7200-101 Flow Module – High Frequency Noise Reduction

7200-101 Flow Module – High Frequency Noise Reduction

In some situations, the 7200-101 Flow Module may emit high frequency noise through its exhaust port. This may occur if the motor drive of the Flow Module is ramped up to maintain the flow rate as pressure drops in the flow path.

Inline filters that clog up over time may cause a significant motor drive increase, especially if the inline filter is not replaced before the motor drive reaches its maximum at 100%.

The Power of FV2200

The Power of FV2200

Leaf Area Index (LAI) measurements, such as those taken by the LAI-2000 or the LAI-2200/C, can be used to determine treatment effects, crop progression, and seasonal variation, to name a few parameters.

The process of obtaining LAI measurements can be very simple.  To generate a value for LAI, take a series of Above and Below canopy readings, repeating as many times as needed to develop statistical robustness.   The process of interpreting them, however, can be more complex.

FV2200 has many…

Upgrading the Wheels on the LI-6800 Travel Case

Upgrading the Wheels on the LI-6800 Travel Case

The LI-6800 travel case is a vast improvement over the case offered with the LI-6400/XT. One of the major changes in the case is that it has wheels, making it very easy to transport the instrument. For most users, the stock wheels on the case will perform well and last a long time. However, for users like the Field Application Scientists at LI-COR who put many more miles on the case than a typical user, the stock wheels just don’t…

Using a Cradlepoint Modem with LI-COR Eddy Covariance Systems

Using a Cradlepoint Modem with LI-COR Eddy Covariance Systems

LI-COR Eddy Covariance systems can be used with a variety of modems and M2M devices for remote communication. LI-COR provides Sierra Wireless modems for remote communication. However, there are a variety of other devices that can be used. Please refer to our technical note on cellular communications for Eddy covariance.

Cradlepoint manufactures various kinds of M2M/IoT and In-Vehicle Routers that can be used for this purpose. These modems are not officially supported or supplied by LI-COR, but here are…

Changes to LI-8100A Wireless Communication

Changes to LI-8100A Wireless Communication

Wireless communication is an excellent way to use the LI-8100A Automated Soil Gas Flux System in the field to start and stop logging, and view the data in real time. For wireless communication, the system has always relied on a peer-to-peer connection using a Cisco wireless card inserted into one of the PC card slots in the LI-8100A Analyzer Control Unit. Apple iOS devices, like the Windows Mobile and PALM devices before them, were able to easily connect using peer-to-peer networking.

However,…
