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.

Birds, Fish and Shifting Sediment; How Lake Erie Buoys Measure It All

Since its population bottomed out, the federally-endangered Piping Plover in the Great Lakes has made a comeback for the ages.  A population that once measured approximately 17 pairs and rebounded, hitting 76 pairs in 2017. The same year that count was made, the plovers had also returned to Gull Point, a nesting location that hadn’t been used in more than 60 years.   In an effort to understand some of the conditions that have allowed this species to return to its habitat, researchers have directed their attention toward a curious instrument for help. A buoy that floats off the coast of Presque Isle State Park , near where Gull Point is located.

Much remains unknown about sharks. The Cal State Shark Lab wants to change that

Thirty years ago, white shark sightings near California’s beaches almost never happened. For Chris Lowe, who was a graduate student at California State University’s Shark Lab at the time, spying a dorsal fin from one of the ocean’s top predators was very rare. Prior to the mid-90’s, an expansive commercial fishing operation and the loss of marine animals decimated white shark populations. If their food wasn’t being hunted, sharks were getting caught in gill nets. At that point, they would be killed anyways before getting brought to the market to be sold. Then in 1994, California residents approved propositions that banned gillnets in state waters and enacted protections for the white shark.

REASON Project Puts Water Quality Instrumentation in Dams

Where and how to monitor water quality is always a challenge, particularly in complex aquatic ecosystems. The new REASON Project from a team at Clarkson University is working to demonstrate the utility of using water quality instrumentation in dams on major rivers in the Great Lakes system. Clarkson University Professor of Biology Michael Twiss spoke with EM about the new approach their team is taking at the Moses-Saunders Power Dam across the St. Lawrence River and the benefits the development of smart infrastructure such as this might offer. “The upper St. Lawrence River is defined as that which leaves Lake Ontario and is just upstream from the city of Montreal,” explains Dr. Twiss.
