During normal operation, either cell could be knocked out of calibration (typically due to a slug of liquid). WinCCU, the host software, is capable of recalculating the volume based on the differences between the previous five point check and the current five point check.

  • Page 77: Checking Static Pressure (Sp)

    Checking Static Pressure (SP) The µFLO allows you to check the Static Pressure Calibration and log the pressure marker check points. It is recommended that checks of the Static Pressure (SP) be done prior to and directly following the calibration. During normal operation of the µFLO, the display provides continuous SP readouts.

  • Page 78: Checking Differential Pressure (Dp)

    Checking Differential Pressure (DP) As discussed above under “Checking Static Pressure (SP) Calibration”, it is recommended that checks of the Differential Pressure (DP) be done prior to and directly following calibration. You can enter as many DP pressure markers as you desire. Recording too many markers may cause the µFLO to overwrite existing older events.

  • Page 80: Zero Transducer

    Zero Transducer During the process of setting pressure markers to determine the need for a calibration of either the Static Pressure (SP) or the Differential Pressure (DP), you may conclude that the SP or the DP pressures are out of alignment exactly the same amount at each pressure marker (linear shift). When this occurs, you may either re-calibrate the µFLO or you may set the Transducer to zero.
