A Device for Checking Water Meter without Power and a System for Checking Water Meter Having the Same

摘要

The present invention relates to a water meter reading apparatus and a water meter reading system which are connected to a water meter to meter water usage and the like, and more particularly to a water meter reading system including a central processing unit, a storage unit and a terminal connection unit, The power is supplied from the terminal and operated only when the terminal is connected to the terminal connection unit for meter reading of the water meter, so that a separate power supply unit is not required, so that there is no problem such as discharge and the power used can be minimized , The storage unit can accumulate and store the meter reading information by date so that the meter reading information of the meter reading date and the meter reading date can be confirmed so that the information on the meter reading history is confirmed if necessary and the malingering of the meter reading source is prevented The meter reading information may include cumulative usage information of water, instantaneous flow information, Information on water usage, instantaneous flow rate information, leakage information, unused information, and backflow information for a certain period of time can be generated by including the water usage pattern, the failure frequency of the water meter, The present invention relates to a non-electricity water meter inspection apparatus and a water meter inspection system equipped with the same.
