  • Description: A remote telemeter using a power line and a telephone line is provided to improve the accuracy in a measured output by transmitting measured information containing a receiver number using the telephone line. A semi-transparent cover(2) is formed on a telemeter(1). A CCD camera(3) is formed on the cover. An LED(4) is formed at a side portion of the cover. A bimetal switch(6) is formed under the telemeter, while a heater(5) is formed on the telemeter. Number information is converted to a composite image signal by using a transmission module(7). The image signal is delivered to a telephone line model(11) through a power line(8). An external AC voltage is delivered to the power modem through a transformer(9) and a rectifier(10). Measured information containing the image signal and a receiver number is transmitted through a telephone line(12).
