Advantages and disadvantages of ultrasonic level measurement

There are some advantages of ultrasonic level measurement which are given below,

• The ultrasonic level measurement is suitable for measurement in liquid and solid.
• It is simple in construction and design.
• It does not require contact with processed material.
• It provides continuous level measurement.
• It has high accuracy.
• The sensitivity is high.

There are some disadvantages of ultrasonic level measurement which are given below,

• The ultrasonic level measurement is comparatively expensive.
• If heavy foam is present on the surface it acts as an absorbent which creates errors.
• Targets of low density, like foam and cloth, tend to absorb sound energy; these materials may be difficult to sense at long range.
