Abstract

PURPOSE:To enable the detection of inverse setting of a city water meter in a normal state of use, by detecting a high-frequency pulse generated by a pulse generator when a blade wheel rotates reversely, so as to determine the reverse rotation. CONSTITUTION:In the case when a city water meter 1 is set normally, a pulse voltage generated between the opposite ends of a resistor 7B of an amount detecting unit 7, which is shown in Figure B, is counted by a counter circuit 7D and a count value thereof is displayed 7E. In the case when the meter 1 is set inversely, a pulse voltage shown in Figure B is generated between the opposite ends of the resistor 7B of the amount detecting unit 7. A band-pass filter 7G whereby the frequency of a high-frequency pulse of Figure B (e)-(f) is allowed to pass but the frequency of a pulse of Figure A is not allowed to pass, is provided. When a pulse passes through this filter 7G, a reverse rotation detecting circuit 7F detects the passage makes it displayed 7E that the meter 1 is in the state of inverse setting.
