FB1100 Single-Run Explosion-Proof Flow Computer for Gas
The cost-effective FB1100 Explosion-Proof Flow Computer measures and monitors gas flow for a single differential pressure meter run.
As well as bringing a new level of measurement confidence, this low-power device can operate independently without external power, for up to one year, making the FB1100 model an ideal replacement for chart recorders. This simple to configure and easy to use device is designed for metering applications where flow control is not required. However, it has the ability to use a single pulse output (DO) for driving an odorizer. The FB1100 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.
