Note
Each piping diameter above is determined to go with the respective piping sockets of the OPSA-
150. If the measuring unit is installed in an area far from the water sampling point and drainage
point, each piping diameter should be larger than that indicated above.
Ensure that the waste water piping, overflow piping (1) and (2), and drain piping have sufficient
gradient to allow drainage from the outlet of each pipe. Ensure that the end of each piping is not
immersed in water.
When using soft PVC piping, use the braid reinforced flexible PVC (pressure-resistant) type.
It is useful to use removable pipe tubing for regular cleaning.
