System Overview
The ADS ® FlowShark ® flow monitor uses three flow measurement
devices to gather raw flow data: a quadredundant ultrasonic depth
sensor, a pressure depth sensor, and a Doppler peak velocity sensor.
The ultrasonic and pressure depth sensors apply independent
measurement techniques to collect information used in flow depth
calculations. The Doppler velocity sensor gathers peak flow
velocity data.
The monitor receives the raw flow depth and velocity data from the
sensors based on a defined time interval and then processes the
data, which may involve calculating the flow rate. The monitor
memory can store over 140 days of data logged at a 15-minute
sample rate. This data is available to the user for collection, further
processing, analysis, and reporting. These reports can assist
municipalities and other industry in planning improvements and
additions to sewer systems, improving the accuracy of billing
information, and providing information for the overall management
of sewer systems.
The FlowShark monitor and sensors are primarily designed for
monitoring flow in sanitary and storm sewers. The monitor mounts
to the manhole rim or wall slightly below the manhole cover; the
sensors typically attach to a ring installed in the sewer pipe a short
distance upstream from the manhole invert. The FlowShark monitor
can support a complete complement of flow sensors at a single or
dual monitoring points. These sensors display exceptional durability
and accuracy, even under harsh and turbulent flow monitoring
conditions.
