Chapter 1 1.1 Software Overview HERMIT® 3000 VS. THE VIRTUAL HERMIT® AQUIFER TESTING KIT Virtual HERMIT software, when combined with Level TROLL® 700 instruments, mimics the pump test functionality found in the original In-Situ HERMIT® series of loggers. On the original HERMIT platform, up to 16 analog pressure transducers were connected to the HERMIT logger, which both logged the data and provided the user interface, as shown in Figure 1. FIGURE 1.
Today, the Virtual HERMIT software works with Level TROLL 700 instruments and the Rugged TROLL® Net Hub to provide similar functionality in a different set of tools (Figure 2): • The Virtual HERMIT software provides the user interface via the laptop computer. • The Rugged TROLL Net Hub connects multiple Level TROLL 700 instruments to the laptop. • The Level TROLL 700 instruments log the data.

and downloading all the data sets simultaneously using the Virtual HERMIT software. When using the RuggedReader and Win-Situ Mobile to collect data, the data logs are synchronized back to the laptop using Win-Situ® Sync. Virtual HERMIT software automatically imports the data. 1.2.
1.3 SOFTWARE CONCEPTS The Virtual HERMIT software organizes a named “Pump Test” into one or more “Virtual HERMITs”. Each “Virtual HERMIT” may have between 1 and 16 Level TROLL instruments (Figure 4). Each Level TROLL will have a standard Win-Situ data log associated with it. FIGURE 4.
Chapter 2 Getting Started Each Level TROLL used with the Virtual HERMIT software must be configured to a unique network address. When ordering from In-Situ Rentals, the Level TROLL instruments will arrive pre-configured and ready to use with the software. After initially installing and opening the software, the list of named pump tests will be empty. When creating subsequent pump tests, you will see a list of the pump tests that have already been created.
All the Pump Test log files are downloaded to the Win-Situ 5 working directory’s “Site Data” directory—just like in Win-Situ 5. Also note: • Delete—Be careful! If you “Delete” a Pump Test, the Pump Test configuration and the data logs associated with it are also deleted from your hard drive. • Discover—If you install the Virtual HERMIT software on a computer other than the one used to create the Pump Test, you can discover the Pump Test with this button.
2.3 ADDING A VIRTUAL HERMIT Next Add a Virtual HERMIT by clicking the “Add Hermit” button. You can add any number of Virtual HERMITs to the Pump Test. Select the Virtual HERMIT icon on the left window. This will activate the Virtual HERMIT windows on the right as shown below. By default, the Summary screen is the first selected tab. 2.4 ADDING A TROLL Note: Always use the “Add/ Select the Virtual HERMIT added in the previous step (on the left window Find TROLLs” button before pane).
The Add Wizard will be activated. The Add/Find wizard has three different modes as follows: • Search for one or more Level TROLLs on an existing network • Build a new network using a TROLL Net • Add a new Level TROLL to an existing network 2.4.1 Search for One or More Level TROLLs on an Existing Network This is the option you will use for the Level TROLLs provided from In-Situ Rentals.
1. After selecting the Search option, click the Next (arrow) button. The wizard will prompt you for the serial port and the number of TROLLs to configure. • If you do not know the serial port that the TROLL Net Hub is plugged into, then use the first option to search on all ports. This can take some time. • If you do know the serial port that the TROLL Net Hub is plugged into, then select it to reduce the search time.
3. After all of the TROLLs have been found, the wizard will activate the OK button (the check mark). Click OK. 4. You will be prompted to select one of the TROLLs as the “Pump Well TROLL”. This TROLL will be used as the reference for step times and drawdown calculations. Click OK. 5. You will be prompted to connect to the TROLLs that were found. If you click Yes, the TROLLs will be connected and become active.
Chapter 3 Software Features The Virtual HERMIT screen has five tabs across the top that activate different views of the pump test information. The views are as follows: • Summary—general information and functions for adding Level TROLL instruments and exporting data. • Real-Time—shows the real-time readings of the connected Level TROLL instruments. • Log Graph—shows a chart of the downloaded logged data. • Log Table—shows a tabular view of the logged data.
3.1 VIRTUAL HERMIT CONTROL PANEL The bottom panel on the Virtual HERMIT screen displays the buttons for controlling the logging states of the connected Level TROLL instruments and for connecting/disconnecting from the network. The bottom panel also shows the current download activity and the current Draw Down values in the units of measure chosen for the Level/Depth parameter.
3.2.2 Real-Time Tab (View Level TROLL Readings) When connected, the real-time view will show the current readings from all of the connected Level TROLL instruments in one screen. The Depth and the Level values are shown on the real-time screen. This can help operators ensure that the Level TROLL instruments are still under water as the water level drops.
3.2.3 Log Graph Tab (Graphical View of Downloaded Data) This view shows a graph of the logged data for all the downloaded log files. The data is always displayed, even if no active connection exists, because this view shows logged data that has been downloaded into the Win-Situ working directory. (Note: Not real pump test data.
3.2.4 Virtual HERMIT Log Table (Tabular View of Logged Data) The log table view will show the logged data in tabular format. The user has the option of selecting the time units for the data rows. The actual time stamps of the logged data files are not used for this window since each Level TROLL might have logged data at different times. The first time value is determined by the first logged data point of all TROLLs. For TROLLs that do not have a matching logged record, the last known value is displayed.
3.2.5 Notes Tab The notes view allows the user to enter, edit, and delete notes regarding the pump test. For example, you may want to record the pumping rate here, rather than on paper. Notes added to this window are saved to the configuration file on the computer’s hard drive. These are different from log notes written into the Level TROLL logs while they run.
3.3 LEVEL TROLL VIEW FEATURES Like the Virtual HERMIT screen, the TROLL view has tabs that enable different views of the Level TROLL information. The views are as follows: • • • • • Real-Time—shows the real-time readings of the connected TROLL. Log Graph—shows a chart of the downloaded logged data. Log Table—shows a tabular view of the logged data. Log Notes—shows actions and status of the individual Level TROLL Device Info—displays general information and control functions for the specific TROLL.
3.3.2 Real-Time Tab Shows the real-time readings for the selected Level TROLL instrument.
3.3.3 Log Graph Tab Shows a graph of the logged data for the selected TROLL instrument.
3.3.4 Log Table Tab Shows a table of the logged data for the selected Level TROLL instrument. The times shown are the actual time stamps of the logged data for this Level TROLL.
3.3.5 Log Notes Tab Shows device specific notes for the selected Level TROLL instrument.
3.3.6 Device Info Tab Shows device specific information and some control functions for the selected Level TROLL instrument.
Chapter 4 Communications Select the Virtual HERMIT on the tree in the left pane and select the “Summary” tab in the right pane. If you do not have an open communication session (not connected) then click the “Connect” button. Communication Connect When you click the “Connect” button, the software will attempt to establish communication with each of the Level TROLL instruments that have been added to the Virtual HERMIT. The instruments can be on the same or different serial ports.
When you connect, the newest data will be downloaded automatically if a log is running on the Level TROLL. In some cases, the download may take a significant amount of time. The automatic downloads can be cancelled to speed up the connect process. Once connected, new data will be downloaded in the background. 4.1 CREATE A NEW PUMP TEST LOG If communications are established and there is no log running, you can create a new log on the connected Level TROLL instruments.
Later” option will allow you to configure the Level TROLL instruments and set the level references upon deployment. At the end of the log wizard, the log will be written to each of the connected Level TROLL instruments.
After the log configuration has been successfully programmed, the log status on the tree will update and the log summary will be shown in the Virtual HERMIT summary screen. This example uses the “Remind Me Later” level reference value. Updated log status Set pump well to get drawdown Log summary Level reminder Set pump well to get drawdown In this example, the Level Reference was not set in the Log Wizard.
4.2 SETTING LEVEL REFERENCE REMINDER When using the level reference reminder, the level reference can be set after the logs have been programmed into the Level TROLL instruments. To set a level reference on a TROLL that has the reminder flag set, select the TROLL on the tree and then click the “Set” button for the reference.
4.3 DATA EXPORT The Virtual HERMIT allows you to export logged data from one or more Level TROLLs to a single time-synchronized text file. To begin export of logged data, select the Virtual HERMIT on the left window pane, select the “Summary” tab and click the “Export Data” button. This will launch the export wizard that will walk you through the export options. At the end of the wizard, the data will be exported, and the exported file will be loaded into the tree on the left window pane for viewing.
4.4 DATA EXPORT WIZARD 4.4.1 Step 1—Choosing the File Name, Path, and Other Options The first screen as shown below, allows you to enter an export file name, select the export directory, and check or uncheck several options. Export File Name—if the file name you type in ends with the “.csv” extension, the file will be in comma separated value format. Any other file extension will result in a tab delimited formatted file.
• Export HERMIT notes—the notes added to the Virtual HERMIT screen, those notes saved on the hard drive (not the notes in the log files), will be exported to the text file. 4.4.2 Step 2—Set the Export Time Intervals, Resolve Time Stamps The second export wizard screen shown below allows you to choose the export time and data processing methods used to generate the export file.
values presented will be either “Last Logged Value” or an “Interpolated Value” as per the selection in the section “Resolve non-matching timestamps”. • Use Time Stamps from a TROLL Log as Reference—the time stamps of the logged records from the selected TROLL will be used. This ensures that the data records for that TROLL are the exact values that were logged.
4.4.4 Step 4—Define Column Headers The fourth export wizard screen allows the user to define the header on top of each column of data exported. This allows the columns of exported text data to be traced back to the original TROLL, log file, and site. 4.4.5 Step 5—Progress Screen The last export wizard screen shows the progress of the export process.
If the export file is locked by another application, for example Excel, then the software will generate an error message and you can try to re-export the data. Once the exported file is written to the hard drive, the wizard will close automatically and your exported file will be available in the Pump Test tree for viewing.
Chapter 5 Drawdown Calculations One of the key measurements in a pump test is the drawdown of the well for each pumping rate. During the test, the aquifer level changes shape—from having a flat water level to a cone-shaped level as the pump removes water from the aquifer. The drawdown is the difference between the water depth before pumping and the depth after pumping at a known pumping rate. 5.
After increasing the pumping rate for a period of time, a second plateau will emerge. This is the second step. These steps will also be apparent in the observation wells.
5.2 COMPUTING DRAWDOWN The Virtual HERMIT software will also compute the drawdown while the pump test is running. The drawdown is computed using the Level TROLL that is in the pumping well (not the observation wells), which was selected during the configuration of the HERMIT and Level TROLL instruments.
In the chart below, the white line indicates the drawdown for the entire test and the first step. These values are the same for step 1. The yellow line indicates the drawdown for the test, and step 2 (total drawdown minus step 1 drawdown).
