3.1.2 Transport and Storage
Important
Only use the hoisting gear and auxiliaries (e.g. lifting straps) suitable for the weight to be
lifted. Max. load information can be found on the type plate of the hoisting gear. It is strongly
recommended to use the eye bolts supplied with the device only.
During OPTISONIC 7060 transport and storage operations, make sure that:
¾
The sealing surfaces of the flanges are protected with special caps
¾ The measuring device is firmly secures at all times
¾ Measures are taken to avoid mechanical damage
¾ Humidity and ambient temperature are within specified limits (see Section 2.2.4).
If the device is to be stored outside for more than one day, sealing surfaces of the flanges
and the interior of the meter body must be protected from corrosion, e.g. with Anticorit spray
(not required for stainless steel meter bodies). The same measure shall be taken if the
device is to be stored in dry condition, but for more than a week.
Note Due to natural temperature fluctuation in the course of a day, or if the measuring device is
transported to a place with different temperature and humidity, moisture will condense on
any material. Carbon steel surfaces may corrode if left unprotected.
3.2 Assembly
Generally, the installation arrangement is specified during the project planning phase, i.e.
before installation of the system. Nominal width, material and type of flange should therefore
be defined in accordance with the design of the existing plant. It is particularly important that
the internal diameters of the meter body and adjacent pipelines are identical.
Fixing bolts, nuts and flange seals used must be suited to the operational conditions, and
comply with legal regulations and relevant standards.
Note Any deviation from the planned design of the OPTISONIC 7060 and installation arrangement
shall be agreed with the supplier and documented prior to installing the measuring device.
Measuring location
• The OPTISONIC 7060 can be installed in customary straight inlet and outlet pipes. The
adjacent pipes must have the same nominal width as the meter body. The internal
diameter can be derived from the marked flange standard and the type key information
(Appendix, Table 8.2). Any welding beads on the flanges of the inlet pipe shall be
flattened.
• The meter body may be installed in horizontal or vertical position. In case of horizontal
installation, make sure that the meter body is adjusted so that the measuring planes are
in horizontal position. This aims to prevent dirt or moisture in the pipeline from entering the
transducer ports. Vertical installation is only possible if the measuring system is used for dry,
noncondensing gases. The gas flow must be free from any foreign material, dust and liquids.
Otherwise, filters and traps shall be used.
• Avoid installations which may adversely affect the gas flow to be mounted directly
upstream the OPTISONIC 7060.
• Seals at the flange connections between meter body and pipeline must not protrude into
the pipeline. Otherwise, the flow profile and thus the measuring accuracy may be
adversely affected.
• Temperature measuring devices shall be fitted in the outlet pipe no closer than 1.5x DN,
or – in case of nominal widths of ≥  DN 400 – no closer than 300 mm.
