Installation instructions
• Due to the orientation of the Deltabar S, there may be a shift in the measured value, i.e.
when the container is empty or partially full, the measured value does not display zero. You
can correct this zero point shift using the "Zero" key on the electronic insert or externally
on the device or via the onsite display.
36, Section 6.2.1 "Position of the operating
37, Section 6.2.3 "Function of the operating elements – onsite display
65, Section 7.5 "Position adjustment"..
• For FMD77 and FMD78, please refer to Section 4.3.4 "Installation instructions for devices
with diaphragm seals (FMD78)",
• General recommendations for routing the pressure 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-way or five-way valve manifold allows for easy commissioning, installation
and maintenance without interrupting the process.
• When routing the pressure piping outdoors, ensure that sufficient antifreeze protection is
used, e.g. by using pipe heat tracing.
• Install the pressure piping with a monotonic gradient of at least 10%.
• To ensure optimal readability of the onsite display, it is possible to rotate the housing up
to 380°.
29, Section 4.3.9 "Rotating the housing".
• Hauser offers a mounting bracket for installing on pipes or walls.
26, Section 4.3.7 "Wall and pipe-mounting (optional)".
