The Fulcrum3D Sodar is different to most Sodar devices available on the market. The main features are listed below: – Specifically designed for use in complex terrain. – Accurate and highly validated by independent consultants. – Fixed beam angles for greater consistency between sites. – Full raw data capture allows historic data to be reprocessed
The Fulcrum3D Sodar provides data on wind conditions including wind speed, wind direction, wind speed standard deviation and inflow angle (related to vertical wind speed).
Sodar stands for Sonic Detection And Ranging. It works by sending out a sound pulse and recording the reflections scattered back off the atmosphere. The change is sound frequency of the reflection is converted into wind conditions and the time it takes to detect the returned sound indicates the height of the measurement.
This error is related to the zero offset type A. Normally this zero offset is present when the inner dome has a different temperature from the cold junctions of the sensor. Practically this is always the case when there is a clear sky. Because of the low effective sky temperature (<0 °C) the earth surface
Not directly. The output signal from this pyranometer is in milivolts and the input channels on the EOL Zenith ranges from 0-5 volts. You therefore need an amplifier for this pyranometer. The amplifier we supply is called AMPVAR.
This depends on the type of barometer. If you use the e.g. Setra M276 sensor (output in voltage) you need to increase the cable section from 0,5mm2 to 2.5 mm2 to avoid signal loss. Unlike most other barometers the frequency output from the K611P barometer however ensures signal integrity from the top of the met mast
All the most common sensors (anemometers, wind vanes, etc.) used in wind & solar resource assessment are compatible with the EOL Zenith.

To ground the EOL Zenith®, connect one end of the copper ground wire (usually yellow-green color) to the data logger GND terminal and the other end to an independent grounding spike. If the enclosure is metallic you must also connect the enclosure to the ground wire, to do so, all metallic enclosures have a connection
Usually solar power systems for the EOL Zenith consist of a solar panel, a charge controller and a battery. Important! Always connect the battery terminals directly to the BAT + and – on the data logger. Do not connect the LOAD+ and LOAD- to the data logger. The reason we recommend this is to avoid
In addition to dimensioning the solar power supply system correctly, it is important to orientate the solar panels appropriately for maximizing the energy production during the season with less sun energy. In general the solar panel should be facing GEOGRAPHICAL SOUTH in the Northern hemisphere and GEOGRAPHICAL NORTH in the Southern hemisphere. And as a
