flow_control symbol sometimes not correctly represented

[aschwuchow]

Describe the bug

When the geodata of a district heating grid is not set up with integers but with real geo coordinates (or small numbers in the range of 10^(-3), the components have to be scaled accordingly. Unfortunately for flow_contols, there is on line which doesn't scale with the rest (from junction 26 to 7 in screenshot).

Screenshots

• All grey colored lines are part of a component and not a pipe. Pipes are colored in yellow or black.

Python environment (please complete the following information):

• Windows 11 Pro (Version 22H2)
