Description
Technical field
The utility model relates to gas metering sensing device technical field, is specifically related to a kind of novel sensing device for gas metering.
Background technology
The Intelligent diaphragm gas meter of domestic gas metering use is generally used tongue tube or Hall as sampling sensor, common practices is that tongue tube or Hall are installed near character wheel of counter, a magnet steel is installed on character wheel of counter, rotation along with character wheel of counter, the magnet steel of character wheel the inside is also by close tongue tube or Hall far away and near, thereby generation pulse signal, when magnet steel along with character wheel near and far leave tongue tube or Hall time, pulse signal disappears, and intelligent gas meter gathers metering signal thus.A general pulse signal represents 0.1m3 or 0.01m3.
