A test method was developed to find the ideal optical material that supports the chemical reaction of some fuels. Optical plastics and resin were submerged for long periods of time in reservoirs of ethanol, gasoline, Diesel and biodiesel. The dimensional change and weight change of the submerged samples was measured. A special resin successfully supported the chemical attack of fuels. Samples of acrylic polymer and polycarbonate were used as type of optical plastic.
This study aims to build a prototype of a new device for measuring by optics, the level of liquids or liquefied gases in tanks without the use of moving parts for general applications, stationary or not, industrial and chemical vehicles. There are a lot of optical devices for measuring liquid level and various settings and runs, some devices with buildings and sophisticated technologies, complicated and more simple, but none of these devices has the configuration (provision and operation), for measuring by optical means, the level of liquids in tanks and reservoirs. That is a simple, efficient and cost effective device.
