Oil tank level is an important control parameter in oil depot management. According to the principle that liquid can absorb guided wave propagation energy wall, this paper studied a non-reference detection method of external ultrasonic switch based on signal change value between current and previously signal. The experimental results show with center frequency 30 kHz sensitive low misjudgment d...

This paper presents an experimental study on a single tank thermal energy storage (TES) system integrated with cooking unit. The had capacity of 45 L oil. chamber was embedded in the tank, thereby eliminating use pumps and connecting pipes between unit designed to make good physical contact, circumferential basally, pot, improve rate heat transfer. Experimental tests were performed oil only oil...

This paper presents a numerical calculation method that allows for the simulation of mechanical and acoustic behaviour transformer tank. In order to simulate vibroacoustic an oil-immersed power transformer, acoustic-mechanical coupled three-dimensional finite-element model was setup. The is performed in frequency domain at frequencies adjacent driving frequency. A vibration source closely resem...

Tanks, as instruments in oil and its product’s amount measurement system chain, must be regularly maintained metrologically inspected, they significantly contribute to uncertainty. However, when measuring a change the of stored material (i.e., transfer), uncertainty becomes highly dependent not only on mass transaction but also initial liquid level tank. This paper provides modeling uncertainti...

cylindrical steel tanks are important components of many industrial plants such as oil refineries and chemical plants. usually failure of cylindrical tanks leads to serious consequences. during the past earthquakes such as 1964 alaska and 1999 turkey seismic performance of cylindrical tanks revealed that tanks are seismically vulnerable. therefore, evaluation of seismic performance of these str...

Oil theft always results in huge economic loss, human casualties, and extremely environmental pollution especially when the leaks from crude oil pipeline are not detected and repaired timely. In this paper, we focus on how to detect and monitor abnormal noise and vibration beforehand or in real time by the Internet of Things (IoT). Firstly, the diversities of crude oil theft and the difficultie...
