Non-Contacting Level | <p>Non Contact Level Sensors for Liquids can be broken down into two sensing technologies, <strong>Radar and Ultrasonic</strong>. Radar non contact level sensors work by sending out short microwave signals toward the liquid via the sensor. The microwave signal then hits the liquid surface and bounces back toward the sensor.</p><p>Non-contact level measurement with radar is <strong>characterized by a particularly high measurement accuracy</strong>. The measurement is affected neither by fluctuating product properties nor by changing process conditions such as temperature, pressure or intense dust generation.</p>
