520			_aTranscripción del abstract original del autor: Tokyo Gas has developed a new gas meter called the Thermal Flow Meter. The operating principle of this meter is heat transfer, but what makes it different from any other meter is the fact that it positions its thermal sensors near the inner walls of the pipe. This at first might seem to be a ridiculous way of measuring flow, but in the following pages we will explain about how accurate flow measurement was accomplished, and also how, compared to gas meters now in use, we were able to make it much smaller, light weight, and even cheaper. Furthermore, the most important advantage of this new meter is that it can accurately measure the amount of heat value flow rate of natural gases. This fact enables the Thermal Flow Meter to become a "calorific flow meter".
