The results are subsequently expressed in terms of the mean flow velocity, thereby providing its potential utility in pipes of other dimensions.

The performance of the prototype sensor has been evaluated after building an appropriate regression model. In practice, the angle can be sensed using simpler methods. To experimentally evaluate the sensor in detail, the mean deflection angle of the cantilever is measured using a camera, and an image processing algorithm. One of the ends of the cantilever is firmly fitted to the inner wall of the pipe, and it bends or deflects towards the direction of the flow as a function of the flow rate. A cantilever formed using a thin stainless-steel strip is used as the sensing element in the proposed sensor. Such sensors are reported for micro-fluidic applications but its potential application in large diameter pipes under turbulent flow has not been studied yet. Evaluation of a low-cost, cantilever-based sensor, suitable for measuring flow rates under turbulent flow conditions is presented in this article. Low-cost and accurate flow sensors with bidirectional sensing capability have numerous applications in the residential and irrigation sectors. Most of the existing flow sensors are expensive and limited in their capabilities for sensing bidirectional flow. The results demonstrate that the meter provides accurate and repeatable results, mostly indistinguishable from the results of a much more expensive meter. The design is based on an orifice plate, to leverage the Venturi effect, which causes a measurable pressure drop. In this paper, a novel low-cost water flow meter is developed for use in household smart metering solutions. Smart meters address many of these challenges by enabling electronic and real-time metering, but are still prohibitively expensive. Moreover, billing information, which serves as feedback, lags consumption by several weeks. Existing metering solutions are often manually read by officials, and the information difficult to digest. One way to affect prudence with this scarce resource is to generally create timely awareness of consumption thereof, and also the related cost for the consumers. A lot of focus, especially in drought-stricken countries, is placed on water conservation. The availability and depletion of natural resources is increasingly punted as the limiting factor for sustainability.
