If the profile chosen is any other contents profile, press the red button ↵ to save the profile to memory
and automatically scroll on to the next main menu option “Cont @ max”, Refer to Section 4.4.9.
4.4.5 Power factor for the chosen flow law. Screen display: P.FACt
Factory default value: 1.000
This selection is offered only if the user has chosen a duty of Flow which requires the manual entry of a
power factor in a formula of the type
Flow Q = kh* (where * = the power factor)
or is shown when manually navigating the main menu - ignore if duty chosen is Level, Distance or
Contents.
The MSP400 is pre-programmed with the appropriate power factor for many of the flow profile options
available, or it may be edited to suit the user’s specific flow structure.
Refer to Appendix C for a table of pre-programmed values.
To edit the power factor
a) Press the blue button → to enter the “P.FACt” menu and to display the current power factor in use. If
this is correct, press the green button ↓ return to the main menu.
If the power factor is to be edited, press the blue button → again to allow editing
The leading digit of the current power factor will now be flashing, indicating it may be changed.
b) Use the green button ↓ to edit the value of the leading digit.
c) Once correct, use the blue button → to select the next digit and then the green button ↓ to edit as
before, or the blue button → to move to the next digit. Continue this sequence until all 5 digits are
correct.
d) Press the blue button → a final time to confirm the new value. None of the digits should now be
flashing.
If the new power factor value is incorrect, the edit sequence for the power factor can be re-started by
pressing the blue button → again.
If the new power factor is correct, press the red button ↵ to save the new value to memory and
automatically scroll on to the next main menu option: “SCALE”
4.4.6 K Factor for the chosen flow law Screen display SCALE
Factory default value 1.000
Note:
The display will read “SCALE”. If a flow duty has been chose, the value entered into this parameter is in
effect the K factor in a flow law of the form Flow Q = kh*.
If a Distance, Level or Contents duty has been chosen, the value entered into this parameter is a factor
by which the measured distance, level or contents is scaled.
For a Level or Distance duty the scaling factor is normally left at the value calculated by the MSP400
depended upon previously entered data and the duty chosen, or the default value of 1.000, unless the user
wishes to convert the measurement to units other than those offered as standard, for example, yards.
For a linear Contents duty, the user must enter a scaling factor to convert the level measurement to a
contents measurement. If the units of measurements are “m”, then enter the volume contained in 1m of
liquid height in the tank. If the units of measurements are “ft”, then enter the volume contained in 1ft of
liquid height in the tank.
