1, 5 Drain valves
2, 4 Inlet valves
3 Equalizing valve
6, 7 Vent valves on the measuring device
A, B Shut-off valves
1. Fill vessel to a level above the lower tap.
2. Fill measuring system with fluid.
Open A and B (shutoff valves).
Fill the negative pressure piping to the level of the condensate trap.
3. Vent the measuring device.
Open 2 and 4 (introduce fluid).
Close 4 (low-pressure side).
Open 3 (balance high-pressure and low-pressure side).
Open 6 briefly, then close it again (fill the measuring device completely with fluid
and remove air).
4. Set measuring point to operation.
Close 3 (separate high-pressure side and low-pressure side).
Open 4 (connect low-pressure side).
Now:
B and 6 are closed.
A is open.
