The ultrasonic level gauge is composed of an ultrasonic transducer(probe) emits high-frequency pulse sound waves, which are reflected back to the surface of the measured object (material), and the reflected echo is received by the transducer and converted into an electrical signal. The propagation time of the sound waves is proportional to the distance from the sound wave to the surface of the object. The time between the sound wave and the return sound wave is detected to calculate the distance from the sensor to the surface of the material, thereby calculating the height of the level.
★Non-contact media measurement, is not affected by the viscosity, specific gravity, etc.of the measured medium, and has strong anti-interference;
★Use environmentally friendly materials and do not pollute the measured medium;
★Non-toxic, can be used for pharmaceutical and food industry measurement;
★It can be equipped with relay contact output to realize the level alarm function;
★Panel button setting parameters, user parameter setting is convenient and fast;
★Using microprocessor and unique echo processing technology, it can adapt to the level and liquid level measurement under various complicated working conditions;
★With self-learning function, it can identify the true echo, and the measurement result is accurate. It has automatic temperature compensation, suppressing drift and improving measurement accuracy.
★The protection grade is IP67, which can be used in most outdoor working conditions.
