Abstract
The paper presents a method of estimating the failure rate by applying the extrapolation method, for the case of a single jet cold water meter. The predictive reliability of a system (water meter) is the reliability expressed by the reliability indicators resulting from forecast calculations based on the reliability of the component elements. In order to analyze the reliability of the considered water meter, it is divided into component elements or blocks of elements, which are functional or constructive units, whose reliability indicators are determined in operation. The water meter must be seen as a complex product, the structure of which includes a number of elements forming a system comprising a series of elements connected in one whole, that fulfills a specific technical function. The logical connection of the elements and the component blocks gives the logical reliability scheme with the subsystems and structural elements of the pressure measuring means. Finally, the logic mechanical reliability scheme of the water meter is determined, this being analyzed as a functional complex system, expressing the link between the reliability of the component elements and the reliability of the system as a whole.
