HyQuest Solutions’ single tipping bucke flow gauges TB0.5L and TB1L are used for measuring water seepage coming out of a pipe or a drain. In both models, 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.

TB0.5L and TB1L are perfectly suitable for flow measurements in water carrying sediments or iron hydroxide deposition. Made of plastics 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.

Lake Malawi: A Treasure to Protect

Lake Malawi (also known as Lake Nyasa and Lake Niassa) doubles as a Rift Valley Lake and one of the seven African Great Lakes. Due to its unique biodiversity, it’s a great place to conduct limnological studies. Harvey Bootsma is a professor for the School of Freshwater Sciences at the University of Wisconsin-Milwaukee and has had an interest in limnology ever since he was a kid. Bootsma fondly recalls summer vacations to Georgian Bay, Ontario, “I probably spent as much time in the water as I did out of it.” He continues, "I remember telling myself, ‘I’m going to get a job where I can stay here all the time.’” While Harvey didn’t end up working on Georgian Bay, he was offered a job working on Lake Malawi. He continued working there while completing his Ph.D.

Microbes and Human Health: Aquatic Microbial Communities May Hold Clues about How Deadly Pathogens Spread

Aquatic ecosystems are incredibly complex, with many different biotic and abiotic factors constantly interacting. Microbial communities are a key part of aquatic ecosystems, involved in the constant flow of energy and recycling of organic matter, according to Science Direct .  The true scope of microbial community impacts on aquatic ecosystems is still not entirely understood. Eric Benbow, a professor of community ecology at Michigan State University, is exploring how microbial communities and pathogens may be negatively impacting human health, and how a changing climate could worsen this problem.  How Do Pathogens Arise? Benbow, along with his students and colleagues, are studying a realm of community ecology that is still relatively unknown.
