Output
Flow (Q Main) Flow rate calculated from cross-sectional velocities 
Q Manning Flow rate calculated with Manning formula, for flow depths that fall below
the velocity profiling range

Smoothed flow Flow data with smoothing applied. 
Totalized flow Total flow, including both positive and negative flow. 
Velocity (Raw Velocity) Average of individual point velocities from all velocity beams. 
Avg. Velocity Flow divided by cross-sectional area 
Smoothed Velocity Velocity data with smoothing applied. 
Main Depth (Level) This is the depth used for flow calculation, after comparing the readings
from the primary depth sensor with the readings from the secondary depth
sensor.

Ult. Depth Liquid level from ultrasonic depth sensor 
Sec. Depth Liquid level from secondary depth sensor 
Smoothed Depth Level data with smoothing applied. 
