3 Operational mode and system design

3.1 Measuring principle

If a medium flows with sufficient velocity through the
horizontally or vertically arranged measuring chamber (1) if
the TSK fitting, the paddle (2) will swivel around the axle until
the force of the medium and the opposing force of the
paddle surface plus the spring tension establish equilibrium.
The angular position or the position of equilibrium ( ) of the
paddle (2) in the measuring chamber (1) is the measure for
the flow. The encapsulated ring-type permanent magnet (4)
at the end of the paddle axis (3) then transmits this position
to the scale (6) and the optional electronic evaluators
through the magnet tracking indicator (5) system. This
happens safely and without packing glands.
The flow rates shown on the scale only apply to the
calibrated medium or to a medium with the same physical
characteristics.

3.2 System design

The TSK flowmeter mainly consists of the fitting with the
measuring chamber, the measuring elements “torsion spring”

and “paddle,” the magnet tracking indicator system and the

indicator unit.
The flowmeter is manufactured as a sandwich-type
construction and available for the nominal sizes from DN 50
to DN 400.

2 Applications

The TSK meter is suitable for flow measurement of liquid
products in pipes. The special advantage is that it can be
used for all directions of flow. It shows the current flow
rate in volume or mass per unit in time.

Applications: flow measurement, dosing, monitoring,
adjusting and control of liquid and gaseous products.

The meter’s design makes it ideal for processes under

difficult and adverse operating conditions.
The devices are available with additional electrical

equipment for process monitoring and control.

TSK1 Installation and Operating Instructions

5.4 Analog output with the KINAX 3W2 angle-

of-rotation transmitter

The signal output of the angle-of-rotation transmitter is
factory-calibrated to the scale values. The signal output is 4­20 mA in 2-wire connection; or alternatively 0-20 mA in 4- or
3-wire connection. The signal output of 4 mA corresponds to
the flow rate scale value of 0 (0 mA for the 0-20 mA version).

5.6 mA corresponds to 10% of the flow rate scale value

(2 mA). 20 mA corresponds to 100% of the flow rate scale
value.

Use in hazardous areas:

The angle-of-rotation transmitter is a component approved
for hazardous areas. When used in hazardous areas, all the
values and instructions indicated in the certificate of approval
must be observed. Auxiliary power is fed through an
approved intrinsically safe circuit of 12-30 V. To prove
intrinsic safety, only authorized electrical equipment may be
interconnected. Please take note of the maximum
permissible ambient temperature of 60°C/75°C for the
transmitter and the process temperature.

7.1 Installation conditions

The measuring device can be installed vertically or
horizontally (according to the direction of flow indicated in
the order). The nominal size of the product line to be
connected must correspond to the nominal size of the
measuring device. The best installation position is between
loose flanges. When installing the device between weld-on
flanges, the flange hole pattern has to be turned so that the
indicator unit is in a horizontal position if the pipe
arrangement is horizontal. The nominal size of the product
line to be connected must correspond to the nominal size of
the device. Avoid fittings converging on one side directly in
front of the device.
The adequate distance to ferromagnetic parts must be
observed. During installation, the standard inlet section
must be 5 x D and the standard outlet section 3 x D.

We recommend that the lateral distance between two
adjacently mounted devices be 300 mm. The devices can
be mounted close together if vertically offset by one device
length. The minimum lateral distance for interfering steel
parts should be 200 mm. In case of doubt, check the
interference by moving the device back and forth in the
selected distance by about 200 mm and testing whether the
pointer position changes.

Select the mounting location so as to enable a reliable
reading of the scale values. Please take note as well of the
space requirement for a possible disassembly of the device.

6.2 Influence of ambient temperature

1. Without electrical equipment and with limit transducer

without influence

2. With ES transmitter:

0.5% / 10 K reference temperature 20°C

3. With KINAX 3W2 transmitter:

0.2% / 10 K reference temperature 20°C

6.3 Influence of fluid temperature

Deviations in fluid temperature from the temperature
observed during calibration can result in a proportional
display fault because of the corresponding change in
density. Changes in viscosity cause a non-linear display
fault.

7 Conditions of use

The VDI/VDE guidelines 3513, Sheet 3, must be observed.
The meter is suitable for Liquids with sufficient flowability that
are free of solids, do not bond and do not tend to settle.

For paddle-type devices, viscosity factors must not be
considered physically. They do not play any role or play an
insignificant role when the flow rates are high.

Basically, avoid activation using solenoid valves.
Use connecting bolts and gaskets in the prescribed

dimensions. The gaskets must be suitable for the operating
pressure, the temperature and the measured medium. With
PTFE- and PP coated devices, use gaskets whose interior
and exterior diameter correspond to the sealing strip of the
device.

Tighten the flange bolts crosswise so that the process
connections are tight. Pay particular attention to the
tightening torques of screws, especially with PTFE- and PP­coated devices. The maximum torques are:

vertical: from the bottom to the top

Caution:

When mounting the device in the horizontal position, make
sure the indicator unit is not pointing upwards. This is to
prevent water lodging on the glass window and entering the
device under the protective shroud of the housing.

7.1.1 Mounting/start-up

Before installation, check whether the measuring element is
free from foreign bodies. The instrument must be mounted
perpendicularly or horizontally according the planned and
confirmed direction of flow.

The nominal size of the device and that of the pipes must be
the same. The pressure stages and, hence, the dimensions
of the flanges must coincide. The surface roughness of the
flange sealing surface must be suitable for the prescribed
gaskets.

Check whether the mounting clearance between the flanges
of the pipes corresponds to the assembly dimension of the
device plus two gaskets. To achieve stress-free mounting,
the flanges of the pipes must be aligned parallel to each
other.

If the device is calibrated to more than 1.013 bars absolute
pressure, the valve is usually installed behind the flowmeter.
At 1.013 bars absolute pressure (free exhaust) install it in
front of the device.

Device slowly flush to avoid a surge of gas bubbles.

(following VDI/VDE Guideline 3513)
Please check whether the pipe is adequately stable so that

vibration or swinging of the device is out of the question.
(Do not use steel mounting parts directly on the device.)

7.1.2 Device settings

The measuring equipment is delivered ready for operation
according to your order specifications. The limit
transducers are set to the desired values. If you have
submitted no requirements, the basic setting for

1 contact device: - Minimum contact switching point at 20%
of descending flow (damped/closed-circuit principle).

2 contact devices: Minimum contact switching point at 20%
of descending flow and maximum contact switching point at
90% of ascending flow

7.1.3 Adjusting the limit transducer

The contacts are adjustable through the contact position
indicators located on the scale. Dismantle the indicator
cover, unfasten the contact position indicators, set to the
desired value and reattach them.

7.1.4 Operation in hazardous areas

7.1.4.1 Without electrical equipment

The basic version of the flow meter is a non-electrical device
without its own ignition sources and meets DIN EN 13463-1
requirements. It can be used in hazardous areas that
require Category 2 equipment.

7.1.4.2.1 Marking for the device when the
SJ 3,5…N… limit transducer is built in

7.1.4.2.2 Marking for the device when the
ES magneto-electric transmitter is built in

Since the device does not have its own power sources that
would result in a temperature increase, the fluid temperature
is decisive for the maximum surface temperature.

When used in potentially explosive dust atmospheres, the
device must be cleaned regularly in order to avoid deposits
exceeding 5 mm.

7.1.4.2 With built-in electrical limit transducers

When the limit transducers are installed, the device becomes
an electrical assembly and receives a marking in accordance
with DIN EN 50014 from the entire device with the built-in
electrical limit transducers.

The electrical and thermal data and the special conditions of
the EC Type Examination Certificate of the built-in limit
transducers must be observed (see also the diagram in
Section 7.3.1).

The influence of the fluid temperature on the built-in limit
transducers must be observed. The overtemperature of the
maximum fluid temperature based on the maximum ambient
temperature must be considered with a factor of 0.25.

Example for built-in limit transducer:

Max. ambient temperature T
Max. fluid temperature Tm = 120°C
Factor for brought-in heat F = 0.25
Temperature class T4

Tü = Overtemperature
Ta = Ambient temperature of

In accordance with the tables in the
PTB 99 ATEX 2219 X EC Type Examination Certificate, the
SJ 3,5-… N… inductive sensor must be operated in the
T5 temperature class with an intrinsically safe circuit that
does not exceed the maximum values of the Type 3 circuit.

When using the device in hazardous areas, follow the
applicable national installation rules.

7.1.4.2.3 Marking for the device when the
KINAX 3W2 angle-of-rotation transmitter is
built in

7.1.4.3 Atmospheric conditions

In accordance with EN 1127, a “potentially explosive

atmosphere“ is defined as a mixture of air and combustible

gases, vapour, mist or dust under atmospheric conditions.
Such conditions are defined in EN 13463-1, para. 1, with
values Tatm = -20 °C to +60 °C and Patm = 0.8 to 1.1 bar.
Outside this range, safety parameters for most ignition
sources are not available.

Usually, paddle-type flow meters operate under operating

conditions outside the atmospheric conditions of 0.8 to

1.1 bar. Irrespective of the zone classification –safety

parameters of explosion protection – are basically not
applicable to the inside of the measuring tube. Therefore
operation with combustible products is only allowed if a
potentially explosive air mixture is not formed inside the flow
meter. Where this condition is not met, the operator will need
to assess the ignition hazard in each individual case and
give due consideration to existing parameters (e.g. pressure,
temperature, process product, materials of construction for

the measuring tube).

7.1.4.4 Ground connection

In paddle-type flow meters, it is possible under operating

conditions for charge separation to occur in the measuring
tube due to the transport of non-conductive fluids and/or
when the flow comes into contact with non-conductive
internals (e.g. liners, floats).

For that reason, variable-area flow meters must be
permanently grounded by the operator by way of the process
connections (flanges) in order to discharge electrostatic
build-up. The operator is also responsible for extending the
ground continuity of the process pipeline.

If grounding cannot be made via the process connections
(plastic process connections or undefined connections), the
flow meter must be connected to the local ground potential
via the flanges. This connection only ensures electrostatic
grounding of the device and does not meet the requirements
for equipotential bonding.

7.2 Ambient conditions

7.2.1 Ambient temperature ranges

Without electrical accessories: -40°C to +80°C
With limit transducer: -40 °C to +65°C
With KINAX signal output: -40°C to +60°C
With ES signal output: -40°C to +70°C

For the hazardous area version, take note of the maximum
ambient temperatures depending on the temperature class
as specified in the Type Examination Certificate.

7.3.2 Diagram: Max. ambient temperature based on the fluid temperature for the built-in sensor Type ES

7.3.1 Fluid temperature ranges

Type Fluid temperature
TSK1-C/S -40°C to 200°C

TSK1-K 0°C to 80°C
TSK1-P -20°C to 125°C

A pulled-forward indicator unit is necessary if the fluid
temperature falls below –40°C or rises above 200°C.

The effect of the fluid temperature on the indicator unit and
its built-in components must be considered

7.3.3 Fluid pressure limit

TSK1-C
DN 80 PN 40
DN 100/125/150/200 PN 16
DN 250 and above PN 10

TSK1-S
DN 50/80 PN 40
DN 100/125/150/200 PN 16
DN 250 and above PN 10

TSK1-K / TSK1-P
DN 50/100 PN 16
DN 125/150/200 PN10
DN 250 and above PN 6

7.3.4 Inlet and outlet sections

The standard inlet section must be 5 x D and the standard
outlet section 3 x D. For an extremely non-linear flow profile
(e.g. shut-off/control valves or tee inlet units are located in
front of the meter), we recommend doubling the inlet section
or using flow straighteners.
