All values are theoretical and are calculated making the following assumptions:
1. All bolts are new and material selection is according to EN 1515-1 table 2.
2. The standard flange gasket material to be used between the flowmeter and mating flanges
should not exceed 75 shore A durometer.
3. All bolts are galvanized and adequately lubricated.
4. The values are calculated for use with carbon steel flanges.
5. Flowmeter and mating flanges are correctly aligned.
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
appropriate. 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)
