Working Principle:

1. Emission of Sound Pulse: The ultrasonic sensor emits a pulse of sound waves toward the surface of the material.
2. Reflection of Sound Pulse: The sound pulse reflects off the surface of the material and returns to the sensor.
3. Time Measurement: The sensor measures the time it took for the pulse to travel to the surface and back.
4. Distance Calculation: Based on the time it took for the pulse to return, the distance to the material’s surface is calculated. This distance is then used to determine the level of the material.

Applications:

• Water and Wastewater Treatment: For measuring the level of water or sludge in tanks, ponds, or reservoirs.
• Chemical and Oil Industries: For monitoring liquid levels in storage tanks or pipelines.
• Food and Beverage: In silos or storage tanks for ingredients or products.
• Mining and Agriculture: For measuring levels of bulk solids, grains, and other granular materials.

Advantages:

• No moving parts, reducing wear and tear.
• Suitable for a wide range of environmental conditions.
• Can be used in both open and closed vessels.
• Provides continuous level measurement.
• Can be integrated into automated control systems.
