WATER SPOUT DEVICE WITH FLOW METER, CHANGEOVER COCK WITH FLOW METER, FLEXIBLE WATER SPOUT PIPE WITH FLOW METER, FLOW METER FOR WATER PURIFYING-ACTIVATING INSTRUMENT, COCK WITH FLOW METER FOR UNDER-SINK TYPE WATER PURIFYING-ACTIVATING INSTRUMENT, AND FLOW METER UNIT

摘要

PROBLEM TO BE SOLVED: To enable simply and posteriorly install to various water purifiers having different specifications such as a cartridge lifetime and to correspond to approximately all water purifying-activating instruments while accurately displaying the residual lifetimes of the cartridges corresponding to specifications by precisely measuring the integral flow rates or the like of the water purifying-activating instruments. SOLUTION: The changeover cock with the flow meter has a purifying-activating water inflow port 111, a purified-activated water discharge opening 112, a body case 110 with a purified-activated water passage 113 and a flow meter unit 120 being arranged in the passage 113 for the case 110 and measuring the integrated flow rate of purified-activated water passed through the passage 113. The total filtering flow rate of the cartridge for the water purifying-activating instrument is set by a micro computer 151 and an operating section 152, and the micro computer 151 is constituted so that the residual lifetime of the cartridge for the purifying-activating instrument is operated arithmetically in response to the rate of the integrated flow rate to the set total filtering flow rate and the residual lifetime of the cartridge for the instrument is displayed to a liquid-crystal display section 154.
