### 6.1.22. Special components

- Pressure differential gauge and pressure signal are used to measure the calculation pressure differential between any two points of the system.
To measure pressure difference between selected points of the system, place a pressure gauge at one point of the pipe-run, and a pressure signal at the other point. Then click the symbol on the pressure gauge and drag it to the point where the pressure signal is placed. The two components will be linked together:
