Measuring material levels in tanks and industrial environments is essential for controlling material quantity and preventing overflow or shortages. Level measurement methods include ultrasonic, radar, capacitive, and mechanical sensors, each offering distinct advantages.
Ultrasonic sensors use sound waves to measure the levels of liquids and solids. These sensors transmit waves and receive their reflections to calculate material levels. Radar sensors use electromagnetic waves to measure liquid and solid levels and are widely used in oil, gas, and chemical industries due to their high accuracy.
A newer technology in this field is capacitive sensors, which are used for measuring liquid levels in opaque tanks. These sensors detect changes in electrical capacitance and determine material levels. Additionally, mechanical sensors remain a cost-effective solution for certain applications.
