3.0 System Overview
3.1.4 Special Applications Using an SF-1020i Flowbench
Many SuperFlow flowbenches are used daily to measure airflow through cylinder heads, manifolds, throttle
bodies, carburetors and other components.
What can you measure on a SuperFlow SF-1020i flowbench? The answer is just about anything you can
mount on the bench. Some manufacturers use the bench as a Quality Control (QC) process to quantify
catalyst materials. Other applications include mufflers and air filters. The aerospace industry also uses the
benches to maintain QC on parts for various gas turbine components. Using PowerNet Flowbench Data
Acquisition and Control software provides an easy way to compare parts by Effective Flow Area (EFA). The
software can also be used to quantify cylinder heads and manifolds with a relatively new approach.
What is the largest diameter part tested on a SuperFlow bench? Over 18 inches in diameter and 6 feet tall.
The component is for a very large gas turbine that drives a stationary electrical power generator.
Odd applications? How about natural gas control valves that control the fuel for gigantic shipboard
engines? How large? A 10,000-hp valve is considered small.
Small applications? The smallest known application is used to set the idle opening in throttle bodies where
the target is 3.5 cfm at 25"H
