Calibrating the meter involves:
βͺ Comparing the dispensers stated amount dispensed to actual
amount dispensed.
βͺ Adjusting the K-Factor if accuracy is not within the required
tolerance.
NOTE: The K-Factor for each new dispenser is factory set and usually does
not need to be changed.
To test the meter accuracy:
Record the dispenserβs current density factor and set it to read out in kg
Density Factor (d5F).
β’ Test the meter accuracy using Calibration Test Fill Procedure - Method
1 or Calibration Test Fill Procedure - Method 2.
To calculate the meter K-Factor:
- Make sure that the dispenser is idle.
- Press and release the K-Factor button on the K-Factor board until
the K-Factor is displayed
Calculate the new K-Factor with the following formula:
πππ€ πΎ πΉπππ‘ππ = ππ₯ππ π‘πππ πΎ πΉπππ‘ππ Γ
πππ’π ππ’πππ‘ππ‘π¦
π·ππ ππππ¦ππ ππππ’ππ‘
πππ πππππππ:
πΈπ₯ππ π‘πππ πΎ πΉπππ‘ππ = 0.98
π·ππ ππππ¦ππ ππππ’ππ‘ = 5.80
πππ’π ππ’πππ‘ππ‘π¦ = 6.00ππ
πππ€ πΎ πΉπππ‘ππ = 0.98 Γ
6.00
5.80
= 1.0138(4ππ)
To input dispenser settings:
- Input the new meter K-factor.
- Set the density factor back to its original value. (dSF).
Method 1 of checking calibration involves filling a gas bottle and comparing
the read-out scale reading with the dispenser display reading.
