the product details.
