FB2100 Single-Run Field Mount Flow Computer for Natural Gas
The FB2100 is a cost-effective low-power field mount flow computer that measures and monitors gas flow for a differential pressure or linear meter run.
Designed for simple configuration and ease of use, the cost effective FB2100 flow computer focuses on metering applications where control is not required. The FB2100 provides a full audit trail, including enhanced history, alarm and event logs. The I/O options can be as simple as a single discrete output (DO) for driving an odorizer or can be expanded to give two user configurable analog (AI or AO) channels and two user configurable discrete (DI, DO or PI) channels.
