The Corus Gas Volume Converter is an electronic volume converter dedicated to commercial and industrial applications. It converts the actual volume measured by the gas meter to reference conditions. Thus, CORUS is a key element in the whole Itron chain, from the meter to billing data. CORUS uses the measured working values of volume, pressure and temperature to provide:

• the converted volume
• the conversion factor
• the compressibility factor (several formulas available)
• a large database
• pulse retransmission

The system is built in an IP65 enclosure, for wall or meter mounting. Thanks to its accurate piezo-resistive pressure sensor and its 4 wires PT1000 temperature probe, CORUS provides an accurate conversion on the whole temperature range.

The non-metrological firmware can be updated in the field without stopping operations and without breaking the metrological seals (MID). Its large integrated database can be customised to fit the customers’ needs. Recorded data and number of records can be freely set.

The converter is the base element of a complete and extremely flexible system, perfectly adaptable to the customer’s requirements:

• Consumption, pressure, temperature monitoring through its large database for billing purposes
• Monitoring functions for gas stations
• Remote reading solutions through PSTN, GSM, GPRS or TCP/IP with several integrated communication protocols: IEC-62056-21 (IEC-61107), MODBUS RTU, IDOM
