2. Spot sampling/profiling of these current and water quality parameters with the unit attached to a
laptop computer and the user present at the site during measurements.
For both of these applications, the primary reason for the user to purchase an ADV6600 – rather
than the SonTek Argonaut-ADV or YSI 6600 sondes individually – will be to correlate and combine
water current and water quality parameter data.
Common monitoring applications include:
• Monitoring of streams with variable flow, where changes in the speed parameter as a function
of environmental events (rainfall, etc.) are of primary interest.
• Monitoring of estuaries with reciprocal tidal flow, where changes in both speed and direction
are of primary interest.
• Monitoring of the velocity of wastewater streams to determine flow paths.
• Correlation of time of travel (TOT) measurements using the YSI rhodamine WT sensor with
stream velocity.
• Computer model verification of the movement of water and associated water quality parameters
in an estuary or bay system.
Common spot sampling applications include:
• Short studies to determine general water characteristics of a given area before, during, or after a
weather event.
• Computer model verification of the movement of water and associated quality parameters in an
estuary or bay system.
• Spot sampling during construction or dredging activities in order to define impacts on the
environment or to confirm compliance with standards.
I want to measure flow in a river. Is the ADV6600 the right instrument for me?
Probably not. The ADV6600 (like the SonTek Argonaut-ADV) measures velocity at a single point,
so it can be difficult to correlate this single-point velocity with the overall flow of a river. In order to
measure flow, users will usually be advised to purchase any of SonTek’s flow measurement
products (such as the Argonaut-SL or Argonaut-SW). These systems generate values of flow from a
computed water level and a mean river velocity and can be integrated with the YSI 6-series line of
instruments.
Can the ADV6600 be deployed from a buoy?
