2.1 EF200 Measuring System
The measuring system consists of:
•EF200 remote or compact versions
•EF200 flangeless or flanged connection body
In the compact version, the transmitter and sensor form a single mechanical
unit; in the remote version, they are mounted separate from each other. When
the sensor body must be installed in a high or otherwise difficult to reach
location, the remote version allows more accessible transmitter installation.

2.2 Steam Dryness Fraction Calculator
EF200F ordered with the “Steam Dryness Fraction
Calculator” option is not only capable of flow rate
measurement but can also calculate the dryness
fraction of steam.
Measurable range: 80 to 100% (See the figure on
the right for measurement accuracy)
NOTE: Steam dryness fraction is an indication of steam quality. It shows the
ratio of steam by mass in wet saturated steam.
Steam Dryness Fraction (%)=Steam mass flow rate
󰇡Steam mass flow rate
+ Water mass flow rate󰇢
×100
Caution!
This option cannot be used with EF200W or EF200R.
There are a number of points to consider for the Steam Dryness Fraction
Calculator. Ensure these are met when installing.
Applicable Models
•EF200F (Flanged) DN 25 – 100
Applicable Operating Conditions
•Pressure: 0.1 to 1.0 MPaG (1.0 to 10 barg)
•Temperature: 120 to 185 °C (Saturation temperature for the pressures above)
•Use at a stable pressure and flow rate.
Steam pressure is input in fixed values, therefore correct measurement is
not possible with large pressure fluctuations.
•Make sure the flow rate falls within the measurable range of flow rates at
pressures between 0.1 and 1.0 MPaG (1.0 to 10 barg)
The measurable ranges for flow rate and for steam dryness fraction are
different. Refer to the table below to identify if the Steam Dryness Fraction
Calculator option is applicable.
Caution regarding installation of devices equipped with the Steam
Dryness Fraction Calculator (see 3.3)
•Ensure the required length of straight piping, without using a flow conditioner
•Install on horizontal piping with the display facing downward
Caution!
•When equipped with the Steam Dryness Fraction Calculator function, the
EF200F can be used with steam and water, but cannot be used with air.
•When using the Steam Dryness Fraction Calculator function, the measurement
accuracy for steam mass flow rate will decrease from ±2 °C to ±4 °C.

3. Mounting and Installation
3.1 Transport
•The devices must be transported in the container supplied.
•Devices with nominal diameter 40 to 300 mm (DN 40 to 300) must not be
lifted at the transmitter housing (compact version) or at the connection
housing (remote version) when transporting (see Fig. 2). Use carrier slings
when transporting and put the slings around both process connections.
Avoid chains as these could damage the housing.
Warning!
The center of gravity of the entire measuring device might be higher than the
suspension points of the slings. Therefore, when hoisting, make sure that the
device does not unintentionally turn or slip, as there is the risk of injury if the
device falls.
3.2 Degree of Protection
IP66/67 (EN60529)
Caution!
The devices fulfill all the requirements for IP66/67, Type 4X enclosure.
Compliance with the following points is mandatory following installation in the
field or servicing in order to ensure that IP66/67, Type 4X enclosure protection
is maintained:
•Housing gaskets must be clean and undamaged when inserted in the
gasket groove. The gaskets may need to be dried, cleaned or replaced.
•All housing screws and screw caps must be firmly tightened.
•The cables used for connection must be of the specified outside diameters.
•Firmly tighten the cable entry (see Fig. 3).
•The cables must loop down before they
enter the cable entries (“water trap”, Fig.
3). This arrangement prevents moisture
penetrating the entry. Always install the
measuring device in such a way that the
cable entries do not point up.
•Replace all unused cable entries with
dummy plugs.
•Do not remove the grommet from the
cable entry.
Temperature Ranges
•The maximum allowable ambient and
process temperatures must be
observed (see 6.1.6).
•Ensure both pipeline heat insulation and
mounting position conditions are met
(see 3.3).

3.3 Installation Conditions
A vortex flowmeter requires a fully developed flow profile as a prerequisite for
measuring volume accurately. The following points must therefore be noted
when mounting the EF200 in the pipeline.
Pipe Inner Diameter
When ordering, ensure that the nominal diameter and pipe schedule
(DIN/ANSI/JIS) are correct, since calibration of the flowmeter and therefore the
achievable accuracy of the measuring point are dependent on these
specifications.
3.3.1 Upstream and Downstream Sections
To ensure an undisturbed flow profile,
the vortex flowmeter should be
mounted up- and downstream of any
flow disturbances such as pipe
elbows, reducers or valves, otherwise
the longest possible straight section
of piping should be between the
disturbance and the flowmeter. The
figures on the right show the
minimum section of straight piping up-
and downstream of the disturbance
as multiples of the nominal diameter
of the pipe (D, see Fig. 4-1). If two or
more flow disturbances are located
upstream, the minimum section of
straight piping upstream is equal to
the sum of each individual
disturbance’s requirements up to a
maximum of 50D.
Example:
For 25 mm diameter piping with one
90° elbow:
20D = 20 ×25 mm = 500 mm,
therefore straight piping length must
be at least 500 mm.

With limited space and large pipes,
it is not always possible to use the
upstream sections shown in Fig. 4-
1. In such cases the specially
developed perforated plate flow
conditioner (see 6.6) can be fitted
as shown on the right (see Fig. 4-
2). The flow conditioner is held
between two piping flanges and
centered with the flange bolts. It
reduces the length of the upstream
section downstream from flow
disturbances to 8D while
maintaining full measurement
accuracy. The total length of
straight piping downstream
becomes 10D to 13D. Note that a
flow conditioner cannot be used in
conjunction with the Steam
Dryness Fraction Calculator option.

3.3.3 Installation Orientation
The EF200 can be mounted in any direction in
the piping. An arrow on the meter body shows
the direction of flow.
For measuring liquids in vertical pipes, the
meter should be installed with an upwards flow
direction, position A, to make sure pipes are
com
pletely flooded, avoiding partial filling (see
Fig.
5).
For horizontal pipelines, positions B, C and D
are possible (see Fig.
5). With hot piping (e.g.
steam), position C or D must be selected in
order to respect the maximum permissible
ambient temperatur
e at the electronics.
Do not mount the flangeless model
EF200W at
sizes of 100 mm or larger
in position B for use
with fluids
at temperatures equal to or greater
than
200 °C.
Refer to the Technical Data section for
ambient temperatures (see 6.1.6).
Caut
ion!
For use with the Steam Dryness Fraction
Calculator option, ensure the flowmeter is
mounted in position C.

3.3.4 Pressure Measurement Points
If a pressure measuring point is installed
after the device, ensure that there is a
large enough distance between the
device and the measuring point so that
there are no negative effects on vortex
formation in the sensor.

3.3.5 Pipeline Heat Insulation
Caution!
When insulating, please ensure that a sufficiently large area of the housing
support is exposed. The uncovered part serves as a radiator and protects the
electronics from overheating (or undercooling).
The maximum insulation height permitted is illustrated in Figure 7 (marked
“max.” with a limiting line). These apply to both the compact version and the
sensor in the remote version, as well as all installation orientations.
3.3.6 Minimum Maintenance Space
When servicing, it is necessary to
remove the transmitter housing from the
housing support.
When installing in the piping, be sure to
secure the following cable lengths and
minimum maintenance space:
•Minimum maintenance space in all
directions: A = 100 mm
•Cable length required: L + 150 mm
Caution!
Removing the transmitter from the housing support is to be carried out by
qualified TLV appointed service personnel only!
3.3.7 Ensuring accurate measurements
In some cases where steam is mixed with condensate, it may not be possible
to obtain accurate flow rate measurements.
To remove these causes for concern about flow rate measurements, it is
recommended to install a separator upstream of the flowmeter.

3.3.8 Other Considerations
Vibrations
The correct operation of the measuring system is not influenced by plant
vibrations up to 1 g, 10 to 500 Hz. Consequently, the sensors require no
special measures for attachment. If higher levels of vibration are expected, be
sure to secure piping before and after the flow meter.
Preventing Excessive Flow
Caution!
To ensure long service life for the flowmeter, excessive instantaneous/
periodical flow rates should be held below the flow meter’s maximum flow rate.
Failing to do so might result in damage to the sensor. Special care is
necessary for steam at startup when the pressure is low, or when a valve is
opened rapidly, such as by a solenoid valve, as excessive instantaneous flow
rates often occur.
Pulsating Influences
The ability of the flowmeter to measure correctly may be adversely affected if
there are large variations of pressure or pulsating pressure from compressors
and/or soot blowers. Use the procedures below to minimize pulsating
pressures:
•Move the source of the pulsations to the downstream side of the flowmeter.
Alternatively, put as much distance as possible between the source and the
flowmeter.
•Install a pulsation dampening device, such as a chamber.
•Close the valves before and after the flowmeter when there is no flow.
(This is to prevent false non-zero readings under zero-flow conditions.)
Prevent Mixed Phase Flow
This flowmeter is designed to measure both gases and liquids. However,
accurate measurement cannot be guaranteed when gases and liquids are
mixed together (i.e. gas-liquid mixed phase flow).
Ensure Pipe is Flooded
When measuring liquids ensure that the pipe is flooded, as this will have an
influence on the accuracy of flow rate measurements.
Bypass Lines
The installation of bypass lines can facilitate maintenance and inspections.
When installing a bypass line, use upstream and downstream valves of a type
that does not disturb the flow profile, and secure sufficient length of straight pipe.

3.4 Mounting the Flowmeter
Warning!
Note the following points before installing the flowmeter:
•Remove all packaging used for transport and protective coverings from the
flowmeter before installing the flowmeter in the pipeline.
•Ensure that the inner diameters of the gaskets are identical to or larger than
those of the meter body and process piping. Gaskets that protrude into the
flow affect vortex formation behind the bluff body and lead to inaccurate
measurement. Therefore, the gaskets delivered by TLV come with a slightly
larger inner diameter than the measuring pipe.
•Confirm the gaskets are not dirty or damaged.
•Ensure that the direction of the arrow on the sensor body matches the flow
direction (direction of medium flow in the piping).
•Mount the flowmeter or rotate the transmitter housing so that the cable
entries do not face upward.
Mounting EF200 Flangeless Version
Mounting the flangeless body is carried out using a mounting set (see Fig. 9)
Caution!
By tightening the bolts (tie rods) after fitting the centering rings to the flange
rims on the meter body, it is possible to align the meter body with the piping
and fill the space between the bolts (tie rods) and the meter body. However
the centering rings are not secured to the meter body.

3.5 Mounting the Transmitter (Remote Version)
Where the flowmeter body is installed on piping in a high position or in cases
where there is poor accessibility to the display, the remote transmitter display
may be installed in an easily visible location.
The transmitter can be mounted in the following ways:
•Wall mounting (Fig. 10.A)
•Pipe mounting (with optional pipe mounting kit) (Fig. 10.B)
Caution!
Install the transmitter in a location out of direct sunlight and with an ambient
temperature range of -40 to +80 °C. (See 3.7)
However, the display performance of the LCD may be affected or it may be
difficult to read the display if the ambient temperature is below -10°C or above
+60°C.

B: Pipe Mounting
Unit: mm
Caution!
Take care not to overtighten the nuts when installing the remote transmitter on
piping.
The transmitter housing is constructed from die-cast aluminum, therefore may
be damaged. (Recommended torque: 5 N⋅m)

3.6 Transmitter Housing / Display (Mounting/Rotating)
Rotating the Transmitter Housing
The transmitter housing of EF200 can be rotated on the housing support up
to 350° clockwise or counterclockwise to reposition the optional local display
for easy reading.
This is carried out as follows (see Fig. 11):
1. Loosen the securing screw (minimum one turn).
2. Turn the transmitter housing to the desired position.
3. Fasten the securing screw firmly.
Rotating the Display
The display module can be rotated for easy reading in any position (see Fig. 12).
1. Loosen the securing clamp of the electronics compartment cover using a
hex key.
2. Unscrew cover of the electronics compartment from the transmitter
housing.
3. Optional: pull out the display module with a gentle rotational movement.
4. Rotate the display module into the desired position: Max. 8 × 45° in each
direction.
5. Without display module pulled out:
Allow display module to engage at desired position.
6. With display module pulled out:
Feed the cable into the gap between the housing and main electronics
module and plug the display module into the electronics compartment until
it engages.
7. Reverse the removal procedure to reassemble the transmitter.

3.7 Protect the Transmitter Against Direct Sunlight
Install the transmitter in a location out of direct sunlight if possible. If the
transmitter is subjected to direct sunlight, even when ambient temperature is
within operational range (80 °C or below), the temperature inside the
transmitter may become higher. Additionally, sunlight may promote
deterioration of the finish and appearance of the unit.
If installation outdoors in an uncovered location in unavoidable, installing the
optional sunshade is recommended. (This is not required when installing
compact version with the transmitter oriented downwards.)
