10.5.2 Computation Commands
The Index Velocity and Discharge Commands Computation commands IB,
IS, and IV are used to compute the index velocity (rated mean velocity
based on the Channel Master’s velocity profile data).
IB - Bank
Purpose Used to indicate whether the Channel Master is mounted on
the left bank or right bank.
Format IBn
Range n = 0 (left), 1 (right)
Default IB1
Recommended Setting. Set using WinHADCP.
Description the IB command is used to indicate whether the Channel Mas-
ter is mounted on the left bank or right bank of the channel.
This is necessary since the Channel Master outputs negative
velocity for downstream flow if the Channel Master is
mounted on the left bank.
IS - Select Velocity Bins
Purpose Used to select the cells that are averaged as part of the input to
compute the rated mean velocity.
Format IS n, B (IS0 = help)
Range n = 1 to 99
B = desired Bin number (1 to 255)
last entry B = 9999
Default IS 1,9999
Recommended Setting. Set using WinHADCP.
Description The IS command is used to select the cells that are to be aver-
aged as part of the input to compute the rated mean velocity.
It is possible to select a range of cells or a list of individual
cells.
To select a continuous range of cells, use the command IS
100, B1, B2. Here, 100 indicates that a range of cells from B1
to B2 are to be used. Therefore, the command IS 100, 1, 20
selects all cells from 1-20 to be averaged together.
