FB1100 Single-Run Explosion-Proof Flow Computer for Natural Gas | Emerson
The FB1100 is a cost-effective, low-power explosion-proof flow computer that measures and monitors gas flow for a single differential pressure meter run.
As well as bringing a new level of measurement confidence, it is able to run independently without external power, for up to one year, making the FB1100 an ideal replacement for chart recorders. Designed for simple configuration and ease of use, the cost effective FB1100 flow computer is focused on metering applications where control is not required. The FB1100 is part of Emerson's new flow computer family that delivers a convenient approach to remote oil and gas sites by addressing challenges to power, safety, and measurement accuracy.
