This is an independent lab that performs water analysis, including ´ industrial waste waters. The fluid sampler has to work autonomously and be capable of collecting the specified fluid volumes at the configured frequency. The budget for building the prototype is 300 e. This dissertation provides, first, an overview of similar fluid sampler devices currently available on the market as well as of the relevant guidelines and regulations regarding waste water sampling in Portugal. Then, it presents the platforms used and, finally, describes the complete development process of the fluid sampler. The highlights of this project are the design and development of the fluid sensor and of the overall control system, the selection of universal materials and the simplicity of the water divider system. Together they create a low-cost, fully functional and easy to use and maintain automatic fluid sampler.engAutomatic Fluid Sampler Sensor Peristalticmaster thesis201273578
