Honeywell – EC250 Electronic Volume Corrector

Part of Honeywell's EC250 Volume Corrector range. The EC250 Electronic Volume Corrector (EVC) is built for gas distribution companies and commercial and industrial operators who need confidence in every cubic foot measured. Designed for direct mounting on rotary gas meters, the EC250 PTZ gas volume corrector delivers accurate, repeatable volume correction to improve fair billing, reliable custody transfer, and clear operational visibility.By combining a compact footprint, universal compatibility with leading rotary meters, and secure connectivity options, the EC250 helps operators protect revenue and reduce lost or unaccounted for gas. At the same time, it simplifies installation, commissioning, and ongoing maintenance—so teams can spend less time in the field and more time focused on safer and efficient network operation.

Key Benefits

Accurate, Reliable Volume Correction: Corrects measured gas volume using pressure and temperature inputs, with redundant volume sensing to reduce the risk of lost and unaccounted for gas and support reliable billing and custody transfer.

Universal Direct Mounting: Designed for direct installation on rotary gas meters, enabling fast deployment across mixed installed bases with minimal installation effort.

Built-In Meter Health Monitoring: Integrated differential pressure measurement and logging provide continuous insight into meter performance, eliminating the need for frequent site visits and manual DP testing.

24/7 Connectivity: AMR ready and compatible with leading systems such as Itron, Aclara, and Sensus, with optional Honeywell CloudLink 5G cellular connectivity for secure, automated data transmission.

Cybersecurity by Design: Developed to meet modern security requirements, including ANSI/ISA 62443 and IEC 62443 compliance, ISASecure® SDLA certification, and TLS encryption to protect critical measurement data.
