The HyQuest Solutions TB1L tipping bucket flow gauge is used for measuring water seepage coming out of a pipe or a drain. The bucket is connected to its own dual reed switch effectively enabling redundant data acquisition in two distinct data loggers, or providing data to two devices (e.g. a data logger and a counting display), etc.

The TB1L is perfectly suitable for flow measurements in water carrying sediments or iron hydroxide deposition. Made of platsics and coated steel, these devices are both robust and fast and easy to clean.

The bucket tips when it is filled to maximum. The magnet integrated into the bucket rearside slides along the reed switch mounted in the flow gauge’s frame. The magnetic field forces a contact closure in the reed switch. The latter can be recorded by one or two connected data loggers. The number of tips per time unit is a measure of the flow rate.

Not So Quiet Polar Night: Arctic Creatures Found to be Active During Dark Part of the Year

Most people need little more than a comfortable pillow, a blanket, and a dark room to drift off into a multi-hour snooze. Many researchers assumed that once plunged into darkness for about half the year during the polar night, most polar creatures would do the same: fall asleep and take a big nap for as long as the darkness lasted. But Jon Cohen, associate professor of marine sciences, school of marine science and policy, in the College of Earth, Ocean, and the Environment at the University of Delaware, wondered if that was true. Despite the technical challenges of monitoring biota in very low light conditions, Cohen and his team were determined to find out if krill, copepods, and other creatures were dozing off in the dark or seeking out prey, light, and each other.

Orange Stream Dreams: Monitoring Acid Mine Drainage and Watershed Health

Not many young people pondering careers come up with the words “acid mine drainage.” But Jen Bowman, Director of Environmental Programs at the Voinovich School at Ohio University, could not help but be fascinated by what she saw during her days as an Ohio University student collecting field samples. “My interest in acid mine drainage, and how it affects watersheds, goes way back to my undergraduate days,” she explains. “We saw firsthand how streams could be impacted by drainage from abandoned mines. Sometimes streams had such severe problems they turned orange. It was hard not to be struck by that. I was drawn in to the many associated challenges, keeping watersheds clean, and improving stream health.
