Easily upgrade to the most accurate andreliable single run gas flow computerIntroductionThis guide is designed for typical installations only. Maintenance must be performedby personnel knowledgeable of the ABB Totalflow® μFLO G5 flow computer, theintegral multivariable transducer (IMV), and the theory of natural gas electronic flowmeasurement. Maintenance personnel must also be knowledgeable of local andnational codes as they apply to hazardous areas, communication wiring, andelectrical wiring.CAUTION – Equipment damage. The μFLO G5 flow computer operatingtemperature range differs from the μFLO G4 . The μFLO G5 is rated forambient temperatures between -40 °F and +158 °F (-40 °C and +70 °C).Do not upgrade to the μFLO G5 if the ambient temperature range fallsoutside of this range.PurposeThis guide provides simple instructions and information for upgrading an originalμFLO (referred to as the μFLO (G3) for clarification purposes) or a μFLO G4 to aμFLO G5 flow computer.Application guideG5 flow computersμFLO G5 (microFLO G5 )Upgrade kit
