Introduction
This guide is designed for typical installations only. Maintenance must be performed
by personnel knowledgeable of the ABB Totalflow
integral multivariable transducer (IMV), and the theory of natural gas electronic flow
measurement. Maintenance personnel must also be knowledgeable of local and
national codes as they apply to hazardous areas, communication wiring, and
electrical wiring.
CAUTION – Equipment damage. The µFLO
temperature range differs from the µFLO
ambient temperatures between -40 °F and +158 °F (-40 °C and +70 °C).
Do not upgrade to the µFLO
outside of this range.
Purpose
This guide provides simple instructions and information for upgrading an original
