<p>The telemeter equipped with independent power source consists of a small turbine for generating electric power while it rotates due to a flowing of fluid such as water, oil or fuel gas etc.; a power amplifier for amplifying the low electric power provided from the small turbine; a rechargeable battery being charged with the electric power from the power amplifier, and supplying the charged electric power to individual components of the telemeter; a sensor for sensing a rotation speed, which is proportional to the velocity of the flowing fluid, of the small turbine, converting the sensed value into an electric signal; an A/D converter for converting an analog signal outputted from the sensor into a digital signal; a modem for transmitting the converted digital information on the amount of fluid flowed to the outside; a memory for storing information collected on every gauging operation; and a controller for controlling the operations of all the components, enabling a permanent gauging function without an additional power supplying from the outside by generating the electric energy necessary for operations of all its components.</p> |
