Introduction 1-3
The ADS Flow Monitoring System
The ADS flow monitoring system is a comprehensive and sophisticated system that
uses powerful scientific and engineering concepts to measure and monitor open
channel flows. The system was initially developed in the late 1970s and has been
used to address a variety of issues faced by municipal sewer systems, such as:
planning sewer systems (for example, sewer sizing, and sewer rehabilitation),
reducing infiltration and inflow (I/I),
monitoring combined sewer overflows (CSO),
monitoring surcharges,
calculating billings, and
monitoring sewage handling facilities (such as wastewater treatment plants
and pump stations).
Flow Monitoring with the QS3600
The main role of the QS3600 flow monitor in the ADS flow monitoring system is to
measure the flow rates in sewer lines. In this application, readings are taken by flow
sensors installed in the sewer pipe, then gathered and processed by flow monitors
connected to the sensors and installed in the manhole. Using a telephone line, the
data is transmitted to the central computer via a modem and then processed by
QuadraScan software. QuadraScan uses the data to generate reports on the quantity
of flow.
