Electronic Volume Converters

The Corus Evo+ is an electronic volume converter for commercial and industrial natural gas applications.

By measuring temperature and temperature from the gas flow in the meter, the Corus Evo+ provides accurate data with a Corrected Pulse Output. The Corus EVO+ is the fundamental component of a reliable gas solution for Commercial and Industrial customers.

Featuring:

• MID compliant EN12405-1 2018 optional Class A accuracy to EN12405-2 2012
• ATEX and IEC approved for hazardous area Zone 0 or 1
• Up to 15 years autonomy
• IP66 enclosure
• Gas temperature range of -25C up to +70C
• Pressure range of 0.8 – 5, 2 – 10, 7 – 35, and 14 – 70 bar
• Battery operated up to 10 years
• Optional modules: 4 to 20 Ma, RS232, RS485
• Weighs 2kg

ELCORlite is a single-channel gas volume corrector powered by lithium batteries.

Low frequency pulse inputs used to connect to the gas meter.
Pressure measurement is provided by the latest type of digital pressure transducer ELGAS EDT 125, which can be
installed to the device as internal or external.

Very wide measuring ranges (e.g. 80 – 2000 kPa) make it easier for the user to use the device in various types
of measurements.
Temperature measurement is again performed by ELGAS product namely the EDT 124 temperature transducer which is a new digital converter with a semiconductor sensing element.
The local user interface is realized by LCD graphic display with backlight, which allows in combination with up to
6-button keyboard display of all information, including stored data and also offers the possibility to change the settings of basic parameters.
Alternatively, the device can be supplied with a segment display, which allows a permanent display of the measured
quantities.
Communication with the corrector can be realized using a metallic RS485/RS232 serial interface.

An optical interface (according to IEC-1107 / IEC 62056-21) is used for local setting or local data reading

ELCORlite is powered by batteries with a high capacity, ensuring the operation of the device for more than
10 years. The modem is powered by its own lithium battery which depending on the selected modem, allows
the modem to operate for a period of time up to 20 years (in LTE-NB networks). Optionally, ELCORlite can be
powered from an external source, both the corrector and the modem (PS-E and PS-M1 power supplies).
