“…For both experiments, a common phenomenon to be characterized is the roofs' runoff, which is flow rate based. As indicated by Naveen et al (2020), regular commercial flowmeters tend to be expensive or only able to read in specific conditions. Arduino-based flow rate sensors, though inexpensive, may also not provide the adequate precision for such a small discharge.…”

“…In order to calculate the flow rate using a calibration curve, deflection must be measured using optical, piezoelectric, piezoresistive, or capacitive methods 13 . As an example of flow measurement with a cantilever structure, Naveen et al 14 created a stainless-steel cantilever along the pipeline to measure the flow rate at high volumes. Image analysis was employed to determine the cantilever's deflection.…”

In this study, a microfluidic cantilever flow sensor was designed and manufactured to monitor liquid flow rate within the range of 100–1000 µl/min. System simulation was also performed to determine the influential optimal parameters and compare the results with experimental data. A flowmeter was constructed as a curved cantilever with dimensions of 6.9 × 0.5 × 0.6 mm3 and a microchannel carved with a CO2 laser inside the cantilever beam. The fabrication substance was Polydimethylsiloxane. Different flow rates were injected using a syringe pump to test the performance of the flowmeter. Vertical displacement of the cantilever was measured in each flowrate using a digital microscope. According to the results, the full-scale overall device accuracy was up to ± 1.39%, and the response time of the sensor was measured to be 6.3 s. The microchip sensitivity was 0.126 µm/(µl/min) in the range of measured flow rates. The sensor could also be utilized multiple times with an acceptable error value. The experimental data obtained by the constructed microchip had a linear trend (R2 = 0.995) and were of good consistency with simulation results. Furthermore, according to the experimental and the simulation data, the initially curved cantilever structure had a higher bending and sensitivity level than a perfectly straight cantilever construction.

“…Low-cost sensors can be a good alternative for commercial sensors, but demand special attention to detail. As indicated by Naveen et al (2020), a flowmeter ideally should have an adaptable design and avoid fatigue characteristics. Though the ultrasonic sensor selected is not waterproof, meaning it can rust when operating under humid conditions, the module exposed to weathering can be replaced easily and inexpensively.…”

No matter how small the contribution of the present work when confronted to the whole of Science, for me it was an important journey. The journey was like a mountain ascension, only possible to summit because of the people who accompanied me. I thank my advisor, Prof. Brenda Leite, the guide of this expedition, who has been to this mountain and has enlightened the path. I also thank Prof. Rodolfo Scarati, whose advice and support shed light on this journey. I thank my previous research advisors,
