MICRO-C1 Electronic Volume Corrector

MICRO-C1 is a compact, high accuracy, single stream electronic volume corrector intended for high performance industrial gas metering with or without remote telemetry.

This industry-leading EVC introduces superior measurement stability, accuracy, and reliability. It provides the full set of calculations normally found in flow computers. Calculations include nine compressibility methods, namely AGA 8-DC92, AGA 8 gross methods 1 & 2, NX 19, MGERG, SGERG methods 1, 2, 3, 4, AGA 5 energy & mass methods, ISO 6976 heating value method, and AGA-7 meter correction.

With its local communication ports and I/O channels, it can be easily interfaced with a wide variety of field devices and systems. Its advanced remote communication capabilities allow realization of large scale centralized metering systems. Newly added 4G interface provides superior remote communication performance.

As well as meeting local metering needs, MICRO-C1 also provides a complete solution for gas utilities seeking fast, efficient, and cost-effective network operation and management.
