Calculating the correction factor
Two different ways are described below to eliminate the existing deviation of a meter.
The reference quantity (“quantity dispensed”) should always be measured with an
appropriate measuring device.
•
Approved piston or bell prover
•
Approved gravimetric method
11.1 Calculation based default settings
Example:
Quantity dispensed: 5,000 liters
Quantity displayed: 4,990 liters
Correction factor k: 4,990 / 5,000 = 0,9980
11.2 Recalculation of an existing correction factor
Example:
Quantity dispensed: 5,000 litres
Quantity displayed: 5,015 litres
Correction factor k: 5,015 / 5,000 = 1,003
The existing correction factor would be for example: 0,9960
Calculation: 0,9960 x 1,003 = 0,9989
The new correction factor is 0,9989.
Viscosity of 440 mPas
Factor k about 1,0000
