This article deals with the temperature error correction in ultrasonic level gauges using special sensor designs located in the lower part of the tanks. It is shown that there is a possibility of temperature error correction depending on temperature variation of the environment throughout the tank height. References 10, figures 3, table 1.
Key words: transient, discharge current, capacitor capacitance, rate of current rise.
