Integral thermowell available in all sizes
Innovative upstream slot for comprehensive averaging
T-shaped sensor creates large stagnation zones on backside to reduce noise

4. T-Shape Improves Accuracy and Reduces Plugging
Provides a more accurate measurement than traditional APTs

6. Rosemount Annubar Flowmeters
Pak-Lok
Patented compression design firmly secures the Annubar sensor to the opposite wall of the pipe. Rated up to 600# ANSI.
Flanged With Opposite Side Support
Meets the requirement of high pressure applications. Available up to 2500# ANSI.
Flange-Lok
Combines Pak-Lok compression mechanism with a mounting flange
Flo-Tap
Can be hot-tapped without interruption of the flow. Easily removed for cleaning or line pigging. Available up to 600# ANSI.

7. Flo-tap Mounting Can Be Used in Applications with Dirty Fluids
Can be easily removed for cleaning or line pigging and re-installed

8. Annubar APT has Lowest Permanent Pressure Loss of Any Primary Element
On this one, we need to take out the name optima and change it to the new Annubar
Minimizes Pumping and Compression Costs

10. Total 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

13. Pak-lok Mounting Installs in 3 Easy Steps

14. Integrated Flowmeters Reduce Installation and Maintenance Time and Cost
Annubar Installation
Traditional Orifice Plate Installation
Assembly is factory leak tested
Few leak points at time of installation
Leak points at every fitting
Factory Checked
1 leak = $184/year in wasted pump energy
Energy to compress fluid escaping through leak is wasted and costs electricity$$
