The segments of the sugar and alcohol markets, mines and energy, oil and gas, maritime transport, paper and pulp, food, chemical and petrochemical, and others, have the need to measure and control various process variables, among them measurement level, which represents up to 15% of these variables, and most applications require their control in aggressive environments such as corrosive liquid media, abrasives, high and low temperatures, liquids with suspended solids, fouling, etc. In this plot, around 2% finds some kind of measurement difficulty. Seeking to meet market requirements, which seeks innovative solutions with competitive costs and performance, AtriaTec will develop a Level Transmitter to measure liquid levels at points where environments have some kind of arduity. Through this solution, the measurements are made with better performance and lower cost compared to other available technologies. The development of the design and the constructive way were results of experiences of field problems and user requests. Bubble level measurement technology is the only feasible solution and applicable in harsh environments. In the development of a bubble level transmitter the company found the need for the development of a valve module, since no existing model in the market could meet the requirements of the project, as well as the need to develop several devices for testing of the system, to find for example optimized flows and the system response time in several scenarios. In most of the areas covered in the project few, or in some cases none, already conducted studies were located to base the project development. (AU)
