The video below shows how the Tactical Flow Meter works and what advantages it has over conventional Thermal Mass Flowmeters.

Our Datalog Configuration Benefits

The Tactical Flow Meter boasts a power fail tolerant datalog storage system that is a significant improvement over conventional "SD Card" file storage/file management systems.

While both our datalog storage system and a conventional "SD Card" storage systems utilize flash storage technology our storage system concatenates each event or data at the end of the file using a simple pointer system where the pointers stored in EEPROM and the data is stored sequentially after the last event.

If the power goes out in the middle of a storage event in a conventional "SD Card" system and the entire file can be lost.  If a power outage occurs during the middle of writing an event in our storage system the worst case is corruption of a single event at most.

Again, SD Card technology can lose an entire file while the Tactical Flow Meter datalog storage system would only lose a single event.
