The invention discloses a gas meter based on a fluid energy collector. The gas meter comprises a shell, a display meter head, a gas inlet, a gas outlet, pressure sensors and a processor, wherein the pressure sensors and the display meter head are all connected to the processor. The gas meter also comprises a micro-strip energy collector; a fluid inlet is independently communicated with the gas inlet and the inlet of each nozzle; the outlet of each nozzle is communicated with each miniature cavity; a flow resistance body is positioned on the position corresponding to the outlet of each nozzle in each miniature cavity; the micro-strip is positioned in each miniature cavity, is positioned on one side of each flow resistance body and keeps a set distance with the flow resistance body; a fluidoutlet is communicated with the inner side of each miniature cavity and the gas outlet; the micro-strip is a piezoelectric function film material, wherein at least two pressure sensors are arranged, and the micro-strip supplies electric energy to the pressure sensors, the processor and the display meter head. By use of the gas meter, the micro-strip energy collector is adopted to provide energy for each electricity utilization component, a battery does not need to be replaced, and maintenance cost is effectively saved.
Description
technical field [0001] The invention relates to a wireless gas meter, in particular to a gas meter based on a fluid energy collector. Background technique [0002] Existing gas meters generally use batteries for power supply, so it is necessary to regularly replace the batteries for maintenance of the wireless gas meters, which consumes a large maintenance cost. In addition, at present, when reading the meter, it is usually necessary to get off the vehicle and go to the gas meter to read the meter, which takes a lot of time. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention aims to provide a gas meter based on a fluid energy harvester, which adopts a microstrip energy harvester to continuously provide energy for each electric component without replacing batteries, effectively saving maintenance costs. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] ...
