Updating Positional Tags for Biomet Data

Updating Positional Tags for Biomet Data

Version 8.0.0 of the LI-7500RS/LI-7500A/LI-7200RS/LI-7200 gas analyzer embedded software implemented a new identifier for Biomet data.  The identifier is a set of three digits that indicates the horizontal position (h), vertical position (v), and replicate number (r) at that position.  This naming protocol is based on the protocol for the AmeriFlux and ICOS networks (http://ameriflux.lbl.gov/data/aboutdata/data-variables/).  This information is stored by the LI-7550 in the biomet.metadata file for use with EddyPro® Software.  In the Sutron datalogger, there is a communications tag…

Wiring an RM Young Sonic Anemometer to a LI-COR EC System

Wiring an RM Young Sonic Anemometer to a LI-COR EC System

The RM Young 81000 sonic anemometer is one of the many sonic anemometers that can be used with a LI-COR EC system. Since the RM Young provides a junction box, wiring it to the LI-7550 is straight forward. The Analog Input/output cable (Part Number 392-10109) provided with the LI-7550 spare parts kit can be used instead of the Auxiliary Sensor Interface Unit. You can wire the bare lead ends directly to the junction box of the RM Young 81000 and…

Control Over Drought

Control Over Drought

Water is one of the most precious natural resources—and one that we often take for granted. But droughts are common and they’ve proven time and time again that we don’t know enough about the water cycle. That is why the Chinese Ecosystem Research Network (CERN) selected LI-COR eddy covariance systems to measure evapotranspiration across the country. Recently the Water and Waste Digest interviewed Dave Johnson, Senior Product Manager, to learn more about how the Chinese Ecosystem Research Network is using evapotranspiration to…

Fresh Data Every Morning

Fresh Data Every Morning

There’s nothing like a fresh download of data to get your day started. The Internet of things has made it possible for you to download your data automatically from your Eddy Covariance measurement system directly to your computer. Using wired Internet, or cellular or satellite communications, your measurement system can be remotely accessed from the comfort of your office or home. After you have set up remote access, here is a quick tip that can help you reduce…

SDI-12 Sensor Inputs with the Sutron Datalogger

SDI-12 Sensor Inputs with the Sutron Datalogger

The Sutron 9210B datalogger records biomet data in LI-COR eddy covariance systems.  In addition to measuring analog voltage inputs, it can also record data transmitted via the SDI-12 communications protocol from up to ten sensors.  Programming a sensor with SDI-12 output requires an extra step—the sensor must be given a unique address.  In this example, we connect a Stevens Hydra Probe II soil moisture/temperature sensor to the datalogger.
1. Power on the datalogger, and connect to it with the…
