What Is an Ultrasonic Level Transmitter?
An ultrasonic level transmitter is a device that uses ultrasonic pulses to measure the level of a substance in a container. Positioned at the top of the container, it gauges the fill level by calculating the time it takes for the ultrasonic pulse to travel to the substance and back.
This type of transmitter, operating on ultrasonic waves, is a cost-effective option among non-contact measurement tools. Capable of measuring levels ranging from a few centimeters to several meters, it is particularly effective for transparent substances like water. However, its performance can be affected by temperature and humidity fluctuations, and it may have reduced accuracy in the presence of slurry, foam, dust, or vapor. Ultrasonic level transmitters are ineffective in a vacuum and are predominantly used for fluid level measurements due to their precision in point-specific measurements.
