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.

3.6.5 Programming advanced settings
Use steps as in section “Log-in and Primary Pages” to navigate to the Programming page. Refer to Figure 72 for the Path
configuration options.
1. Highlight [Composite] and press [ENTER]. Scroll down and select [Advanced] and press [ENTER].
2. Select [Inputs] and set the process [Fluid Temperature]. The Fluid temperature can be either fixed/static (average process
fluid temperature) or can be live values read from an Analog input or RTD (available as an option).
3. Also set the [Ambient Temperature].
4. The [Transmit Voltage] should be set based on the viscosity of the process fluid and Pipe size. High viscous fluids or large
pipe sizes may need high voltage setting for signals to pass through.
5. Choose the [Refresh Rate] based on how fast you want the meter should make a measurement. The refresh rate selection
will not change the update rate on the Analog or Digital outputs. The Analog output and Digital outputs are always
updated at 4Hz.
