The flowcom made by systec is a device that is used to compensate the errors made by flowmeters. It is known that many mediums just like steam, oil or gas change their properties by heating them up or setting them under pressure. Those parametres are then calculated with the metered values to get a result that is as accurate as possible. And that is how the flowcom works: Die Ermittlung von Dichten und Enthalpien in Gasen und anderen Wärmeträgermedien im druck- und temperaturvariablen Bereichen ist meist problematisch da alle Modellgleichungen fehlerbehaftet sind und nur befriedigende Ergebnisse liefern. Especially with if the medium is under high pressure or a low temperature, the equations that you normally calculate with are practically unusable. For not using those equations, the flowcom comes with a table that contains lots of medium states and their relevant pressure and temperature values. If the table is not yet enough for your use, it is easily possible for you to create your own tables and if no values are known for your medium, the flowcom is also able to calculate with the equations. If you should need the flowcom at two measuring points at once, it is no problem: the flowcom can work with two metering points at once.
