Mechanical installation
WARNING
Leakage or rupture due to connections being made using force.
Risk of severe injury!
Risk of substantial property damage!
Never attempt to overcome misalignments (lateral, angular, longitudinal, torsional)
using force.
Make sure the pipings are flexible enough, if not: use compensators.
Consider the effects of thermal contraction and expansion.
WARNING
Leakage or rupture due to misuse of the mounting material.
Risk of severe injury!
Risk of substantial property damage!
Regarding mechanical strength, with bolts, screws and nuts, use the prescribed
dimensions.
Use the full number of bolts, screws and nuts.
Observe the prescribed thread lubrication (grease or dry!).
Tighten the bolts and nuts in the proper sequence to the specified torque.
If using flanged connections, the correct number of connector elements must be fitted and they
must be tightened with the correct torque in accordance with the screw manufacturer’s
instructions. Comply with the permissible operating data as defined on the type plate. Make sure
that no hazardous fumes can build up in the piping and in the flow meter during commissioning,
decommissioning and dismantling. The flow meter must at all times be completely filled with
liquid during operation. Check the flow meter periodically for tightness of the connections and for
proper functioning. If work is to be done on the installation, before each intervention: release the
pressure in the installation if hazardous liquids are used, wear protective clothing and safety
goggles, place a collecting tray underneath the installation.
Preparing for installation
Check flow meters and installation material.
Compare the data of the flow meter name plate with the expected maximum conditions of the
installation. They may not exceed the flow meter specifications:
Continuous flow rate (Qcont l/h)
Maximum operating pressure (PN bar)
Maximum temperature (°C)
Appropriate connections( threaded, or flanged) and seals (gaskets)
Fasteners for the flow meter
Resistance to liquid to be metered and temperature
