  • Determining the Right Cable Length and Output for a Sensor

    If you’re monitoring a bridge or automating a machine, a high precision sensor is a great solution, but it’s no good if the output signal can’t reach the data logger. Depending on what you need to measure and what environment you’re in, determining how long your cable must run can be crucial. High precision sensors offer three common output types: analog, digital and ...

  • Case study - Discharge measurement deep within a cave

    Research is currently being conducted in the Hessenhau cave, located in southern Germany. The cave is the deepest known within the Swabian Alps at 144m (472 ft) and has a stream running through it that connects it to other caves within the area. Discharge measurements were taken in different parts of the cave with the OTT MF pro electromagnetic current meter. Reaching the bottom of the cave ...

  • Accuracy, precision, usability, and cost of portable silver test methods for ceramic filter factories

    Locally manufactured ceramic water filters are one effective household drinking water treatment technology. During manufacturing, silver nanoparticles or silver nitrate are applied to prevent microbiological growth within the filter and increase bacterial removal efficacy. Currently, there is no recommendation for manufacturers to test silver concentrations of application solutions or filtered ...

  • Improved Water Management Propels Growth of Ontario Cheese Maker

    Like all farmers, the Van Bergeijk family works hard from ‘sun up to sun down’ to run their farm in southwestern Ontario. Everything in the dairy farming operation is interconnected. They grow corn on their 325 hectare farm to feed 400 dairy cows. The cows produce 11,000 litres of milk a year. That milk is used to make the prize-winning Mountainoak ...

  • The Scientific Story of the Souris: Could the 2011 Flood Happen Again?

    If the current wet climate state of the Souris River Basin continues during the next 10 years, there is a 2 percent chance another extreme flood, similar to that of 2011, will occur, according to a recent report by the U.S. Geological Survey and North Dakota State Water Commission. These and other findings about past and future flooding of the ...

  • Unstable flow structure around partially buried objects on a simulated river bed

    The unsteady flow characteristics around two partially buried objects, a short cylinder and a truncated cone, were examined with a three-dimensional, non-hydrostatic hydrodynamic model under similar steady unidirectional currents with flow Reynolds numbers, Re, of 86,061 and 76,209, respectively. Model simulations were conducted with the two objects partially buried in a simulated ...

  • Investigating the management of unaccounted for water for Lilongwe Water Board, Malawi

    Lilongwe Water Board (LWB) is currently unable to meet Lilongwe City's water demand as evidenced by low supply coverage (65%) and intermittent water supply in the city. One of the major challenges is high levels of unaccounted for water (UFW) reported at 37% (2012), higher than the recommended 23% for developing countries. This study, done in Lilongwe City (Areas 15, 18 and 28), investigated ...
