Badger Meter Model IOG - Manual (Page 17)

NOTE: N Mass readings in the ER-500 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
Enter a Scale Factor (Scale F)
Extended Function
The scale factor Scale F is used to force a global span change For example, under operating conditions the display is
reading a consistent 3% 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 3% offset The scale factor would be set to
1 03 to correct the readings The range of scale factors is from 0 10 to 5 00 The default scale factor is 1 00
At the scale factor Scale F prompt, press the ENTER button once The first digit of the existing scale factor, if any, begins to
flash If the current selection is correct, press the ENTER button to advance to the next parameter
If the current selection requires a change, use the
▲ arrow button, increment the display digit until it matches the first
digit of the new scale factor Next press the ► arrow button to advance to the next digit and using the ▲ arrow button,
increment the second display digit until it matches the second digit of the new scale factor Repeat this step for the third
digit Press the ENTER button once to save the new scale factor
NOTE: N If an out of range number is entered the display flashes Limit and refuses 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 ER-500
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 preset total SetTotl prompt, press the ENTER button twice The first digit of the current preset total begins to flash
If the current selection is correct, press the ENTER button to advance to the next parameter
If the current selection requires a change, use the
▲ arrow button, increment the display digit until it matches the first
digit of the desired preset Next press the ► arrow button to advance to the next digit and using the ▲ arrow button,
increment the second display digit until it matches the second digit of the preset Repeat this step until the preset is
complete Press the ENTER button once to save the new preset
NOTE: N If an out of range number is entered the display flashes Limit and refuses to allow the entry
Low Flow Cutoff (Cutoff)
Extended Function
A low flow cut-off 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 5% 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 5% of 100 GPM The entry would then be 5 0
At the low flow cut-off Cutoff prompt, press the ENTER button once The first digit of the current low flow cut-off begins
to flash If the current selection is correct, press the ENTER button to advance to the next parameter
If the current selection requires a change, use the
▲ arrow button, increment the display digit until it matches the first
digit of the desired low flow cut-off value Next press the ► arrow button to advance to the next digit and using the ▲
arrow button, increment the second display digit until it matches the second digit of the preset Repeat this step until the
low flow cut-off is entered Press the ENTER button once to save the new low flow cut-off
NOTE: N If an out of range number is entered the display flashes Limit and refuses to allow the entry
