As a result of economic, population, and consumption patterns changes, the use of freshwater has increased significantly in the last 100 years. Notably, measurement is essential to encourage water conservation. Therefore, this dissertation aims to contribute to the advancement of water meter technologies, specifically for measuring the volume of water drained in a pipeline of autonomous units in buildings. Thus, the present study aims to evaluate the applicability of a thin-film resistive sensor (bend sensor) with different coatings and lengths for implementation in individualized water measurement systems. In addition, the motivation of this work is to propose a volumetric meter using flow control valves that, ordinarily, are already present in the buildings hydraulic installations, thus avoiding the need for large-scale works in old buildings, which have collective measurement of water consumption. Methodologically, it is presented the system developed for the electromechanical and thermal characterization of the sensor, the computational simulation of the sensor performed using the Ansys software, and of the electronic circuit designed in LTSpice (trademark) software, the training of artificial neural network and the volume estimates from trapezoidal pulses. The results obtained allowed us to assess that, taking into account the type of coating, the sensor coated with polyester has better behavior for the proposed hydrometer. In addition, this evaluation allowed to conclude that the bend sensor demonstrated the feasibility to be used as a transducer of this volumetric meter and can be easily inserted inside a hydraulic component, as a flow control valve, for example.
