P719 Throat Width
This parameter is used to select the Throat Width of the flume when:
P700 PMD Type = 1 Exponent and P701 = 4 Parshall Flume. After
selecting the Throat Width the Exponent P717 and K Factor P 718 will be
set automatically.
Calculations
The following parameters P720 to P725 are values calculated by the unit,
dependent on application, and are “Read Only”, therefore have no default
values.
P720 Area
Displays the calculated value of the area when, P700 = 2 BS3690 flumes.
P721 Cv
Displays the calculated value for Cv when, P700 = 2 BS3680 flumes.
