What is the difference between ultrasonic level meter and radar level meter?

What is the difference between ultrasonic level meter and radar level meter? Many people are puzzled by this, today I will explain the difference between the two.

Ultrasonic level meter mainly through ultrasonic waves to determine the height of the liquid medium position, and radar level meter through the radar judgment, which is the biggest difference between the two. The specific distinction is this:

Ultrasonic level meter in the work, the sensor sends out ultrasonic waves, ultrasonic waves through the liquid level surface will be reflected, and then be received by the sensor and converted into an electrical signal, the use of the launch, the reception of time according to the formula can be calculated from the distance, which belongs to the non-contact measurement, because the instrument will not touch the medium almost, so the ultrasonic level meter will not be affected by the measurement medium.

Radar level meter sends radar signals, because radar waves run at the speed of light, and the time of operation through the device can be converted into position signals, from which the liquid level height. This also belongs to the non-contact measurement, suitable for liquid, slurry, granular material and other media measurement.
