The development of a solid state wind velocity and direction indicator, suitable for data logging

Abstract

This thesis describes the development of a free standing, maintenance free anemometer which has no rotating parts. The principle of operation is based on the \-vind drag/force around a hollow P.V.c. pipe. The aim is to demonstrate how the strain occurring in the P.V.C. pipe, due to wind drag/force acting on it, can generate an electrical signal which can be mathematically manipulated to determine wind velocity and wind bearing.
