3.6.4 Programming the Flow and Diagnostic Limits
Use steps as in section “Log-in and Primary Pages” to navigate to the Programming page. Refer to Figure 71
for the Path configuration options.
1. Highlight [Composite] and press [ENTER]. Scroll down and select [Limits] and press [ENTER].
2. Program the minimum flow velocity in [Min Velocity] and maximum flow velocity in [Max Velocity].
3. Program the appropriate velocity warning limits in [Min Vel Warn Limit] and [Max Vel Warn Limit].
The values programmed in the warning limits should be tighter than those programmed in
[Min Velocity] and [Max Velocity] for early warning indications on the LCD and Errors.
4. To cutoff the near zero measurements program an appropriate value in [Zero Cutoff].
d. In order to see stable averaged flow, program the time window for which flow should be averaged in
[Flow Averaging]. For example if a value 16 is programmed in for [Flow Averaging], the flow value will
have the average of the last 16s of flow values. This allows the flow values on the display and the
outputs to be less noisy.
5. If in section “Programming the Fluid” on page 62, Tracking was selected as OFF, program the
[Soundspeed Error %]. This configuration will be used to validate if the measured sound speed is
within the programmed range of the nominal sound speed. In case the measured sound speed is
outside the [Soundspeed Error %] of the nominal sound speed a E2: Soundspeed Error is reported.
