The OTT MF pro velocity sensor has a range of 0 to 6.09 m/s (0 to 20 ft/s).
The Both the OTT MF pro velocity sensor and OTT MF pro velocity & depth sensor have a minimum conductivity requirement of 10 uS/cm. If the conductivity of the water is less than that, the electromagnetic field will not operate properly.
As long as the sensor knob is submerged, the velocity sensor should work properly. You will need to do follow the 0.9xVmax flow measurement method if you are not measuring at different depths and averaging velocity. This method calculates flow based on 90% of the fastest velocity and is the recommended method when the depth is less than 12.7 cm (5 in.) or when the velocity is not stable.

USGS Streamflow Gages Track Ever-Changing Nature Of Nation’s Rivers
Rivers are a fundamental part of the American landscape, determining not only the geological features of the land, but also providing habitat for plants, animals and civilizations. Although rivers are a permanent part of the landscape, the rivers themselves are constantly changing, flowing at high or low levels, subtly changing course and affecting everything around them. Constantly monitoring the changes is very important, as the data influence flood predictions, show flood frequencies, indicate low-flow behavior, influence recreational pursuits as well as water management practices and can indicate potential improvements in engineering design. Few people know the temperament of constantly changing rivers as well as Tom Harris, Ohio data chief for the U.S.

Once-vacant village gathers baseline data on Southwest Alaska stream
The Kuskokwim River--the second-longest river in Alaska and the longest free-flowing river in the U.S.--winds through state's remote Southwest where isolation drives gas up to $7.50 a gallon. "Here in the Kuskokwim, this is what some people refer to as 'Real Alaska,'" said Dave Cannon, environmental director of the Native Village of Napaimute, which sits on the north bank of the river. "You could go to Anchorage and it would be just like any other big city. But you get out here--you can only get to where I'm at by airplane or boat." Napaimute played a historically important role in mining and fur trading in the region, but the village mostly vacated when those industries dwindled in the area.

Rounded pebbles give evidence of past flowing water on Mars
NASA's Curiosity rover has found pebbles that appear to have been rounded by streamflow, according to a release from University of California Davis. Experts say the finding represents the first on-site evidence of sustained flowing water on Mars. The rounded pebbles discovered are only known to form when transported through water over long distances. Their discovery supports theories that the red planet could once have supported life. The smooth rocks were found between the north rim of the planet’s Gale Crater and the base of Mount Sharp, a mountain inside the crater. Researchers say they chose Gale Crater for study because there was a sediment deposit there that typically requires water to form.
