3. If desired, click the Add button to add more Calculated<br />
Flows data sets. Otherwise, click the Close button. The<br />
Calculated Flow data set will appear in the workspace.<br />
2100 Series Only - Calculate Flow appears as a data set<br />
under the first module in the workspace.<br />
Calculated flows are performed locally, which means that it is not<br />
necessary to have the flow measurement instrument perform<br />
this conversion and store the data until it can be transferred. As<br />
a result, data retrieval times can be reduced by collecting only<br />
primary data and not derivative calculations. Also, this feature<br />
may free memory partitions and extend number of days readings<br />
can be stored in the instrument.<br />
Note: If you alter the primary device of an existing calculated<br />
flow data set, the flow data already calculated will NOT be<br />
altered. You must first remove this data set and recreate it<br />
allowing the system to completely regenerate the calculated flow<br />
with the new primary device.<br />
Data Storage Setup -<br />
2100<br />
Use this window to configure the data storage rates for the<br />
measurement.<br />
Modules can store measurements at a Primary and Secondary<br />
rate. Primary rates are fixed intervals at which the module will<br />
store measurements. Secondary rates allow you to change the<br />
data storage rate if the measurements meet your defined<br />
conditions.<br />
Secondary storage rates are advantageous when you wish to<br />
examine measurement data in greater detail when a significant<br />
event occurs. Until the event occurs, the module stores data at<br />
the primary storage rate to conserve memory space and power.<br />
When the event occurs, the module preempts the primary rate<br />
and stores the data at the secondary rate. The secondary rate<br />
continues until the condition is no longer met (with a hysteresis).<br />
The examples below illustrate a few ways that secondary rates<br />
can be used.<br />
• Store data more frequently if the flow rate is greater<br />
than or equal to 100 gpm.<br />
• Don’t store data (primary rate OFF) until level is greater<br />
than or equal to 1 ft.<br />
• Store data less frequently if input voltage is less than 9<br />
volts.<br />
To configure data storage rates:<br />
1. Select a primary rate from the pull-down list. Note that<br />
selecting “Off” only disables the primary rate.<br />
2. Select a secondary rate from the “Store data every” pulldown<br />
list. Note that selecting “Off” disables the<br />
secondary rate.<br />
3. Set an equation that defines “When” the data should be<br />
stored at the secondary rate. This equation defines the<br />
