Performance Analysis of MP6 Micro Pumps (Piezoelectric Diaphragm) for Remote Automated Water Quality Monitoring

This research paper assesses the efficacy of piezo-electric diaphragm pumps in an automated remote sensor system intended for the detection of pollutant concentrations in water bodies. More precisely, this study aims to evaluate the pumps' operational efficiency when subjected to different angles and heights in order to replicate the roll conditions experienced by an unmanned small boat. To replicate the movement of the boat, experiments were conducted within a controlled laboratory setting and involved the use of a stepper-powered apparatus. Various static tests were conducted at different angles, while dynamic tests were performed by rotating the rig in a back-and-forth motion. The results show a slight decrease in the mean flow rate, going from 4.12 ml/min during static testing to 3.52 ml/min during dynamic testing. The findings enhance our understanding of the reliability and effectiveness of the pumps in relation to their intended use.
