FLO, Continued
Additional
Features Additional features of the Totalflow System enabling its flexibility include the
following:
•
Programmable differential pressure zero cutoff
•
Programmable bi-level security codes to prevent unauthorized communication
and configuration of the
µ
FLO .
•
Automatic temperature compensation of electronic measurement circuitry
•
Automatic internal calibration of the RTD, with programmable bias adjustment
•
Quick, simple calibration procedures for IMV with steps outlined.
•
Real time clock providing a highly stable time base for the system
•
Battery operation period is determined by the size of battery, location of unit and
power consumption for communications. Totalflow Project Engineers can
configure your requirements and select the appropriate battery. Battery packs to
extend operation for longer periods without power are available.
•
Three available charging sources:
♦
External solar panel (standard)
♦
External AC/DC power
♦
External 24/12 VDC power
•
LCD (liquid crystal display) programmable to allow monitoring of the
µ
FLO
operations and any variable that has a Register (for example, displays voltage
level of batteries in
µ
FLO).
•
Rugged, aluminum, NEMA 4X enclosure, lockable to prevent internal access.
•
Optional ability to allow rapid data collection over communication link.
•
2 Communication ports are available on the
µ
FLO 2100767 Board: 1 dedicated
Local and 1 Remote Communication Interface.
Log Period Records
Each record has entries that contain the following information:
•
Average SP (static Pressure)
•
Average DP (differential pressure)
•
Average Ft (flow temperature)
•
Calculated Volume
Log Period Data
Entries
Log period data entries are made every 60 minutes by default. You may change
this period to one of 6 other choices (1,2,5,10,20,30,60). Choosing a log period of
less than 60 minutes will result in additional records being logged, thus requiring
more storage space to hold a full day’s data. The log period must never be less
than the volume calculation period.
Volume
Calculation
Period Entries
Volume Calculation period entries are made every 60 minutes by default. You may
change this period to one of 6 other choices (1,2,5,10,20,30,60). The volume
calculation period should never be greater than the log period and should be evenly
divisible into the log period.
Volume calculations are completed, following the top of the current period. (i.e. Top
of the hour, top of the minute)
