What is a Ultrasonic measuring instrument?

An ultrasonic measuring instrument transmits ultrasonic waves (sound waves with a high frequency that cannot be heard by the human ear) to objects such as gases, liquids, and solids. A device that measures conditions. Sound waves have characteristics such as reflection, velocity, and attenuation. Characteristics such as reflection, speed, and attenuation of sound waves change depending on the material, concentration, flow rate, etc. of the medium (substance that mediates sound wave transmission). By measuring changes in the properties of this sound wave, the properties of the medium can be investigated.
