Dover ProGauge MagLink LX 4 - Pipe Stiffness Calibration Procedure

3. Volume/length: You can keep the default value (automatically given when a Pipeline is selected
above) or, manually enter a specified value.
NOTE: If you enter a value manually, make sure you use the correct units of measure.
4. Minimum Test Pressure: This is the minimum pressure in the pipeline during the leak test. Usually
the pipeline pressure is more than 20 psi. It is recommended to keep the default value.
5. Minimum Dispensing Pressure: This is the minimum pressure in the pipeline during normal
dispensing.
6. Beta: Pipe stiffness in psi and pipe material can have an effect on pressure calculations. Refer to the
"Pipe Data" tables at the end of this Appendix. These values are theoretical.
7. Calibrated Beta: This is the pipe stiffness in psi that has been calculated by the console’s algorithm
during the process “Beta calibration” (internal process that can calculate the pipe stiffness through a
controlled leak in the system). The system uses the Calibrated Beta value for the leak rate calculations
once it has been calculated and shown on the field here. If there is no Calibrated Beta value, the
system will use the theoretical Beta for the leak rate calculations.
8. RESET button: If you click the RESET button, the Calibrated Beta value is erased and the system will
use the theoretical Beta for the leak rate calculations.
9. To open the "Calibrate" panel, select the arrow on the right side of the colapsed panel.
Calibrate
The system can calculate pipe stiffness in the "Calibrate" panel. The user must start a controlled leak in the
system for the calibration to occur.
10. Leak generator (gph): Enter the type of the leak generator. The most common leak generators can
start a 3 gallon per hour (gph) leak at 10 psi.
11. Number of calibration cycles (3-12): During each calibration cycle the system will pressurize the
STP. It will then stop the STP and record the pressure in the line. It is recommended to complete the
maximum number of cycles (12) for the best calibration results.
12. Start calibration immediately: If this slider button is enabled (pushed to the right and shown in
blue), tthe system will then start the calibration sequence awhen the START button is clicked.
If the slider button is disabled, when the START button is clicked: the system waits for the dispenser
nozzle to be picked up momentarily, then be put back into the cradle. This will cause the system to
start the calibration once the nozzle is back into the cradle. This method is used to start the calibration
