VERY IMPORTANT NOTE: MAKE SURE YOU ALWAYS USE 1.0 SG PRIOR TO TUNE
2. Select “Smartflow Tune” and wait for tune to be completed. Exit the Wizard.
3. Go to Parameter Group 85, View, AND document the values populated in Parameters 85.01, 2, and 3. Note these
values are values at the .85 SG of the liquid that the pump just ran the tine function with. They will need to be
converted to water like, to 1.0 SG.
4. Using each of the values from step 3, divide each by the SG value of .85 and revise the values in parameters 85.01,
2, and 3 to the higher values calculated. Exit this group and go to group 77.
5. Use the newly calculated value of 85.03 and change the value of parameter 77.06 to the newly calculated value of
85.03 (PSO100%)
6. Change value of Parameter 78.03 to .85. If you have a variable SG follow the guidelines as outlined in the Manual
for the Smartflow Wizard.
Note:
This example uses a Specific gravity lighter than water. If the liquid you are performing a Smartflow tune on is heavier
than water, you will need to also DIVIDE the values from step 3 above and use these newer values. The water like val-
ues needed should be lighter than the values recorded during the tune.
Smart TDH (Sensorless Total Dynamic Head)
The PumpSmart PS220 can calculate the Total Dynamic Head (TDH) of a pump using information configured using the
Advanced Smartflow Wizard. Individual Suction and discharge sensors or a Differential Pressure sensor are required to use
this functionality. Should the pumping system maintain a relatively stable suction pressure (+-5%) the additional sensors
will not be required.
Refer to the Advanced Smartflow section for more detailed information on this requirement.
Smart TDH PID Control
The PumpSmart PS220 can regulate to the TDH of a pump using the information gathered when running the Advanced
Smartflow Wizard. It will require the Control Mode configured using the Process Control Wizard to be set to Smart TDH.
To access the Process Control Wizard from the Home View, follow the path:
