Total Installed Cost ComparisonTotal Installed Cost Comparison Annubar APTs require
less material– Small size, less weight– 24” Annubar < 45 lbs.*
Total installed costs are lower for Annubar Flowmeters, including:– Shipping costs– Labor time and cost– Lifting equipment– Less Straight Piping Needed
*For 150# Flanged version ~70lbs, Pak-lok ~45lbs as shown with transmitter

1 leak = $184/year in wasted pump energy
Energy to compress fluid escaping through leak is wasted and costs electricity$$
