Electrical & mechanical installation manual 730962.31.00 page 22 of 52
Warning
• Always observe the general safety regulations and safety instructions given in Section 1
when carrying out any assembly work.
• The OPTISONIC 7060 must only be mounted to pressure-free and vented pipelines.
• Take appropriate measures to avoid potential local or plant-specific dangers.
3.3.1 Choosing flanges, seals and other parts
Use pipeline flanges, bolts, nuts, and seals that withstand the maximum operational
pressure and temperature, as well as ambient and operational conditions (external and
internal corrosion) for the flange connections. For installation lengths and flange dimensions,
see Section 8.1 .
Important
• Always strictly observe the safety instructions for the installation of pressure equipment
including the connection of several pressure components set forth in the Pressure
Equipment Directive 97/23/EC.
• Installation staff must be familiar with the directives and standards applicable for pipeline
construction.
3.3.2 Mounting the OPTISONIC 7060 to the pipeline
An arrow on the meter body indicates the main direction of flow. It is recommended to install
the OPTISONIC 7060 as indicated by this arrow id the device is to be used for unidirectional
flow applications. If the device is to be used in the bidirectional mode, the arrow indicates
the positive direction of flow.
Installation work to be carried out
¾ Take the OPTISONIC 7060 in the right position of the pipeline using the hoisting gear. Only
use the hoisting eyes provided to lift and transport the device. If you use lifting straps,
wrap them around the meter body.
Important
– The hoisting eyes are designed for transporting the measuring device only. Do not lift
the OPTISONIC 7060 using these eyes when additional loads (such as blind covers, filling
for pressure tests) are attached.
– Never attach hoisting gear to the signal processing unit or its mounting bracket and
avoid contact between these parts and the hoisting gear.
– The OPTISONIC 7060 must not turn over or swing while being transported. Flange sealing
surfaces, CONVERTER housing and transducer cover caps may be damaged when the device
is hoisting gear is not attached properly.
– Do not remove the caps protecting the sealing surfaces of the meter body flanges before
necessary.
– Take suitable measures to prevent damage to the measuring device when carrying out
any work (welding, painting) in the vicinity of the OPTISONIC 7060.
¾ Check the correct seat of the flange seals after inserting the first fixing bolts on both sides.
¾ Align the OPTISONIC 7060 so that the mismatch between inlet pipe, meter body and outlet
pipe becomes as small as possible.
¾ Insert the remaining fixing bolts and tighten the nuts cross-wise. Make sure to apply the
tightening torque specified in the project planning.
¾ Mount the pressure line between pressure tap and pressure transmitter.
¾ Fill the pipeline and check the OPTISONIC 7060 installed for leaks.
Note It is recommended to perform a leak test in accordance with the relevant regulations and
standards after completion of the mechanical installation.
