WATER FLOW METER SYSTEM USING MANY FLOW METERS

摘要

PURPOSE: A water flow meter system using many flow meters is provided to stably supply water by detecting the abnormality of one flow meter using many water flow meters and operating the other normal flow meter. CONSTITUTION: When a contact sensor(224) is closed to a level weight of a flow meter(222) by generating a fail in a water flow meter(22), the contact sensor(224) outputs by detecting the fail and by generating a fail signal. A control unit(25) generates a control signal for driving the other flow meter(24) by responding to the fed fail signal, and outputs the control signal to a solenoid valve(26). The solenoid valve(26) operates a water flow meter(24) by generating a driving signal to drive an air water valve(28). Therefore the flow meter(24) is operated by the air water valve(28), and is able to normally display the amount of water flowed from outside. The water flowed through the water flow meter(24) is supplied to an external equipment system through an output terminal OUT by passing a pipe(210).
