Manufacturer's design
and safety statement
1. Responsibility for the choice of lining and electrode materials with regard to their abrasion
and corrosion resistance lies with the purchaser; the effect of any change in process medium
during the operating life of the flowmeter should be taken into account. Incorrect selection
of lining and/or electrode materials could lead to a failure of the flowmeter.
2. It is the responsibility of the user to ensure that stresses and loading caused by earthquakes,
traffic, high winds and fire damage are taken into account during installation, when appropri-
ate. These forces are not taken into account during flowmeter design.
3. It is the responsibility of the user to ensure that the flowmeter is installed such that it does not
act as a focus for pipeline stresses. External loadings are not taken into account during
flowmeter design.
4. During operation do not exceed the pressure and/or temperature ratings indicated on the data
label or in the installation instructions.
5. It is the responsibility of the user to ensure that all installations include over pressure protection,
means for draining/venting, and that adequate protection is provided to minimise
any risk of contact with hot surfaces.
6. Under the Pressure Equipment Directive this product is a pressure accessory, and not
approved for use as a safety accessory, as defined by the Pressure Equipment Directive.
7. Removal of the terminal box except by Siemens Flow Instruments or their approved agents
will invalidate the PED conformity of the product.
In accordance with the Pressure Equipment Directive (97/23/EC)
Tighten the cable glands and the cable entries
to obtain optimum sealing. The cable entry
gasket must obtain firm contact with the cable.
For sensors DN 2+3 in applications with low
conductivity and high vibration level of cables
use low noise coax electrode cable.
