    Eagle Energy Meter and Solar ControlEagle 2 Thermal Energy Meter and Differential Temperature Control

    Connect to the Web:

    Connect the Eagle  Energy Meter and solar temperature controller to Wired Solar* for real-time Killowat hours and BTU monitoring to measure system performance and on-the-spot remote troubleshooting.

    Connect to Computer:
    An optional stand-alone PC based software package is also available; the Solar BTU Log can be installed in a local computer and connect to collector using using Adapter #SOLR-DA10 to monitor data log in graphical form and long-term data collection.

    Temperatures, pump activity and totalized Btus are transmitted in real-time to a computer or the web for a trend graph including calculated BTUs or kilowatts that are displayed in hours for remote or later viewing.

    *Wired Solar services are not included in price.

    Eagle 2 Energy Meter and Solar Control Features:
    Includes a full featured differential controller with an isolated serial
    interface which can be permanently connected to a PC for data logging and a Flow meter “plug and play” interface. The controller displays GPM and Kilo-watt hours of collected energy.

    The BTU calculations have bee carefully programmed to take into account the effects of Glycol-water mixtures. The Processors are permanently programmed to a specific percentage of Propylene Glycol present in the heat transfer solution from 0 % to 100%.

    Precision Matched sensors included to with in 0.2F which are essential for accurate BTU calculations. The matching was been tested and verified over the range of 80F to 210F in our precision temperature baths for each set of sensors supplied with each BTU / Controller. Connecting cables to both sensors have to also be matched with in 1.5 ohms of each other in the field. Cable length equivalency = 18Ga.>75 ‘, 20Ga.>35’. 22Ga.>20 feet

    Requires an IMC Data-Port Adapter that will allow interface to a standard computer’s serial RS232 port. The adapter can also accept a serial to USB converter to connect directly to portable computers that only have USB ports.

    Eagle adapter

    Port Adapter Model SOLR-DA10
    Send all data for graphical presentation to a computer using a PC Data RS-232 (non isolated) Port Adapter. It connects directly to the Eagle 2 WEB controller data port and permits serial PC communication at 2400 BAUD rate. Electronics are in the handle for long-distance transmission. Sample graph.

    If wireless operation is desired for short distances, Blue Tooth transceiver can also be connected. The rate at which the data is sent from the EAGLE solar controller is determined by a jumper in the controller.
