Software & Firmware
FLOWPACK SOFTWARE — V 1.21 — 18FEB2013
Become an instant velocity-indexing pro! FlowPack allows you to generate easy to interpret Velocity-Index ratings. Promising to make your data reporting process a whole lot friendlier (and faster), FlowPack also provides a simple method to store flow, velocity, and stage measurements — all through one software program. FlowPack can produce comprehensive reports that assist you in making better, more informed decisions.
SONTEK-IQ SOFTWARE — V 4.1 - 08APR2024
The SonTek IQ Window-based software package contains an all in one package for interfacing with the SonTek IQ Standar, Plus and Pipe models. The software is used to interface, configure the system, visualize and export data.
Recent improvements include:
- Added user-configurable (manual) velocity cell sizes
- Increased sampling interval and duration range: 1 to 3600 seconds
- Improved performance in very shallow water (less than 15cm)
Other features include:
- Water level options, including the ability to use pressure data if vertical beam is too shallow or variable. Gives you more data in shallow and variable conditions when data might otherwise not be reported. Prevents data loss.
- Advanced user settings for working in difficult flow regimes. Gives you more flexibility to adapt to conditions at your particular site.
- File size limit on recorded data files. The IQ reports lots of data--you might want all those data but not in large file sizes that take long to download. Now, you can opt to limit file sizes for more bite-size downloads.
- Modbus output now includes the 40,000 registers. Some Modbus users will find this easier to integrate with their networks.
- When outputting total volume, now you can choose to reset the total volume after N samples. This is more convenient and allows higher-resolution data for those outputting data over analog signal that has to be set up with a maximum analog signal range.
SONTEK-IQ FIRMWARE — V 3.1 — 09SEP2021
SonTek-IQ firmware version 3.1 addresses:
- Fix for SDI-12 data logger interruptions
- Improved in-air pressure calibration routine
- Corrected ASCII “A” command response when the Sample Interval is not equal to the Sample Duration.
