Warning!
The seal is not allowed to press on the process isolating diaphragm as this could affect the
measurement result.

Note!
•
Due to the orientation of the Deltabar S, there may be a shift in the measured value, i.e. when
the container is empty, the measured value does not display zero. You can correct this zero point
shift either via the "zero" key on the electronic insert, or on the outside of the device or via the
on-site display.

•For FMD77 and FMD78, please refer to Section 2.3 "Installation instructions for devices with
diaphragm seals", Page 6.
•The FMD77 must only be insulated up to a certain height.
•General recommendations for routing the impulse piping can be found in DIN 19210
"Methods for measurement of fluid flow; differential piping for flow measurement devices" or
the corresponding national or international standards.
•Using a three-valve or five-valve manifold allows for easy commissioning, installation and
maintenance without interrupting the process.
•When routing the impulse piping outdoors, ensure that sufficient anti-freeze protection is used,
e.g. by using pipe heat tracing.
•Install the impulse piping with a monotonic gradient of at least 10%.
•Do not clean or touch diaphragm seals with hard or pointed objects.
•To ensure optimal readability of the on-site display, it is possible to rotate the housing up to
380°.
