A true Windows application with its own help screens, the System Syzer program isn’t restricted to the physical size of the original plastic wheel version. It includes significantly more information and functions, such as:

• Expanded pipe size calculations through 48″ diameter
• Displays of Reynolds numbers, flow rates, relative roughness and friction factors, along with friction loss and velocity values
• A viscosity correction feature that allows the user to adjust for different water temperatures up to 350ºF and varying concentrations and temperatures of ethylene, propylene glycol and other fluids with known properties.
• A balance section with preset and gauge data for Circuit Setter, Large Circuit Setter and Triple Duty valves. The section also permits calculation adjustments based on fluid type and has a report generator to aid balancing contractors.
