Metering method for user water consumption of circulating water supply system
The invention relates to a metering method for user water consumption of a circulating water supply system, which comprises the following steps: arranging a fluid meter between a water inlet pipe and a water return pipe, wherein the fluid meter comprises a water inlet metering pipe and a water return metering pipe, the water inlet metering pipe is arranged on the water inlet pipe, and the water return metering pipe is arranged on the water return pipe; respectively calculating a first propagation time difference and a second propagation time difference of the ultrasonic waves propagating in the water inlet metering pipe and the water return metering pipe; calculating a water inlet instantaneous flow rate and a water outlet and return instantaneous flow rate; and judging whether the water inlet instantaneous flow rate is smaller than the water return instantaneous flow rate or not, if yes, comparing the first error percentage with a first set value, if not, comparing the second error percentage with a second set value, if the second error percentage is larger than the second set value, metering, and otherwise, not metering. The metering accuracy of the water consumption of the user can be effectively improved.
本发明涉及一种循环供水系统的用户用水量的计量方法，包括以下步骤：在进水管和回水管之间安装流体计量表，流体计量表包括进水计量管和回水计量管，进水计量管安装在进水管上，回水计量管安装在回水管上；分别计算出超声波在进水计量管和回水计量管内传播的第一传播时间差和第二传播时间差；再计算出进水瞬时流量和出回水瞬时流量；判断进水瞬时流量是否小于回水瞬时流量，若判断为是，则将第一误差百分比与第一设定值进行比较，若判断为否，则将第二误差百分比与第二设定值进行比较，若第二误差百分比大于第二设定值，则进行计量，否则不进行计量。本发明能够有效提高用户用水量的计量准确性。
