Write User Full Scale Value
The Write User Full Scale (UFS) feature adjusts the flow meter’s en-
gineering output range anywhere within 50% to 100% of the factory
full scale (FFS). This feature allows you to re-range the voltage or
current output of the meter to accommodate different flow rates.
To enter a new user full scale:
1. Verify the desired range is selected. Choose the Function Se-
lector and select Write User Full Scale.
2. In the Value to Write selector type in the desired setting in flow
units. (The program will automatically correct any out-of-range
settings.)
3. After entering the value, click the Go button. Check the User FS
indicator and confirm that the new User Full Scale value is correct.
Write K-Factor Value
The K-factor value is a multiplication factor applied to the output of
the flow meter. Use the K-factor setting to accommodate varying
flow profiles. This feature adjusts the meter’s output signal without
affecting the factory calibration curve (linearization). A K-factor
value of 1.0 means the output value is not affected and is the factory
default setting. You may enter any number from 0.5 to 5.0.
For example:
If you have an indicated value of 50 units and you know it should be
60 units, enter a K-factor of the ratio of the two or 60/50=1.2
To enter a new K-factor:
1. Verify the desired range is selected. Choose the Function Se-
lector and select Write K Factor Value.
2. In the Value to Write selector type in a number between 0.5 and
5.0. A value of 1.0 equals a K-factor of 1. (The program will
automatically correct any out-of-range settings.)
3. After entering the new value, click the Go button. Check the K-
Factor indicator and confirm that the new K-Factor value is correct.
Caution!
The flow meter must
not be reporting or
measuring gas flow
during adjustments.
