جبران‌سازی تغییرات دما در دستگاه سنجش حجم با استفاده از الگوریتم بهینه سازی

The acoustic volume-meter device is sensitive to the variation of temperature. this temperature sensitivity is found to be originated from the mechanical part of the device. to deal with the negative effects of temperature variations temperature compensation is a cost effective method. a temperature sensor is included in the mechanical part and is connected to the interface board and the data from microphones and this sensor is recorded simultaneously. based on the collected data and the particle swarm optimization algorithm, a function is derived that compensates the effect of temperature. the results indicate that the using the presented method, the inaccuracies due to the temperature variations can be significantly reduced and a conduct more accurate measurement.
