Designed for use with In-Situ water quality and water level sensors, the In-Situ Con TROLL PRO Process Monitor provides real-time data and integrates easily with SCADA and PLC systems. The Con TROLL PRO also operates as a standalone unit for field monitoring applications.

The In-Situ Con TROLL PRO Process Monitor can display and report multiple parameters from up to two In-Situ sensors, including the RDO PRO; Level TROLL 200, 300, 500, and 700; and Aqua TROLL 100, 200 and 400. Users can quickly access and download data via Bluetooth wireless technology and a RuggedReader handheld PC or laptop.

The In-Situ Con TROLL PRO Process Monitor automatically measures & compensates for barometric pressure and ambient temperature. When used in combination with the RDO PRO and Aqua TROLL instrument, the Con TROLL PRO will log salinity compensated DO readings, thus achieving the most accurate results.

AC models are available with or without logging and include two low-voltage relays and two high-voltage relays. Relays can be used to trigger alarms, warning lights, pumps, gates, or other process control devices. DC models offer logging, two low-voltage relays, and flexible power supply options. Both AC and DC units offer power saving modes, Modbus/RS485 communication protocol, automatic sensor recognition, and two isolated 4-20 mA current loops.

Restoring Native Brook Trout in North Carolina

The North Carolina Wildlife Resources Commission ’s Inland Fisheries Division has been working to restore brook trout in the state. Coldwater research coordinator Jacob Rash, who works with the brook trout team technicians on this project, spoke to EM about the work. “In North Carolina, brook trout are our only native trout species,” explains Mr. Rash. “With that come biological and ecological considerations as well as cultural importance. A lot of folks here grew up fishing for brook trout with their relatives, so it's an important species that we work to try to conserve. We've done quite a bit of work to figure out where those brook trout populations are and what they are, in terms of genetics.

Robotic Fish May Reduce Live Fish Testing Near Hydroelectric Plants

Each year in Germany, as many as 450,000 living fish undergo live animal experiments to test how fish-friendly hydroelectric power plants in the country are. The idea is to discover how readily the fish can move through hydroelectric turbine installations in order to ultimately reduce mortality rates. Of course, subjecting live fish to a potentially deadly test to save others is a bitter irony. And it's one that a team of scientists from the RETERO research project hopes to eventually mitigate with a robotic fish for testing. EM corresponded with Olivier Cleynen and Stefan Hoerner from the University of Magdeburg about the complex flow conditions that set the parameters for the project.

Mobile HAB Lab, Citizen Scientists Building Awareness

News stories about dogs getting sick from harmful algal blooms (HABs) in lakes have caused worry among members of the public this summer more than once. But Regional Science Consortium (RSC) Executive Director Dr. Jeanette Schnars and a dedicated team are bringing awareness about HABs to the public with the Mobile HAB Lab. “We just launched the HAB Citizen Scientists program this year,” explains Dr. Schnars. “It helps us work with people, especially people who spend time at marinas frequently, that are out there all season long.” The season for boaters at Presque Isle, where RSC is located, starts in mid-May and usually continues through the beginning or middle of October.
