To correct these types of errors we can modify the pulses per litre factor programmed in the
instrument.
Example - Shortage of volume
If we have a converter which specifies a k factor = 1.985, and when we check the volume of
a batch, we find that instead of having 100 litres as programmed, we have 105 litres (5%
more), we must apply the following correction:
F
k
= k factor (original pulses per litre)
= 1.985
V
= Expected Volume
= 100
Vr
= Real Volume
= 105
F
k
n = New k factor
= ? (1.887)

Change of units of measurement
In some cases we need to change the measurement units, for example, instead of working
in litres we need to work in kilograms. In this case we will need to know the density of the
liquid (
ρ
).
To change from litres to kg we must divide the pulse per litre factor by the density of the
liquid to obtain the new factor for programming the CIP II. For example, if the liquid has a
density of 0.9 kg/litre, the meter gives us 200 pulses per litre and we must count in kg, we
will program the CIP II using 222.222 as the new pulses per litre factor to be able to count
directly in kg.
