Description
Applications
SITRANS FCS200 is designed for measurement of compressed natural gas (CNG) and is
suitable for filling of gas bottles, furnace control and dispensing.
Figure 3-1 SITRANS FCS200
System components
SITRANS FCS200 makes up the sensor part of a Coriolis flowmeter. The other part is the
transmitter.
SITRANS FCS200 can be remote mounted with the following transmitter types:
● SIFLOW FC070 and SIFLOW FC070 Ex
● SITRANS F C MASS 6000, MASS 6000 Ex and SITRANS F C MASS 6000 Ex d
Further information about the transmitter can be found in the relevant Operating Instructions
available on the SITRANS F literature CD-ROM or on the flow documentation webpage
(http://www.siemens.com/flowdocumentation
).
Design
SITRANS FCS200 is available in DN10, DN15 and DN25.
The sensor consists of 2 parallel measuring pipes, welded directly onto a flow splitter at each
end of the sensor. The flow-splitters are welded directly onto a rigid sensor housing which
acts as a mechanical low pass filter.
The wetted parts of SITRANS FCS200 are available in Hastelloy C-22, while the enclosure is
made of stainless steel W 1.4404 (AISI 304) with a grade of encapsulation of IP66 / IP67
(NEMA 4X).

3.1 Theory of operation
SITRANS FCS200

Table 3- 1 Pressure / Measurement
Pressure Max. massflow
DN10 PN350 42 kg/min
DN15 PN350 200 kg/min
DN25 PN214 500 kg/min
3.1 Theory of operation
The flow measuring principle is based on the Coriolis law of motion.
Particles moving in a rotating / oscillating system will resist the imposed oscillations in a
manner consistent with the mass and velocity (momentum). Oscillations produced by a
Coriolis flowmeter as the process media is accelerated around bends result in phase
distortions of the measuring tubes.
The SITRANS F C sensors are energized by an electromechanical driver circuit which
oscillates the pipe at its resonant frequency. Two pickups, S1 and S2, are placed
symmetrically on either side of the driver.
When the media flows through the sensor, Coriolis force will act on the measuring tube and
cause a tube deflection which can be measured as a phase shift between pickup S1 and
pickup S2.
The phase shift is proportional to the mass flowrate. The frequency and amplitude of the
driver is automatically regulated to ensure a stable output from the 2 pickups in the region of
80 to 110 mV. The temperature of the sensor tubes is measured by a Pt1000, in order to
enable accurate compensation for changes in the material stiffness. As a result the process
media temperature is also accurately measured.
The flow proportional phase signal from the pickups, the temperature measurement and the
driver frequency enable calculation and reporting of mass, density, volume, and temperature.
SENSORPROM
All SITRANS F C Coriolis flow meters feature a SENSORPROM memory unit which stores
sensor-specific calibration data and transmitter settings for the lifetime of the product. The
factory settings matching the sensor are stored in the SENSORPROM. At commissioning the
flow meter commences a typical flow measurement without any initial programming. Also
customer-specified settings are downloaded to the SENSORPROM.

Installing/Mounting
SITRANS F flowmeters with minimum IP67/NEMA 4X enclosure rating are suitable for indoor
and outdoor installations.
● Make sure that pressure and temperature specifications indicated on the device
nameplate / label will not be exceeded.
WARNING
Installation in hazardous location
Special
requirements apply to the location and interconnection of sensor and
transmitter. See "Installation in hazardous area" (Page 10)
4.1 Installation safety precautions
WARNING
In applications with working pressures/media that can be dangerous to people,
surroundings, equipment or others in case of pipe fracture, we recommend that special
precautions such as special placement, shielding or installation of a security guard or a
security valve are taken when the sensor is mounted.
● Ensure that stresses and loading caused by earthquakes, traffic, high winds and fire
damage if appropriate are taken into account during installation.
● 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.
● Provide adequate protection to minimise any risk of contact with hot surfaces.
WARNING
Prevent personal injuries by assurin
g that operation below pressure guards cannot take
place, if working with vacuum or fluids boiling readily.

Rupture disc
The two black rupture discs prevent overpressure in the enclosure. In case of a tube fracture
generating overpressure in the enclosure, the rupture discs will immediately burst and keep
the pressure at a safe level.
Figure 4-1 Rupture safety disc
Note
The enc
losure of the sensor does not fulfil any containment function.
4.2 Orienting 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 (a forward/reverse flow calibration is available as an option).

Orienting the sensor
SITRANS FCS200 operates in any orientation, but Siemens recommends orienting the
sensor in one of the following ways:
1. Vertical orientation with an upwards flow
Figure 4-2 Vertical orientation, upwards flow
2. Horizontal installation, tubes sideways
Figure 4-3 Horizontal mounting, tubes sideways
3. Horizontal installation, tubes up
Figure 4-4 Horizontal orientation; tubes up
4.3 Mounting the sensor
● Install two pipe hangers with rubber inserts symmetrically and stress free on the
enclosure ends as shown below.
Sensor end dimensions are described in the Dimensions chapter (Page 34) of the
Operating Instruction
s.
● Mount the pipe hangers on a solid, vibration free foundation or frame
● Center the connecting pipelines axially in order to assure a stress-free installation.

Avoid vibrations
● Make sure that any valves or pumps upstream of the sensor do not cavitate and do not
send vibration into the sensor.
Figure 4-5 Eliminate vibrations
Avoid cross talk
If operating more than one flowmeter in one or multiple interconnected pipelines there is a
risk of cross talk.
Prevent cross talk as follows:
● Mount sensors on separate steelframes
● Keep sufficient distance between the sensors (distance depends on application)
● Decouple the pipelines.

Troubleshooting/FAQs
8
8.1 General information
Incorrect and unstable measurements, especially at low flows, are typically a result of an
unstable zero point due to:
● Incorrect installation
● Vibrations/Cross talk
In the following a 2 steps guide to troubleshooting is provided:
Step 1 Preliminary application inspection
Step 2 Application improvement
The guide will enable you to trace the reason for incorrect measurements and to improve the
application.
8.2 Step 1: Inspecting the application
The first step in the troubleshooting procedure is to check for some easily resolved
problems.
Check that:
● Sensor and Sensorprom memory unit correspond (serial numbers)
● The sensor is properly installed.
● The sensor is located in a vibration-free position. Vibrations can disturb the sensor and
therefore cause measurement error.
Resolving step 1 problems
1. Make sure that the serial numbers on the sensor and the Sensorprom memory unit are
identical.
2. Make sure that the sensor is installed as described in the installation chapter (Page 15) of
the sen
sor manual.
3. Flush the pipe systems and the sensor for several minutes at maximum flow rate to fill in
the process media.

8.3 Step 2: Improving the application
SITRANS FCS200
28 Operating Instructions, 02/2011, A5E02508199-01
8.3 Step 2: Improving the application
Incorrect installation of the sensor
Especially for low flow rates, i.e. flow rates less than 10% of the maximum capacity of the
flowmeter, it is important that the sensor is correctly and stably installed.
If the sensor is not correctly fixed in place, the zero point of the sensor will move, leading to
measuring errors.
1. Secure that the sensor has been installed and fixed to a solid vibration free foundation or
frame.
2. Tighten the sensor brackets in order to stabilize the flow.
Vibrations and cross talk
Vibrations in the pipe system are normally generated by pumps.
Typically, cross talk is generated by two sensors positioned in close proximity in the same
pipe, or installed on the same rail or frame.
1. Set Low Flow Cut-Off to zero %
2. Turn off any pump to see if the zero point stability improves, i.e. if the flow rate fluctuation
in kg/h is reduced.
If the sensor is disturbed by vibration from a pump, the installation should be improved or
the pump replaced.
3. Check for cross talk.
Turn off the power to the other flowmeter(s) and wait approximately 2 minutes. Then
check if the zero point stability has improved, i.e. that the fluctuation in kg/h has been
reduced. If this is the case, the sensors disturb each another and the installation should
be improved.

Glossary
ASIC
Application-Specific Integrated Circuit is an integrated circuit (IC) customized for a particular
use, rather than intended for general-purpose use.
CNG
Compressed natural gas, or CNG, is natural gas under pressure which remains clear,
odorless, and non-corrosive. Vehicles can use natural gas as either a liquid or a gas.

Coriolis
The Coriolis effect is an apparent deflection of moving objects from a straight path when they
are viewed from a rotating frame of reference. The effect is named after Gaspard-Gustave
Coriolis, a French scientist who described it in 1835. The Coriolis effect is caused by the
Coriolis force, which appears in the equation of motion of an object in a rotating frame of
reference.
DFT
The discrete Fourier transform (DFT) is one of the specific forms of Fourier analysis. As
such, it transforms one function into another, which is called the frequency domain
representation, or simply the DFT, of the original function (which is often a function in the
time domain). The DFT evaluates enough frequency components to reconstruct the finite
segment that was analyzed. The DFT is thus a transform for Fourier analysis of finite-domain
discrete-time functions.
EMC
Electromagnetic compatibility (EMC) is the branch of electrical sciences which studies the
unintentional generation, propagation and reception of electromagnetic energy with
reference to the unwanted effects (Electromagnetic Interference, or EMI) that such energy
may induce. The goal of EMC is the correct operation, in the same electromagnetic
environment, of different equipment which use electromagnetic phenomena, and the
avoidance of any interference effects.

IP
An IP (Ingress Protection) number is used to specify the environmental protection of
enclosures around electronic equipment. These ratings are determined by specific tests. The
IP number is composed of two numbers, the first referring to the protection against solid
objects and the second against liquids. The higher the number, the better the protection. For
example, in IP67 the first Number (6) means that the device is totally protected against dust,
and the second (7) that it is protected against the effect of immersion between 15cm and 1m
NAMUR
Normenarbeitsgemeinschaft für Meß- und Regeltechnik in der Chemischen Industrie
(NAMUR). NAMUR is a group representing the interests of the chemical industry which
create standards for instrumentation and electrical devices used in industrial plants.
PED
The Pressure Equipment Directive (97/23/EC) is the legislative framework on European level
for equipment subject to a pressure hazard. It was adopted by the European Parliament and
the European Council in May 1997 and has been obligatory throughout the European Union
since May 2002.
SENSORPROM
All sensor related settings/data saved on an EPROM. SENSORPROM technology
automatically configures the transmitter at start up providing calibration data, pipe size,
sensor type, and output settings. The SENSORPROM automatically stores values or
settings changed by users, and automatically re-programs any new transmitter without loss
of accuracy.
Turndown ratio
'Turndown ratio' is a flow measurement term indicating the range a specific flow meter, or
meter type, is able to measure with acceptable accuracy. It is also known as rangeability. If a
gas flow to be measured is expected to vary between 100,000 m³ per day and 1,000,000 m³
per day, the specific application has a turndown ratio of at 10:1. Therefore the meter requires
a turndown ratio of at least 10:1.
Zero point adjustment
In order to measure accurately with a measuring instrument it is important that zero and gain
have been calibrated. All Coriolis sensors are calibrated before they are sent out to
customers. However, Coriolis sensors are very sensitive, and several factors might move the
zero point, e.g installation, pressure, temperature and even very small vibrations coming
from the process. All these factors are customer specific and can’t be simulated at the
factory. Therefore Siemens recommends to carry out a zero point adjustment before use.
