Schlumberger Diver – Download Data
At several locations, Mini-Divers have been installed as a redundant water level sensors to the existing gas purge systems. With a 5-minute data logging setting, the internal memory of the Divers will be full in ~83 days. There is no memory wrap feature and the Divers must be stopped/started in order to erase existing data. Data for the Mini-Diver and BaroDiver must be downloaded individually.
- Connect the threaded end of the USB interface cable to the Baro-Diver
- Open Diver-Office
Wire Weight
The basic parts of a wire weight gage include a drum wrapped with a single layer of cable, and a weight attached to the end of the cable. A readable disc, graduated in tenths and hundredths of a foot is attached to the side of the drum. A Veeder counter, reading in whole feet is also included. One complete turn of the drum represents one foot of vertical movement of the weight. To take a reading of stage, perform the following:
- Open the wire weight gauge house
- Move the checkbar forward so it rests in position under the weight, if not already in position
- While grasping the drum crank handle, disengage the pawl and lower the weight until it touches, but not fully rests on the check bar
- Read the interval at the pointer on the graduated disc (the numbered hash marks correspond to tenths and five-hundredths of a foot graduations and the small hash marks correspond to one-hundredth foot increments)
- If the check-bar value does not match, perform the following inspections:
- Make sure the check-bar is set correctly
- Check that the cable is wrapped on the drum properly and the threading sheave is positioned properly, directly above the wrap on the drum
- Make sure the graduated disc is not slipping (caused by loose clutch screws)
- Check the Veeder counter for proper operation (occasionally the counter is not synchronized with the graduated disc and will not turn over to the next whole foot in synchronization with the disc
- If the check-bar value is satisfactory, slide the bar back and slowly lower the weight to the water surface (the weight should only touch the water surface enough to form a distinctive “V” shape on the water surface)
- Read the Veeder counter and disc as previously described
- Record the stage height on the front sheet
- Wind in the weight.
- Confirm the check bar elevation and reengage the pawl before closing and locking the wire weight gauge enclosure

WaterLOG H-350XL/H-500XL – Transfer Data
Stream data downloaded from equipment in the field should ideally be transferred immediately from temporary media (e.g., USB key) to a folder on the laptop, and should be stored in the SiteMonthDayYear format (e.g., 800a080615).
- Locate appropriate file on laptop and transfer to station folder on network drive (e.g., Q:\STATIONS\TL\800A\2015\Misc)
- Open Hydstra and select from the menu tree: Programs by Function > Hydstra/TS – Time Series > Hydstra Data Management > HYDMWB – Data Managers Workbench.
- Press the Open folder icon or select File > Open
- In the Open Time Series Sites dialog box that opens, enter the site number in general format (e.g., 800) and click the Lookup Site button
- Select the specific site (e.g., 800A) that appears in the dialog box and then press OK
- Press OK in the Open Time Series dialog box
- Single-click the site icon that has an A at the end (e.g., 800A A) and the select File > Copy
- In the Select Work File dialog box that opens, Select B as the New DataSource and then press OK; a new file icon is placed on the workbench (e.g., 800A B)
- Select File > Import Data and navigate to appropriate file on the network drive, as described in step 1, and then press Open
- Press Finish in the Import Data dialog box and close the event log that appears in Hydstra Explorer; a new file icon is placed on the workbench (e.g., 800A C)
- Drag the C file to the B file and release
- In the dialog box, select the Resolve Overlaps: Split blocks if necessary, preserving the C file radio button and press OK
- Double-click the B file to open the Work File dialog box (the end date of the 232.00 variable should be modified to match the date and time of the site visit)
- Double-click variable 232.00, which will open the High-Resolution data set
- Most of the time, Gap<MaxGap (ignored) will be displayed between the previous data set and the data set most recently imported
- To eliminate this gap, select the block of data immediately below this status and select Split
- In the Split Block dialog box, add five minutes to Split Time (e.g., 10:50:00_07/20/2015 becomes 10:55:00_07/20/2015) and press OK; this will create an additional block of time
- Select the new block and the one immediately above it (this should be the one that has the Gap<MaxGap (ignored) status) by shift-clicking both
- Select Fill Gaps and from the dialog box that opens, select the Extend Backwards (add a new point to the start of the second block) radio button and 1 Good Unedited Data from the Inserted Quality dropdown; press OK
- A new block is created which spans the existing blocks; both the new block and the block below now display Yes in the Modified column
- Close the dialog box and press Yes to save your changes and then close the Work File dialog box
- Finally, drag the B file to the A file and select the Merge (preserve B File data if duplicates) radio button, making sure the Delete B File option is checked
- Press OK and close event log that appears in Hydstra Explorer
WaterLOG H-350XL/H-500XL – Download Data
Gage height and discharge data are periodically transferred from the unit in the form of a .NEW file. After being copied to the appropriate media, the .NEW file is deleted, thereby reducing file size for subsequent downloads. Should problems arise in downloading this file, a longer term record (.WRP file) is stored on the unit and can be accessed in a similar manner. Unlike the .NEW file, the .WRP file is only deleted at the end of each water year.
The processes described below is applicable to several types of transfer media, including USB keys or PCMCIA (Flashdisk) cards
