A preliminary prototype design of underwater data acquisition tool

Abstract

In this research, a preliminary prototype of underwater data acquisition tool was studied. Commercially available instruments that measure water temperature and other parameters usually needed large amount of data which lead to inflexible experiments and expensive. The objective of this research has lead to the development of three preliminary designs, in which the characteristics of the prototype were determined. All the designs were virtually drawn into autographic drawing in AutoCAD and 3D drawing in SolidWorks. The characteristics of the best and suitable design were determined using pairwise comparison chart (PCC) method and morphological chart method. The actual prototype was built after the best and suitable design was determined. In order to determine the efficiency of underwater storage measurement, the prototype tested in two conditions: the inlet does not have a nonreturn valve installed and the inlet has a non-return valve installed. Finally, development of data acquisition tool had done to fulfill its task to record seawater temperature. This research can prove that the prototype and design is highly efficient for underwater storage measurement in preliminary which can lead to development of new instruments for underwater data acquisition tool in future.
