ENTER SPECIFIC GRAVITY VALUE (SPEC GR)
Basic Function (activated when mass units are selected)
The B3000 has two mass flow unit and two mass total unit choices (pounds and kilograms) When either pounds or kilograms
are chosen in either the RateUnt or TotlUnt parameters the Spec Gr entry parameter is activated
Mass readings in the B3000 are not temperature or pressure compensated so it is best to enter the specific gravity of the fluid
as close to the system running temperature as possible As liquids are essentially incompressible pressure compensation is
not necessary for liquids
Enter a Scale Factor Scale F
Extended Function
The scale factor is used to force a global span change For example, under operating conditions the display is reading a
consistent three percent below the expected values at all flow rates Rather than changing the K factor and linearization
parameters individually, the scale factor can be used to compensate for the three percent offset The scale factor would be set
to 1 03 to correct the readings The range of scale factors is from 0 10…5 00 The default scale factor is 1 00
At the Scale F prompt, press ENTER The first digit of the existing scale factor, if any, will begin to flash If the current selection
is correct, press ENTER to advance to the next parameter
If the current selection requires a change, use
▲ to increment the display digit until it matches the first digit of the new scale
factor Next press ► to advance to the next digit and using ▲ to increment the second display digit until it matches the
second digit of the new scale factor Repeat this step for the third digit Press ENTER to save the new scale factor
OTE: N If an out of range number is entered the display will flash Limit and refuse to allow the entry
Preset Total SetTotl
Extended Function
It is sometimes helpful to be able to set the totalizer to a predetermined number before starting a process The B3000 allows
this through the use of the set total menu entry The preset is capable of seven digits or up to 8,888,888
At the SetTotl prompt, press ENTER twice The first digit of the current preset total will begin to flash If the current selection is
correct, press ENTER to advance to the next parameter
If the current selection requires a change, use
▲ to increment the display digit until it matches the first digit of the required
preset Next press ► to advance to the next digit and using ▲ to increment the second display digit until it matches the
second digit of the preset Repeat this step until the preset is complete Press ENTER to save the new preset
OTE: N If an out of range number is entered the display will flash Limit and refuse to allow the entry
Low Flow Cutoff Cutoff
Extended Function
A low flow cutoff entry is provided to allow low flow rates (that can be present when pumps are off and valves are closed)
to be displayed as zero flow A typical value would be about five percent of the flow sensors maximum flow This setting is a
good compromise between suppression of noise and utilizing the full span of the flow sensor
The low flow cutoff is entered as an actual flow value For example if the maximum flow rate for the flow sensor was 100 gpm
the low flow cutoff values should be set for five percent of 100 gpm The entry would then be 5 0
At the Cutoff prompt, press ENTER The first digit of the current low flow cutoff will begin to flash If the current selection is
correct, press ENTER to advance to the next parameter
If the current selection requires a change, use
▲ to increment the display digit until it matches the first digit of the required
low flow cutoff value Next press ► to advance to the next digit and using ▲ to increment the second display digit until it
matches the second digit of the preset Repeat this step until the low flow cutoff is entered Press ENTER to save the new low
flow cutoff
OTE: N If an out of range number is entered the display will flash Limit and refuse to allow the entry
