Level transmitters play a vital role across diverse industries, including oil and gas, chemicals, and food and beverage, by measuring liquid, slurry, lump, and powder levels in tanks and vessels. Ultrasonic and radar level transmitters are popular choices, both operating on the Time of Flight principle. Ultrasonic transmitters employ high-frequency sound waves, while radar transmitters use microwave radar signals. They emit waves reflected back by the material's surface, and by calculating the time of flight, determine substance levels. Ultrasonic is cost-effective but sensitive to environmental factors, while radar excels in challenging conditions. Choosing the right technology depends on material, environment, cost, and maintenance considerations.
