1Defined as power on with screen on at 100% brightness, ADV sensor pinging 50% of the time, GPS off, and no sleep periods. Actual battery life will vary depending on FT2 settings, manner of use and brand of battery.
2Ideal conditions and settings. GPS data are intended for approximate georeferencing and site ID.
3Remove batteries from FlowTracker2 handheld if storage temperatures exceeds operating temperature of Alkaline and NiMH batteries as stipulated above.
Software & Firmware
FlowTracker2 Software - PC
Comprehensive tables and time series graphs allow you to visualize and QC data during analysis. Change SmartQC criteria and edit data—yet rest assured the original file will always remain untouched. FT2's open-source JSON file format is ready to be read into any organization's database, and is supported with direct import to Hydstra and WISKI.
FLOWTRACKER2 — V 2.0 — NOV2024
Graph, view, analyze, and edit data collected with the FlowTracker2 instrument, and generate reports using the Windows-based FlowTracker2 software. Station data as well as point measurements can be edited, yet the original data file will always be preserved. View beam checks and perform many other diagnostic and QC checks whose criteria can also be manipulated in software settings. Generate or edit template files in the office which can be uploaded to the FlowTracker instrument and used to save time in the field. Export data to *.CSV format or import the FlowTracker's open-souce JSON files directly to databases.
November 2024 improvements include:
- Added probe disconnect monitoring to prevent critical Handheld hardware failure. Updating the software on the handheld using the installation steps below will completely address this issue.
- Fixes a bug that caused chart drawing in the desktop software to freeze for certain files.
Recent updates also included:
Handheld Software
- Handheld keypad programming modification to prevent accidental and unintended keypad lockup. Recommended for all users.
- Handheld electronics revision resulting in an expected battery life of approximately 11 hours of continuous use under normal operating conditions.
- Improved work flow and display for under ice measurements
- Station number now included in title bar at each point measurement so you always know what station you are at and how many you’ve performed
- The maximum number of templates has been increased to 100 so you can store your entire agency’s site information for quick measurement set-up
Desktop Software
- The mean velocity calculation in the discharge summary is now based on Q/A (and not the measured mean of all stations)
- User can now enter manual temperature and salinity values in the supplemental data
- Additional valuable information has been added to the discharge summary: beam check plots, start/end time
- Improved software speed
FlowTracker2 software includes language support for English, Spanish, French, Portuguese, German, Italian, Russian, Chinese (traditional and simplified), Japanese, Korean, Polish, Catalan, Romanian and Greek. A built-in multi-language translator tool can be used to customize software for additional languages and regional terminology.
- Microsoft Windows 7 or newer
- 1GHz processor or better (2 GHz recommended)
- 2GB memory (4GB recommended)
- 500 MB available disk space (1GB recommended)
