Enter K Factor Unit
At the KFAC UNT prompt, press ENTER. The display indicates the current K factor unit. If the current selection is correct, press
ENTER to advance to the next parameter. For meters calibrated in gallons, use PUL/GAL; for meters calibrated in cubic meters,
use PUL/M3 (pulses per cubic meter); or any other unit choice. To change to an alternate K factor unit, use the arrow keys to
scroll to the desired K factor unit and press ENTER to save your choice.
OTE:N The K factor supplied with the meter or calculated from calibration data will be needed to complete the next step.
Enter Meter's K Factor
At the K FACTOR prompt, press ENTER. The most significant digit in the Kfactor will begin to flash. Using the UP arrow,
increment the display digit until it matches the meter’s K factor digit. If the current selection is correct, press the RIGHT arrow
to advance to the next digit. Repeat this process until all K factor digits have been entered. Press ENTER to save the K factor.
Scale Factor
At the SCALE F prompt, press ENTER. The current scale factor will begin to flash. If the current selection is correct, press
ENTER to advance to the next parameter. The scale factor is used to force a global change to all variables. For example, under
operating conditions the display is reading a consistent three percent below the expected values at all flow rates. Rather than
changing all 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 0.5…1.5. The default scale factor is 1.0.
Meter Type
At the METERTYP prompt, press ENTER. The current meter type will be displayed as LIQUID or GAS. If the current selection
is correct, press ENTER to advance to the next parameter. If GAS is selected, operating pressure and operating temperature
must be entered before advancing to the next parameter.
Damping Factor
At the DAMPING prompt, press ENTER. The current damping setting will begin to flash. If the current selection is correct,
press ENTER to advance to the next parameter. The damping factor is increased to enhance the stability of the flow readings.
Damping values are decreased to allow the flow meter to react faster to changing values of flow. This parameter can take on
any value between 0…99 with zero being the default.
Total Output Pulse
The pulse output (PULS OUT) parameter can be either enabled or disabled. When enabled this output generates 20 mS
duration pulse every time the least significant digit of the totalizer increments (20 Hz maximum). The amplitude of the pulse is
dependent on the voltage level of the supply connected to the pulse output and is limited to a maximum 30V DC.
Flow 4 mA Setting
When the loop powered option is ordered, the flow rate that corresponds to 4 mA must be set. If the current selection is
correct, press the RIGHT arrow to advance to the next parameter. If adjustment is required, press ENTER at the FLOW 4MA
prompt. The most significant digit will begin to flash. The RIGHT arrow moves the active digit one place to the right for each
press. The UP arrow increments the active digit one integer for each press. When the correct 4 mA flow rate has been entered,
press ENTER to store this value and move to the next parameter.
Flow 20 mA Setting
Follow the same programming procedure as the FLOW 4MA except for the flow rate setting. In this case, the maximum rate of
flow for the meter should be used.
4…20 mA Calibration
When ordered with a 4-20 mA output, this menu item allows the fine adjustment of the 4-20 mA output. The 4 mA setting is
typically between 35…50. To set the 4 mA value, connect an ammeter in series with the loop power supply. At the 4-20CAL
prompt, press ENTER. The display will show a steady NO indication. Press UP to change to a flashing YES display. Press ENTER
to access the 4 mA fine adjustment.
