You're wondering whether our software accounts for pressure loss in equipment added as a custom element, such as a flow sensor.
No, our software does not allow for manually entering performance data such as pressure loss. If you add custom equipment, you will need to consult the manufacturer's literature and account for pressure loss manually when designing your system.
While we do not allow manual entry of pressure loss in custom equipment, you can adjust the Critical Analysis manually once everything is sized and you've run the Critical Analysis schedule. We leave the Critical Analysis open as a table for easy editing for this exact purpose.
