SAFETY INSTRUCTIONS

1.1 Intended use
-
-
Warning!
The operator of these measuring devices is solely responsible for the suit-
ability, intended use and corrosion resistance of the selected materials. In
particular. it must be ensured that the materials selected for the wetted
parts of the ow meter are suitable for the process media to be measured.
The meter must not be exposed to external loads. These ow meters are
primarily designed for static applications.
Hot process media can lead to hot surfaces! There is a risk of burns where
the surface temperatures are above +70 °C.
Suitable protective measures should be taken, e.g. protection to prevent
contact.
The contact protection must be designed such that the maximum ambient
temperature around the equipment is not exceeded.
The equipment may only be operated within the pressure and voltage limits stated on the
free of hazardous media and pressure.

Information!
All instruments are carefully checked for proper function before shipment.
On receipt, immediately check the outer packing carefully for damage or
signs of improper handling.
Report damage to the carrier and your local sales sta. In such cases, a
description of the defect, the type and the serial number of the device is
indicated.
Unpack the unit carefully to avoid damage.
Check the delivery against the packing list for completeness. Check the
name plate, if the delivered ow meter according to your order. Check that
the correct voltage supply is specied.
Special requirements VdS: The version with rolled grooved ends may only
be used in combination with VdS-approved pipe couplings manufactured
by Anvil (all Gruvlok mechanical grooved couplings), Jinan Meide (cast-
ing couplings type 1G), Minimax, Modgal, Tyco (Grinnell Mechanical and
G-Fire steel IPS couplings) and Victaulic (except pipe couplings of the type
"Style77").
