i-Credit 511 is a single-phase, two-element smart meter with independent recording of multiple loads for enhanced tariff flexibility.

The modular design incorporates the latest cellular communications technologies to ensure reliable data transfer, making it the ideal solution for AMI applications.

The meter supports remote firmware upgrade, allowing metering and communications features and functionality to be updated in the field. This enhances flexibility, and makes the utility’s investment future-proof.

i-Credit 511 is an integrated part of Secure’s Liberty Online advanced metering solution.
