Installing/mounting 4.1 Basic safety notes WARNING Exceeded maximum permissible operating pressure Risk of injury or poisoning. The maximum permissible operating pressure depends on the device version, pressure limit and temperature rating. The device can be damaged if the operating pressure is exceeded. Hot, toxic and corrosive process media could be released.
Installing/mounting 4.1 Basic safety notes 4.1.1 Installation location requirements WARNING Insufficient air supply The device may overheat if there is an insufficient supply of air. ● Install the device so that there is sufficient air supply in the room. ● Observe the maximum permissible ambient temperature. Refer to the information in the section Technical data (Page 105).
Installing/mounting 4.2 Installation instructions 4.1.2 Proper mounting WARNING Loss of type of protection Risk of explosion. Damage to device if the enclosure is open or not properly closed. The type of protection specified on the nameplate or in Technical data (Page 105) is no longer guaranteed.
Page 31
Installing/mounting 4.2 Installation instructions CAUTION Electromagnetic fields Do not install the flowmeter in the vicinity of strong electromagnetic fields, for example near motors, variable frequency drives, transformers etc. Upstream / downstream ● No pipe run requirements, that is straight inlet/outlet sections, are necessary. ●...
Installing/mounting 4.2 Installation instructions 4.2.1 Orientation of the sensor Flow direction The calibrated flow direction is indicated by the arrow on the sensor. Flow in this direction will be indicated as positive by default. The sensitivity and the accuracy of the sensor do not change with reverse flow.
Page 33
Orienting the sensor The sensor operates in any orientation. The optimal orientation depends on the process fluid and the process conditions. Siemens recommends orienting the sensor in one of the following ways: 1. Vertical installation with an upwards flow (self-draining)
Installing/mounting 4.2 Installation instructions Installation in a drop line is only recommended if a pipeline reduction or orifice with a smaller cross-section can be installed to create back-pressure and prevent the sensor from being partially drained while measuring. ① Back pressure orifice ②...
Page 35
Installing/mounting 4.2 Installation instructions Avoid vibrations ● Make sure that any valves or pumps upstream of the sensor do not cavitate and do not send vibrations into the sensor. ● Decouple vibrating pipeline from the flow sensor using flexible tube or couplings. Figure 4-7 Non-flexible pipes not recommended in vibrating environment Figure 4-8...
Installing/mounting 4.2 Installation instructions Prevent cross talk in one of the following ways: ● Mount sensors on separate frames ● Decouple the pipeline using flexible tube or couplings Figure 4-9 High risk of cross talk when using non-flexible pipes Figure 4-10 Low risk of cross talk when using flexible pipes and separate frames 4.2.3 Hydrostatic testing...
Installing/mounting 4.3 Disassembly In both cases, insulation can have the unexpected effect of shrouding other attached components not intended or designed for the process temperatures. When installing an FCS300 sensor with insulation, observe the following rules: ● Do not cover any part of the transmitter pedestal. The pedestal is designed to separate the process temperature from the ambient around the DSL or transmitter electronics housing.

Technical data 11.8 PED Division according to the danger potential Flowmeters which are categorized as piping are divided into categories according to danger potential (medium, pressure, nominal diameter). The flowmeters fall into the categories I to III or they are manufactured according to Paragraph 3 - Sound Engineering Practice (SEP). The following criteria are decisive for assessment of the danger potential and are also shown in Diagrams 1 to 4, see Diagrams (Page 111).

Technical reference Theory of operation The Coriolis principle of measurement The flow measurement is based on the Coriolis law of motion. Particles moving in a rotating / oscillating system will resist imposed oscillations in a manner consistent with their mass and velocity (momentum).
Technical reference A.2 Sensor dimension dependent default settings Digital signal processing (DSP) The analog to digital conversion takes place in an ultra low noise sigma delta converter with high signal resolution. With fast digital signal processing mass flow and density values are calculated using a patented DFT technology (Discrete Fourier Transformation).
