Comparative Design and Synthesis of IR and Optical Sensors for Fluid Flowrate Using FPGA

Accurate liquid flow rate measurements reduce the ambiguity in applied quantity of dosage, determine the leakage rates and increase system efficiency. The aim of this paper is to focus on the advantages of IR & optical sensors used with the FPGA technology. The two flowrate sensors based on IR and optical technology are designed and compared in the work on the basis of power consumption, delays taken in the processing, and required hardware. This paper also focuses on the FPGA platforms, their features and advantages over microcontroller and DSPs. The microstructured flowrate sensors are more suitable in chemical industries, commercial application where exact additive mixings, dosages play critical role.
