Abstract

PURPOSE:To exactly monitor a state of water leakage or electric leakage, etc., by providing a means for executing a display or a remote transmission, when the integrating consumption quantity or the time, in case when the consumption quantity per a prescribed time is below a prescribed value, has exceeded a set value. CONSTITUTION:This meter is provided with a means for monitoring the integrating consumption quantity or the time in case when the consumption quantity per a prescribed time of water or electric power, etc. is below a prescribed value, and executing a display or a remote transmission of the relevant integrating consumption quantity or time, when said integrating consumption quantity or time has exceeded a set value. For instance, the quantity of use of water is integrated and displayed by an impeller 1, a permanent magnet 2, a magnetic sensor 3, an interface 4, a flow rate and rotational frequency converting circuit 5, an integrating counter 6 and a display part 7. Also, said display, etc. are executed by use of a circuit coctaining an integrating counter 10, an FF11, a timer 12, a delaying circuit, a flow rate lower- limit value setting circuit 14, a comparing circuit 15, AND gates 16, 17, an adder 18, a lower-limit flow rate integrating memory 19, etc.
