A system for detecting and metering wind energy and recording the total integrated energy or power levels over any desired period of time. The system emphasizes simplicity of design to achieve: a transducer sensitive to the presence of winds that embodies a means of generating a voltage which is a function of the wind velocity; a means of selecting the minimum wind velocity threshold for the initiation of metering, and rejecting velocities above a selected upper velocity cutoff point; a means of computing which directly converts the wind velocity function voltage to an energy-density analogue voltage which can be programmed to replicate the performance of wind turbines or other wind powered devices and to scale the energy density to the units of energy or power desired; a means of recording which provides a record of the sum-total of the wind energy or power levels measured whose instantaneous values are integrated continuously over a desired period of time and which may be read directly and reset for each period; and an optional means of monitoring and calibration of the system. The recorded data is measured in such values as are directly related to the potential electrical, mechanical or thermal energy that would be generated at the site of installation by any of a variety of typical wind turbine generators. Because of the system\s completeness, simplicity and implementation, may be self powered and accurately computes and records the data in units of wind energy or power; it may be economically produced and employed at much less cost, with better utility and reliability than prior art instruments.
