Note!
• Before calibrating the device, the impulse piping must be cleaned and filled with fluid. See the
following table.
Valves Meaning Installation
1 Fill container to a level above the lower tap.
P01-PMD55xxx-11-xx-xx-xx-009
Closed container
IDeltabar M
II Three-valve manifold
III Separator
1, 2 Drain valves
2, 4 Inlet valves
3 Equalizing valve
6, 7 Vent valve on Deltabar M
A, B Shut-off valve
2 Fill measuring system with fluid.
Close 3. Shut off high-pressure side
from low-pressure side.
Open A and B. Open shut-off valves.
3 Vent high-pressure side (empty low-pressure side if
necessary).
Open 2 and 4. Introduce fluid on high-
pressure side.
Open 6 and 7 briefly, then
close them again.
Fill high-pressure side
completely with fluid and
remove air.
4 Set measuring point in operation.
Now
– 3, 6 and 7 are closed.
– 2, 4, A and B are open.
5 Carry out calibration according to one of the following
methods:
• "in pressure" - with reference pressure ( ä 84)
• "in pressure" - without reference pressure ( ä 60)
• "in heigth" - with reference pressure ( ä 90)
• "in height" - without reference pressure ( ä 90)
