1.3 PRODUCT OVERVIEW
The FloBoss 407 is a microprocessor-based flow computer (see Figure 1-1) that provides functions
required for gas flow measurement and custody transfer in accordance with standards such as AGA
1985 or 1992 orifice metering. More generally, the unit provides on-site functionality for applications
where there is a need for remote monitoring, measurement, data archival, communications, and control.
The design allows the user to configure the FloBoss 407 for specific applications including those
requiring calculations, logic, and sequencing control using function sequence tables, as well as PID
loop control.
The FloBoss 407 is available in two versions based on the type of approval: the standard hazardous
area version, and the Measurement (Industry) Canada custody transfer version, which includes
hazardous area approval. These versions have a number of differences both in firmware and hardware.
Both of these versions are further subdivided by the type of orifice metering calculations (either AGA
1992 or AGA 1985) included in the firmware.
