LI-COR - Solar Radiation Sensor
About 200 €
Li-COR LI200SZ - silicon photovoltaic detector
-Current output, which is directly proportional to solar radiation
-Calibrated against an Eppley Precision Spectral Pyranometer (PSP) under
natural daylight conditions in units of watts per square meter (W m-2)
-Under most conditions of natural daylight, the error is < 5% (2).
-Output - Typically 90 µA per 1000 W m-2
Carlo Gavazzi - Energy Meter
Type EM21 72D
Main Outputs:
• Currents (A);
• Voltages (V);
• Apparent power (VA);
• Active power (W);
• Reactive power (var).

Energy Meters
Brunata – Flow Sensor Technology
• Michael Faraday’s physical
law about induction
• Water is the conductor
• This
principle
allows
for
measuring range better than
1000:1
Brunata – Components of a Heat Meter
• Flow sensor
• 2 temperature sensors
• Calculator with display
Brunata – Calculation of Heat Energy
E – Energy consumed in a period of time;
V – Water volume passing through the meter in same period;
– Average temperature difference between flow and return in
the system;
k – Correction factor for heat enthalpy and the volume mass at
the temperature measured.

Output file
• The data acquired by all these devices will be
processed every minute into a string buffer and
after 10 minutes the last 10 buffered strings will be
updated into a FTP file trough the Internet. To
create this string, the application will also read the
cRIO-9074 board date and time to complete all the
required parameters.
