Are High Utility Costs Hurting Your
Bottom Line?
“The biggest issue is the
surging cost of energy,
which now makes up
30% of operating
costs for the average
company.”

Slide 12
Sometimes Less is More When It
Comes to PPL
The amount of pressure lost is a function of 3 factors:
•density of the fluid (f),
•velocity of the fluid (Vf)
•the amount obstruction (Kmeter) created by the flowmeter
PPL = Kmeter x f x (Vf)2
The following is a guideline for Kmeter, in order from
highest to lowest
