7.9 Flow Setup & Calibration
Menu location: Setup Menu → OEM Configuration → Flow Setup
The Flow setup menu includes the following options:
• Flow Options. Units of measure, a zero offset value, and the pipe diameter can be set from the Flow Options menu.
The pipe size must be set to allow for proper readings from the flow sensor .
• Custom Calibration. Some plumbing configurations may cause turbulent flows around the installed flow sensor and
cause the flow sensor to display inaccurate flows . Always check the actual flow of your system against a newly installed
Navigator flow sensor to ensure accuracy . If it is inaccurate, custom calibration can be performed to calibrate the flow to
read accurately . The custom calibration procedure is described below .
• Factory Calibration. This option can be selected to reset the flow sensor calibration to factory defaults.
Flow Options:
The Flow Options menu allows the user to adjust the display to show flow in the desired units . The available flow units
are GPM or LPM . Once the units are set, the flow will be converted in the controller and displayed in those units .
The other option in the flow setup menu is an option to set a zero cutoff value . In the case where the display occasionally
shows a low flow in the pipe when there is no flow (i.e. valve installed close to the pump), a zero cutoff may be useful.
Once a zero cutoff value is set, the controller will display a value of zero until it reaches the specified cutoff value and
then it will display normally . For example, if the zero cutoff is set for 20 GPM, and the flow in the line is 15 GPM, the dis-
play will show 0 GPM until it reaches 20 GPM in the line . There is also an Auto setting for the zero cutoff which will return
a zero flow rate whenever the valve is closed .
The flow options menu also includes the Pipe Diameter setting . For the flow sensor to work properly, the pipe diameter
must be set . It must be set before custom calibration is performed .
To adjust these settings, follow these steps:
6 . Navigate to the Flow Setup menu
RED or GREEN button to scroll through the list until the "Flow Options" option is highlighted
7 . Use the
8 . Press the ■ ENTER button to select Flow Options
9. The "Display Units" field will be blinking. The default value is GPM. To change the value to LPM, use the RED or
GREEN buttons . Press the ■ SET button to save the value . If you do not wish to change this, press the ■ NEXT button
to advance to the Zero Offset setting.
10. Now the "Zero Offset" field will be blinking. If a zero offset value is to be set, use the RED or GREEN button to
adjust the value to the appropriate zero cutoff value . Press the ■ SET button to save the value . If you do not wish to
change this, press the ■ NEXT button to advance to the Pipe Diameter setting .
11. Now the "Pipe Diameter" field will be blinking. Use the RED or GREEN button to adjust the value to the ap-
propriate pipe diameter . Press the ■ SET button to save the value . If you do not wish to change this, press the ■ DONE
button to exit the Flow Options menu .
