The NexSens OEM line of data loggers are designed for installations in larger enclosures where external 12VDC power is available. The OEM data loggers deliver unmatched sensor interface and data collection in a compact package. Options are available for standalone, cellular, radio, Ethernet, and satellite telemetry. Each data logger simultaneously supports 8 analog inputs & 4 digital inputs for multi-sensor data logging capability.

The OEM data logger arrives ready for long-term deployment. All electronics are housed in a rugged, NEMA 4X enclosure. Polymer-coated circuit boards, sealed connectors, corrosion-resistant stainless steel hardware, and built-in lightning protection ensure reliable performance in the harshest conditions. All sensors are cabled through Sealcon gland fittings to ensure protection from the elements.

NexSens iChart Software is a Windows-based program for interfacing both locally (direct-connect) and remotely (through telemetry) to a data logger or network of data loggers. The iChart Setup Device Wizard includes built-in drivers and a step-by-step interface for setting up and configuring remote monitoring sensors and systems. When connected, the user can quickly configure sample & log intervals, upload data, or troubleshoot communications.

Pulse Flow Brings Colorado River Delta Big Benefits

A few years ago, a pulse flow was released into the Colorado River Delta per Minute 319 of the U.S.-Mexico Water Treaty of 1944. The flow began March 23, 2014 and ended on May 18, 2014, pushing around 130 million cubic meters of water downstream. A few months after that, this magazine checked in with some of the scientists involved in monitoring the effects of the pulse flow. Investigators told us they had deployed more than 100 piezometers to study groundwater levels. Flow trackers were giving them discharge data and measurements on salinity were being gathered with conductivity probes. For gauging the impacts to waterfowl, the researchers were using stereos to send out mating calls while listening for responses. But there was so much more data collection underway than we knew.

Lake Erie Infographic

It’s pretty easy to find a Lake Erie infographic these days. And that makes sense, because the water body is an incredibly important one. We laid out some of the dynamics that make it that way in our most recent print edition, published in fall 2016 . Those include its shallow depth, a factor that makes it one of the most productive Great Lakes both for fish and algae. Another is the population surrounding Lake Erie. Did you know that the Erie watershed has nearly 12 million people? That makes it the most populated area of the region! In our latest edition, the Lake Erie infographic serves as a nice background for readers who may be unfamiliar with the lake. It also helps to introduce our coverage of Lake Erie’s western basin.

White Bear Lake Stands Out In Study Of Twin Cities Lakes

Following water level declines in lakes around the Twin Cities area of Minnesota, scientists at the U.S. Geological Survey were interested in identifying the cause. What they found along with that was a large degree of variability between the lakes, based on geology, elevation and land use. That there was such variation isn’t too surprising, as Mother Nature is far from neat in laying things out. But the sheer size and scope of the study has a nice way of underscoring just how different individual lakes can be from one another even if they sit nearby. The effort, looking at 96 different lakes around Minneapolis and St. Paul, Minn., found wide variation in water levels over time. Some lakes gained in water levels while others nearby saw them decline.
