How to distinguish between radar level gauges and ultrasonic level gauges
Radar level gauges emit electromagnetic waves; materials with different dielectric constants affect the reflection of these waves, and they are not influenced by temperature or pressure； Ultrasonic waves are mechanical waves that propagate through a medium, and their properties are affected by temperature, pressure, and density.
One is a sound wave and the other is an electromagnetic wave; their prices also differ greatly. In terms of appearance, the bottom part of an ultrasonic device is usually a flat surface
