Bell & Gossett SystemSyzer

System Syzer is an HVAC tool that helps with piping system design. The application is based on the original plastic wheel calculator by designed by Gil Carlson of Bell & Gossett. It was first introduced in 1963 and has since been distributed to well over a hundred thousand engineers and tradesmen.The tool is made up several different calculators. There is a calculator for friction loss and velocity through pipe based on your fluid conditions. Use it to determine the relationship between fluid temperature, system flow and heat/cooling load. There is a Cv tool that can help in multiple ways. We have also bundled the Circuit Setter® / Triple Duty Valve calculator that is very handy for balance contractors. Use it during design to help predetermine valve settings and out in the field to determine flow through the valves based on pressure drop readings.

Using circuit setter tool, wants to autofill my email addresses in the numerical value fields. Every time. Infuriating.

Easier to carry than the original syzer wheel.

What is Cv value can anyone explain it thank you

This app has the same internal calculation error as the iOS verson has had for over a year. Enter user-defined viscousity and Re goes to infinity for pressure drop calcs. This is a fantastic rough calc tool, but I wish someone would fix the bugs.

I dont know whats going on here, but this once amazingly reliable app is having accuracy issues. Using the Circuit Setter tool, I have seen three different phones calculate three different GPMS using all the same data. I am now talking to others in the balancing industry at other companies, they are finding the same issues. BEWARE! Check against the wheel, if you have one.

I love it. Not sure why others are having accuracy issues, mine always line up with the wheel. Possibly they're using the wrong circuit setter size or type? App doesn't have all of them.

Does what it should, bonus load calculator
