Abstract

Upright Cylindrical Fixed Measuring Tank (TUTSIT) is commonly used to store liquids of high economic value. TUTSIT needs to be calibrated periodically. For TUTSIT inner diameter scanning, a prototype ultrasound-based (US) ranging distance scanner has been developed with 3 US transducers with a frequency of 42kHz. For TUTSIT diameter scanning, two US transducers are mounted in a mechanical system that rotates 360o automatically and continuously. To determine the altitude position during scanning, one US transducer is mounted vertically facing vertically down on a tripod supporting the scanner's mechanical system. The scanner system was tested on a 75 kL capacity TUTSIT on course II of the 4 courses in the tank. The scanned data, which came from cloud points from course II, were pre-processed to be cleaned of outliers. The test results show that the system has functioned properly to measure the inner diameter of the tank at a height of 227 cm, 253 cm, and 261 cm. The scanning measurement error at a height of 227 cm and 253 cm is ±0.5% while at a height of 261 cm, the measurement error is about ±2.3%. The flatness of the prototype position greatly affects the accuracy of the diameter measurement, as can be seen from the measurement error at a height of 227 cm and 253 cm which is better than the measurement at a height of 261 cm, which does not pay attention to the flatness of the prototype position.
