• The FMT200-D measuring systems are intended exclusively for measuring the flow of
gaseous media.
• The device may only be used in accordance with the application specified on the order
confirmation; other operating conditions may prevent the device from functioning correctly,
cause damage to it or even damage it beyond repair.
• Care must be taken to ensure that the measuring media used do not impair the chemical and
physical properties of the components that come into contact with the fluids concerned.
• The threshold value for alternating load cycles corresponds to AD-2000 instruction sheet S1,
Section 1.4 and is not calculated or checked by the manufacturer.
• The device should be included in any regular maintenance activities that are carried out on
the entire system.
• The materials used must be checked by the user to ensure their suitability for the application
concerned.
• The maximum operating conditions relating to pressure and temperature, as stated on the
name plate / in the operating instructions, must not be exceeded.
• When installing and disassembling pipe components or flowmeter sensors, ensure that the
pipeline has been depressurized.
• Before carrying out installation work on pipelines used to carry aggressive or toxic measuring
media, media that may be classed as irritant, or other kinds of hazardous media, the fluids
concerned must be adequately flushed out. Compliance with the relevant accident
prevention regulations must also be ensured.
• If damaged, components must no longer be used. They must be taken out of circulation and

1.2.2 Installing / Disassembling pipe components
• During installation, it is important to ensure that the flow direction corresponds to the
attached label.
• When welding the weld-on adapter, remember to observe the relevant welding instructions.
The amount of heat introduced must be kept to an absolute minimum to prevent warping of
the mounting flange's sealing surface.
• In the case of flanged connections, flat gaskets must be installed. These must be in perfect
condition and resistant to the measuring media.
• Before installing pipe components or flowmeter sensors, check all components and gaskets
for damage.
• Pipe components must not be installed under tension, otherwise the pipeline may be
subjected to impermissible forces.
• When assembling the flanged connections, use screws that offer the required strength and
dimensions.
• The screws must be tightened evenly and to the required torque.
• Once the pipe components have been installed, the insertion connection must be sealed by
means of a blind flange plus gasket or by closing a shut-off device (if present).
1.2.3 Installing / Disassembling the flowmeter sensor
• Installation in the pipe component or weld-on adapter is only possible if the flowmeter sensor
data matches the measuring point specifications.
• It is very important to use the O-ring supplied (not a flat gasket). This is resistant to
measuring media and should be inserted in the groove provided in the pipe component
flange.
• Take care not to damage the measuring elements when inserting the flowmeter sensor into
the pipe component, as this is not permitted.
• The flowmeter sensor should be firmly bolted together with the flange of the insertion
connection. The screws must be tightened evenly to the required torque.

The mass flowmeter works according to the thermal measuring principle of a hot-film
anemometer. Heat is drawn out of a heated body by a gas circulating around it. This flow-
dependent cooling is utilized as a measuring effect. Since the heat loss depends on the number
of particles that hit the surface of the heated body, it is possible to directly determine the mass
flow rate. This means there is no need for pressure and temperature influences to be
compensated.
The calibration of the devices is done on a highly precise flow test machine with air as
calibration medium. For standard biogas applications, the calibration data are subsequently
converted, whereby a medium gas composition is based on 53 Vol% methane, 45 Vol% carbon
dioxide and 2 Vol% air. Devices for applications that clearly deviate from this gas composition
must be ordered with a special calibration for biogas. In this case, the exact gas composition is
to be specified with the order.
The measuring systems of the FMT200-D series consist of the following components:
• Flowmeter sensor and
• Pipe component of various types.

Design and function
12 Sensyflow FMT200-D 42/14-37-EN
2.1 Pipe components
Pipe components for nominal diameters 1 ... 3“ are available in various designs. In addition it is
possible to integrate the flowmeter sensor directly into pipes of DN 100 ... DN 250 (4 ... 6“) or
into pipes with non-circular cross-sections using a weld-on adapter.
The pipe components and weld-on adapters guarantee the defined installation of the transducer
in the pipeline. Moreover, they allow simple removal and installation of the transducer for
inspection and/or cleaning. By closing the pipe component with a blind flange, it is possible to
use the measuring section even without installed transducer.
The versions available as standard - depending on the respective nominal diameter and the
desired adaptation - are shown in chapter 8 Specifications.
2.2 Flowmeter sensor
The flowmeter sensor designed as a plug-in unit contains, besides the sensor unit, the sealed-in
transmitter circuitry accommodated in the sensor head. The circuitry mainly consists of the
differential temperature control unit for the sensor elements, a memory for all parameters that
are specific to the measuring point, a connector for the LCI adapter, and the computing power
for creating flow-dependent data records.
In addition, a flow-linearized analog signal of 0/4…20 mA (electrically isolated) is directly
provided. No special supply/evaluation device is required. The flowmeter sensor is installed in
the pipe component as a plug-in unit with a centering pin in a defined manner. See chapter 8
Specifications.

To achieve the stated measuring accuracy, the steadying lengths
seen above must be provided. For combinations of inlet run dist-
urbances, e. g. valve and reducer, you must always consider the
longer inlet run length. In confined spaces at the mounting location
the outlet run length can be shortened to 3 x D. The reduction of the
minimum inlet run length, however, will impact on the achievable
accuracy.
High repeatability of the measuring value is still provided. Under
certain circumstances, special calibration can be performed for insuf-
ficient steadying lengths. For this purpose and in individual cases
consulting is necessary.
For gases with extremely low density (hydrogen, helium) the stead-
ying lengths must be doubled.

3.2 Verifying the conditions
Important
Before installing and commissioning the device, thoroughly read the operating instructions and
observe the following instructions.
For each measuring system a calibration certificate is delivered which contains all the key
information such as the measuring medium, measuring range, nominal diameter, serial number
and order number.
Especially observe the following:
• The operating conditions of the measuring point must fully comply with the specification in
the calibration certificate, such as the permissible measuring medium, operating
temperature, operating pressure, measuring range, etc.
• Observe the permissible ambient temperatures.
• Correctly install the pipe component or weld-on adapter. Observe the flow direction!
• Ensure compliance with the recommended inflow/outflow sections
• Correctly mount the flowmeter sensor to the pipe component.
• Correctly install all gaskets and check them for perfect condition.
• Correctly install all electrical connections.
3.3 Selecting the installation site
• The installation site must fulfill the requirements stated in the chapter “Technical Data:
Environmental Conditions”.
• In order to prevent the measuring accuracy from being affected, the appropriate inlet and
outlet sections must be provided. These steadying lengths ensure that any disturbances of
the flow profile are eliminated before reaching the actual measuring point at the flowmeter
sensor.
• Provide straight, undisturbed pipes for steadying. The lengths of these pipes depends on the
type of disturbance on the inlet side (see chapter 3.1).
• Components affecting the flow like valves or shut-off devices should be installed on the
outlet side, i. e. downstream of the measuring point.
• When using a weld-on adapter to install the flowmeter sensor, observe chapter 9.2.
Make sure that all installed devices can be accessed easily.

3Pipe component
• The flow direction must correspond to the arrow indicated on the pipe component.
• The gaskets used must not alter the cross- section of the opening in the pipeline and must
ensure complete tightness once the flowmeter sensor and pipe component have been
installed.
• The centering pin on the pipe component or weld-on adapter must be located on the outlet
side downstream of the measuring point.
• Check the supplied gasket G according to DIN 11851 between the transducer and the pipe
component / weld-on adapter for signs of damage prior to installation.
• When using flange-type pipe components all flange screws must be installed properly.
• Connecting threads are to be connected with the pipelines of the system using suitable
sealant. All screw connections are to be checked for tightness.

3.5 Weld-on adapter for Sensyflow FMT200-D
Length of weld-on adapter at delivery: L = 117 mm (4.6").
For outer pipe diameter 100 ... 150 mm (4 ... 6“)
Prior to welding the weld-on adapter must be shortened to the appropriate length so that it has the length L after welding. This results in a
measuring position in the middle of the pipeline.
L = H1 - 1/2 x Ø Douter with H1 = 120 mm (4.72“)
For outer pipe diameter 150 ... 250 mm (6 ... 10“)
Shorten the weld-on adapter in such a way that the fixed length L = 45 mm (1.77“) is achieved after welding. As a result, the measuring position
is not in the middle of the pipeline. For a correct calibration it is therefore mandatory to specify the exact inside diameter and wall thickness of
the pipe in mm when ordering.

Important
Always mount the weld-on adapter together with the lock nut to the pipeline. Mounting it at a later time is not possible.
Observe thickness of pipeline wall and degree of shrinkage when welding on.
It is essential to maintain a right angle to the pipe axis (max. tolerance: 2°).
The adapter centering pin must be exactly aligned with the pipe axis in the flow direction (outflow side, behind the
measuring point).
Once welding is complete, there must be a passage of at least 28 mm (1.10 inches) free for the purpose of mounting
the flowmeter sensor; drill to create if necessary.
For outer pipe diameter 100 ... 150 mm (4 ... 6“) The distance H1 from the upper edge of the adapter to the the pipe
central axis must be within a tolerance of ± 2 mm (0.08“).

6).
This adapter is available as a separate accessory and comes supplied together with the
relevant software.
The following parameters can be modified or read in:
Read device data Show current settings
Measurement range Selection within the calibrated measurement range
Low flow Low flow suppression 0...20 % of the upper range limit
Filter factor Attenuation, 1 ... 500 can be selected (default: 50)
Output in the event of an error Minimum (lower than 3.5 mA) or maximum (greater than 22.5 mA)
Analog output 0 / 4 ... 20 mA
Save modified data Save settings
Factory setting Select default setting
Status Check function
Reset Restart
Print out Print out current settings
Password For service technicians only
To activate the configuration changes, the device must be restarted. To do so, use the
command "restart reset" or briefly interrupt the power supply for approximately 10 seconds.

If failures occur (e.g., sensor wire break), the 0/40 ... 20 mA output will adopt the configured
control value.
In the event of an error, the following settings can be made:
- Minimum < 3.5 mA
- Maximum > 22.5 mA
Important
Default preset in case of a fault
Maximum 0 ... 20 mA
Minimum 4 ... 20 mA
These settings can be modified using the LC interface and the corresponding configuration
software.
