Ultrasonic level measurement technique can not be suitably applied in all fields since use of ultrasonic level sensors includes few setbacks too. Many factors exist which have the tendency to influence the returned echo signal back to the sensor. Some of them include:
- Materials like powders etc.
- Heavy vapors
- Surface turmoil
- Foam
- Ambient noise and temperature
Besides, ultrasonic level measurement devices do not work satisfactorily in areas involving vacuum or high pressure conditions.
