The well tape relies on fluid conductivity to determine the presence of water. An audible signal and visible LED light activate when the probe contacts water. This water level meter incorporates a sensitivity adjustment to prevent false triggering.
The 9 Volt DC alkaline battery will last up to 8 hours of continuous detecting. When not in use, the meter should be stored with the switch in the OFF position. If the meter will be stored for more than three months, the battery should be removed.
The sensitivity of the probe can be adjusted to prevent false triggering while still detecting water levels.

Is eradicating Great Lakes sea lamprey an “impossible dream?” Researchers say no
The sea lamprey’s days in the Great Lakes could be numbered.
That’s according to one researcher who took one of the first scientific looks at the possibility of sea lamprey eradication in the Great Lakes.
So, can you remove enough sea lamprey to make them disappear?
“Well the answer is we already have,” said Michael Jones, emeritus professor of fisheries and wildlife at Michigan State University. “Then there’s the obvious question: Why are they still here?”
While multiple gaps in current management techniques, like sea lamprey poisons called lampricides, could account for sea lamprey’s persistence in the Great Lakes, new technology could help sea lamprey managers eliminate inaccessible populations.Read More
The Shasta crayfish and signal crayfish are two similar looking arthropods on two very different ecological trajectories. As one spreads in abundance, originating in the Pacific Northwest and spreading throughout the world, the other has been reduced to a handful of remaining populations spread throughout one river and its tributaries.
Pacifastacus leniusculus - the signal crayfish - has met few obstacles in its widely successful expansion from the Pacific Northwest southward in California and Nevada, as well as Europe and Japan. By some expert accounts, it has reached invader status. And while invasive species are rarely good for the surrounding food webs, it’s Pacifastacus fortis - the Shasta crayfish - that’s suffered the most at the signal crayfish’s fortune.Read More
What might the Maine Aquaculture Innovation Center’ s (MAIC) buoy offer that other governments and university monitoring equipment lack? The center doesn’t have MicroCAT recorders or autonomous acoustic sensing gliders. It’s not deploying hundred-thousand-dollar oceanographic mooring lines gathering massive amounts of data.
So what can MAIC’s three-foot prototype buoy offer that others can’t? It’s easy to clean and costs very little.
“One of the big issues for putting anything in the water is biofouling,” said Josh Girgis, an engineer at MAIC based at the University of Maine’s Darling Marine Center (DMC). “If you put a sensor in, you can only expect it to work until something starts growing on it.Read More
