Note: IETG also recommends performing confirmations
to verify the accuracy of the data and equipment.
Confirmations involve comparing manual flow depth,
temperature, and velocity measurements taken in the field
against monitor readings taken electronically. The
technician or analyst confirms the accuracy of the data
based on the difference between the monitor and field
readings. For more information, refer to the Profile User’s
Guide #950015 (version B4 or higher).
