How to Edit the [Estimated Vs m/s] (liquid sonic velocity)
During transducer installation, the meter bases its initial transducer spacing recommenda-
tion on the value stored in this menu cell. [Estimated Vs m/s] allows you to review and modify
(if necessary) the Vs value for the liquid class you selected.
After you install the transducers, the computer will measure Vs directly. If the displayed
(or edited) Vs stored in this menu cell is accurate, the transducers will be spaced correct-
ly. This will eliminate the need to re-space the transducers after their initial installation.
If the estimated Vs is substantially different from the measured value, the flow computer will
request that you re-space the transducers during the transducer install procedure.

NOTE: During the Xdcr install procedure (see paragraph 2.4), you can ignore a
respacing request by pressing the <Down Arrow> instead of <ENT>. If this
triggers a Spacing Alarm, check [Diagnostic/Data/Site Setup Data] to make sure
the measured Vs value does not exceed the Vs max or Vs min items.
To edit the Estimated Vs m/s:
To activate numeric entry press
Using PC numeric keys or Magnetic Wand, enter the sonic velocity value using
meters-per-second.
To register the data press
How to Edit the [Viscosity cS] Setting
The [Viscosity cS] menu cell shows the kinematic viscosity of the selected liquid (in centi-
stokes). The viscosity value is particularly important for high viscosity liquids. The meter
requires an accurate liquid viscosity to compute the flow profile compensation. If the dis-
played viscosity is correct, bypass this menu cell by pressing .
To edit the Viscosity setting:
To activate numeric entry press
Use PC numeric keys or Magnetic Wand to enter the Viscosity value, which must be
in centistokes.
