Flow Measurement Solution for Sewer Grid Monitoring

Finding an inflow and infiltration solution.

A flow measurement solution was required for an inflow and infiltration application in a sewer network system. Our MantaRay portable area velocity flow meter can be used for flow surveys in partially-full, full, and surcharged sewer pipes. The single submersible sensor with no moving parts mounts to the bottom of the pipe or channel, and the meter is easily configured for the end user's needs by entering the channel shape and size on the user-friendly keypad interface. The MantaRay has a built-in 2-million-point data logger that gives the date and time-stamped flow values from 10-second to 6--minute intervals. This data can also be captured when the sleep mode function is activated.

In the case of this application, it was also suggested that they use the corresponding pipe bands for mounting the QZO2L sensors in the sewer. The pipe bands were installed at various points in the sewer system with the MantaRay to sample flow. The compiled data was helping to determine areas of concern where the pipe might be cracked or deteriorated, allowing for groundwater infiltration into the sewer system, and did so successfully!
