大口径供水计量流量计通常包括用于源水计量的流量计和出厂水计量的流量计,其中水厂的源水计量是供水计量的起点。引至水厂的源水通常采用一组水泵加压由源水输水管线输送到水厂沉淀水池,用于源水计量的流量计多数安装在源水输水管线。经过各种制水工序,加压泵站将制成水通过输水管道送入城 Large-diameter water supply metering flow meters typically include a flow meter for raw water metering and a flow meter for factory water metering, where source water metering at the water plant is the starting point for water metering. The source water leading to the waterworks is usually fed by a group of pumps and pressurized by the source water pipeline to the sedimentation basin of the waterworks. Most of the flowmeters used for source water metering are installed on the source water pipeline. After a variety of water processes, pressurized pump station will be made into water through the water pipe into the city
