1. Safety Instructions

1.1 Correct Usage

•The EF200 measuring system is used to measure the flow of saturated steam,

superheated steam, air and water. Do not use to measure the flow of toxic,

flammable or otherwise hazardous fluids. Use this system only as intended.

•The primarily measured variables are volume flow and temperature. From

these values, the device can use stored data on density and enthalpy to

calculate and output information such as mass flow and heat flow.

•The manufacturer assumes no liability for damage or other accidents caused

by incorrect use of the instrument.

1.2 Dangers and Notes

All instruments are designed to meet state-of-the-art safety requirements,

have been tested, and have left the factory in a condition in which they are

safe to operate. They can, however, be a source of danger if used incorrectly

or for anything other than the designated use. Consequently, always pay

particular attention to the safety instructions indicated in these Operating

Instructions by the following symbols:

1.4 Installation, Commissioning and Operation

•Mounting, electrical installation, commissioning and maintenance of the

device must be carried out by trained, qualified specialists authorized to

perform such work by the operator of the facility. The specialist must have

read and understand this manual before carrying out its instructions.

•The device may only be operated by personnel who are authorized and

trained by the operator of the facility. Strict compliance with the instructions

in these Operating Instructions is mandatory.

•In the case of corrosive fluids (incl. fluids for cleaning), the user is

responsible for verifying the suitability of the material resistance properties of

wetted parts, as regards their in-process resistance to corrosion; the

manufacturer refuses to accept liability.

•The installer must ensure that the measuring system is correctly wired in

accordance with the wiring diagrams.

Note!

There is no longer any contact protection once the housing cover is removed.

•Observe all local regulations governing the opening and repair of electrical

devices.

1.5 Repairs, Dangerous Chemicals

Warning!

The following procedures must be carried out before an EF200 is sent to TLV

for repair:

NOTE: References to use with hazardous fluids are for customers having

special permission and a signed contract with TLV for hazardous use.

•A note must be enclosed with the instrument, containing a description of the

fault, the application and the chemical and physical properties of the fluid

being measured.

•Remove all fluid residues that may be present. Pay special attention to the

gasket grooves and crevices where fluid may be present. This is especially

important if the fluid is dangerous to health, e.g. flammable, toxic, caustic,

carcinogenic, etc.

•No instrument should be returned to TLV without all dangerous material

being removed first.

Incomplete cleaning of the device may result in waste disposal requirements

or cause harm to personnel (burns, etc.). Any costs arising from this will be

charged to the operator of the device.

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.
