Description

technical field [0001] The invention belongs to the technical field of water meter processing and relates to a passive wireless centralized reading water meter. Background technique [0002] The remote water meter is a kind of water meter developed by many manufacturers to solve the difficult problem of meter reading when the prepaid water meter is in an embarrassing and depressed state. Prior to this, meter reading was basically done by means of pulsed remote transmission of power supply. Because this type of water meter needs to be powered for a long time, the failure rate is extremely high and the maintenance cost is expensive. At present, it is basically in the phase of elimination. It is replaced by "wireless passive centralized water meter". For this type of water meter, due to the problem of difficult wiring in wired remote transmission, especially in old urban areas, the workload of wiring and later maintenance is relatively large, so you can choose to use wireless c...
