Honeywell EC 350 Volume Corrector

Honeywell’s EC 350 Gas Volume Corrector is intended to simplify and optimize custody transfer and industrial measurement. This new electronic corrector platform offers best-in-class accuracy, expanded memory, advanced diagnostics, and integrated cellular communications. The ER 350 also reduces maintenance requirements and is intuitive and simple to use. 

The EC 350 line provides many operational advantages. These flexible devices have a common look and feel. And utilize state-of-the-art technology such as reverse flow capability.
