FAQs
What makes ultrasonic level meters ideal for non contact liquid level measurement in water treatment tanks?
Ultrasonic level meters operate by transmitting high-frequency sound pulses toward the liquid surface inside a tank. When these pulses reflect back, the instrument calculates the distance and precisely determines the water level. This non-contact method eliminates physical interaction with the liquid, preventing contamination and removing the risk of sensor degradation from exposure to corrosive or contaminated water. Ultrasonic liquid level sensors excel in sedimentation tanks, aeration tanks, filtration systems, and disinfection units where media can be caustic, foamy, or otherwise inhospitable for direct-contact devices. The result is stable, low-maintenance monitoring—critical for each water treatment plant process stage, especially where access is limited or safety is a concern.
How does a guided wave radar level transmitter measure interface levels accurately in water treatment processes?
Guided wave radar level transmitters employ microwave pulses guided down a probe that extends into the tank. These pulses encounter material interfaces, such as between water and sludge or oil, and reflect differently based on the distinct dielectric constants of the layers. The transmitter analyzes the time interval between pulse emission and return to accurately calculate interface depth. Because this measurement relies purely on electromagnetic reflection, it remains unaffected by typical water treatment plant variables like temperature swings, pressure changes, vapor, or variations in water chemistry. As a result, guided wave radar technology ensures calibration-free, repeatable accuracy for challenging scenarios such as sludge blanket depth monitoring in sedimentation tanks.
Why is non contact level measurement preferred for sedimentation and aeration tanks?
Sedimentation tanks in water treatment often contain chemically aggressive, turbid, or sludge-laden water, while aeration tank function introduces turbulence and potential splashing.
