3 Measuring equipment of consuming volume of domestic water by three kinds of time band

摘要

PURPOSE: A tap water metering apparatus is provided to distribute the request for water by discounting the water charge for night time, while reducing water consumption and allowing water flow data to be easily obtained. CONSTITUTION: Voltage or current signals(10,12) which are output from an electronic flow meter or ultrasonic flow meter, pulses(30,33) and a communication data are converted into predetermined sized by signal matching units(11,13) and input to a micro processor(1). The input value is multiplies by flow converting coefficients so as to be converted into an actual flow amount. The converted flow amount is distributed to a separate integrator by a distributor in accordance with the set time. Thus, the amount of water consumption is metered separately through a day time integrator, a night time integrator and a midnight integrator, respectively.
