FLO Computer Hardware
The Totalflow®
µ
FLO 6200 Computers are housed in a lightweight single compartment aluminum case.
It’s components are:
•
Aluminum enclosure
• µ
FLO 2100767 Board
•
Integral Multivariable Transducer
•
Liquid Crystal Display (LCD)
•
Resistive Temperature Detector (RTD)
•
Battery Compartment Shelf (Model 6213 only)
•
Communication Area(Model 6213 only)
•
Charger or Solar Panel(Model 6213 only)
Enclosure
The enclosure consists of hinged-door box. The door provides a watertight,
corrosion resistant seal between the outside elements and the
µ
FLO
components. It is NEMA 4X rated. Opening the door’s latch allows access to
electronics and Integral Multivariable Transducer (IMV) components.
µ
FLO 2100767
Board
The
µ
FLO 2100767 Board is mounted directly on the Integral Multivariable
Transducer (IMV). All user connections to the board are mounted directly on the
face of the board. The
µ
FLO 2100767 Board uses a low power processor
running at 11.0592 MHz with Data stored in 512K SRAM. RAM memory has
lithium backup battery. The applications programs are stored in 512K Flash, the
flash loader is stored in 512 K PROM, and Registry and Configuration files are
stored in 32K E
2
PROM. Other circuitry processes the inputs from the IMV and
provides interfaces to the LCD and the PCCU. Remote communications are
handled by the
µ
FLO Communications Connector J3 (See Figure 1–6, Item #1
and Table 1-1).
Integral
Multivariable
Transducer (IMV)
The IMV contains circuitry for processing all measurements and provides the
primary measurement capability for the
µ
FLO (See Figure 1-6). The unit is
designed to provide EMI/RFI protection of the low level signals, and to protect
the circuitry from other environmental effects.
Because the IMV is characterized over temperature at the factory the unit is not
field repairable. All repairs should be done at an authorized Totalflow depot
service center or returned to the factory. The IMV is characterized over
temperature so that any changes occurring in the IMV or in the electronics can
be compensated.
Resistive
Temperature
Detector (RTD)
An optional 100-ohm platinum RTD measures real-time flowing temperature of
the gas. The standard RTD is provided with a 10-foot cable. Other lengths of
cable are available upon request.
Battery
Compartment Shelf
The battery compartment shelf (6213 only) will house various optional battery
packs that are available for the
µ
FLO; from 8 ampere hours up to 26 ampere
hours. Installation of the battery is discussed in detail in Chapter 4,
Maintenance & Troubleshooting.
