Abstract

PROBLEM TO BE SOLVED: To increase an awareness of water economization by providing an integrating flow display section and a rate display section at the end of waterworks such as a faucet of a home. SOLUTION: When a faucet 7 is used, a momentary flow is detected by a flow meter 8 and an accumulated flow for a prescribed period of time is detected by an integrating flow meter 9 and displayed on a flow display section 11 and an integrating flow display section 12, respectively, making it possible to keep track of a tap water consumption condition while the faucet is used. And then a flow corresponding to the prescribed period of time is stored in a storing section 13, displayed on a result display section 14, and compared with the use for the same month a year ago for example. And then when necessary, a rate computation section and a rate display section are connected to the integrating flow meter 9, and an accumulated flow is converted into a rate, helping keep track of a tap water rate. In addition, all the integrating flow meters 9 are connected to a totalizing section to totalize and display an accumulated flow for each terminal, thereby making it possible to adjust a flow as an amount of a substance rather than sensually. Therefore, excessive use can be restrained and an awareness of water economization can be heightened.
