The flow computer memory usage varies with the number of flow runs that are enabled on the controller. The number of flow runs configured in RealFLO does not affect the memory usage.

The chart shows the non-volatile memory (NVRAM) used by the flow computer. The NVRAM used depends on these controller options:

  • the number of runs enabled
  • if Gas Transmission option is enabled
Controller Runs Available NVRAM C Program NVRAM Used Remaining NVRAM Used with GT Remaining

Notes

All memory for flow runs is allocated the first time the flow computer program runs. The memory does not change after this point.

As a result of the above, if an activation code is applied to change the number of flow runs, the flow computer program must be reloaded for it to take effect.

Measured figures are from Flow Computer 6.76. Other versions will vary slightly.
