FB2100 Single-Run Field Mount Flow Computer for Gas and Liquids
The FB2100 Flow Computer is a cost-effective, low-power, field-mount device that measures and monitors gas and liquids flow for a differential pressure or linear meter run.
It is designed for simple configuration and ease of use and is an ideal solution for metering applications where control is not required. The FB2100 model 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. To ensure safety, the FB2100 model can also be equipped with optional FBxWifi™ that allows field personnel to configure the flow computer and retrieve data from outside of the hazardous area. The FB2100 Flow Computer is part of Emerson's next-generation FB Series measurement and control platform that offers a common set of configuration tools, including FBxConnect™, to expedite setup and facilitate commonly performed tasks.
