Non-contact level sensors are the premium end of the spectrum of level measurement devices. They use more complicated measuring principles that don’t require contact with the measured product. This makes them more expensive but also more versatile.
The transmission of high powered acoustic waves ensures minimal losses through the environment where the sensor is located. Due to the high powered emitted pulse, any losses have far less effect than would be experienced by traditional ultrasonic devices. More energy is transmitted hence more energy is returned. Advanced receiver circuitry is designed to identify and monitor low-level return signals even when noise levels are high. The measured signal is temperature compensated to provide maximum accuracy to the outputs and display.
One highly effective way to measure liquid levels in non-contact applications is the use of ultrasonic liquid level sensors. Ultrasonic liquid level sensors are mounted at the top of a tank or vessel and use ultrasonic sound waves to calculate the depth of liquid. Agitated liquids can interfere with this process, but the use of still pipes can attenuate this when required. Ultrasonic level sensors are also capable of continuous level measurement in addition to point-level monitoring, another advantage over more traditional float switches.
