Supercompressibilty Calculated or Fixed
This parameter is used to set the mode for
supercompressibility calculations. If it is set
to 0, then a new supercompressibility value
will be calculated each time the process
executes. If set to 1, the unit will use the
value set in the Fixed Supercompressibility
Value parameter for calculations. The
Default value is
0. (Calculated)
Fixed Supercompressibility Value
If supercompressibility is Fixed, this
parameter should be set to the desired fixed
value. If supercompressibility is Calculated,
any value entered will be ignored. The
Default is
1 .
Time HHMMSS (Hours, Minutes,
Seconds)
This is the current military time in the unit. It
is updated on each process scan.
Uncorrected Pulse Out Enable/Disable
Uncorrected pulses can be sent to an external
device by enabling the Pulse Output Channel.
The Uncorrected Pulse Output - CF per Pulse
parameter, determines the rate at which pulses
are generated. An optional relay is required
for the pulse output. To enable Relay #4 for
pulse output, enter a value of
35.2 . Enter -1
to disable. The Default value is -1 . (Disable)
Uncorr Pulse Output - CF per Pulse
This parameter should reflect the value of the
uncorrected pulse output from the station to
an external device. For example, if each
output pulse represents 1000 cubic feet, then
this parameter should be set to 1000. The
Default is
1000 .
Uncorrected Volume
The uncorrected index represents the total
index volume registered by the station. When
changing this number, you will normally enter
the number that appears on the mechanical
index attached to the station. The Default
value is
0
.
Uncorrected Volume & Flow Multiplier
This multiplier specifies the output value for
uncorrected volume and flow. For example,
if the device is to measure flow in thousands
of cubic feet (MCF), select Thousands
(1000's) of units from the pick list. The
Default value is
1000 .
Ten Thousands (10,000's) of units 10000
Thousands (1000's) of units
1000
Hundreds (100's) of units 100
Tens (10's) of units 10
Single (1's) units 1
Wake Up Interval (seconds)
This parameter specifies the time (in seconds)
that the unit will wake up, execute the station
processes and perform all calculations.
Because the setting of this parameter directly
affects battery life, care should be exercised
to ensure that this item is set to the longest
interval possible for satisfactory operation.
The default values are as follow:
Battery or Solar unit
600 seconds - (Use if the unit powers up and
down and the Wake up on pulse parameter
(EFC only) is set to 0). The unit will wake up
every 10 minutes to execute the station
processes and calculate a new flow rate.
3600 seconds - (Use if the Wake up on pulse
parameter is not 0 to allow for history
recording - EFC’s only).
AC or Solar units
0
seconds - (Use if the unit is to be powered
up at all times). Calculations will be
performed on each process scan
(approximately every 3.5 seconds).
Wake Up On Pulse - event driven (EFC)
If this parameter is greater than 0, the EFC
will wake-up on the specified number of
pulses (meter revolutions). During wake-up,
pressure, temperature, and the rest of the
analog channels are sampled, and the unit
executes the processes and run calculations.
