OTT MF pro Velocity & Depth Sensors
Questions & Answers
What method does the sensor use to determine speed?
The OTT MF pro velocity and depth sensor uses an electromagnetic method to determine velocity. A magnetic field around the sensor creates a voltage proportional to the flow velocity, which is then detected by the electrodes in the sensor and transmitted to the meter.
What is the purpose of the optional depth sensor?
During a discharge measurement, a typical user will read the water depth from wading rod markings. With a the integrated depth sensor, water depth can be measured automatically, reducing human error in the field and providing increased accuracy.

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.

Study suggests small dams have more negative effects than large dams

A recent study suggests that small dams may have a greater impact on rivers than large dams, as they divert more water away from rivers, according to a press release from the American Geophysical Union. Researchers from Oregon State University studied China’s Nu River, which is home to a variety of dams in the river main stem and its tributaries.  In total, 31 small dams were evaluated and compared to four large dams in the main river stem. The research team compared dam impacts to habitat loss, river channel lengths, land affected and landslide risks among 14 total factors.  They found small dams had a greater negative impact in nine out of 14 categories. Small dams, used to divert water to hydropower stations, had some of the most profound impacts on rivers.
