Example 2 - Excess of volume

If we have a flowmeter body which specifies i/l = 1.985, and when we check the volume

of a batch, we find that instead of having 100 litres as programmed, we only have 105

litres (5% more) and we must apply the following correction:

i/l = Original Pulses per litre Factor = 1.985

V = Expected Volume = 100

Vr = Real Volume = 105

i/l n = New Pulses per litre Factor = ? (1.887)
