| 摘要 |
The invention relates to a cold and hot water and heat meter meant for household or industrial consumers. According to the invention, the meter consists of a body (), known per se, to which an electronic adder () is attached to receive some input signals, through a bus (), from a multi-sensor structure () attached to a stage () for the measurement of nominal flow-rates and/or to receive input signals through another bus () from another stage () for the measurement of low flow-rates, the water flowing from an inlet zone () towards an outlet zone (), the signals generated by a temperature sensor () for the supply pipe and a temperature sensor () for the return pipe being taken over by a temperature measuring block () which communicates through another bus () with the electronic adder () which consists of a block () for amplifying and comparing the signals generated by the multi-sensor structure (), the said signals being then converted into numerical values by an analogue-to-digital conversion block (), the numerical values being afterwards processed by a computer unit () and the processing results being displayed on a display device (), by means of a decoding circuit (), and remotely transmitted by an RF communication module (). |
