Safety and responsibility Instruction for use

1. Safety and responsibility

1.1 Intended use

The 2260 Ultrasonic Level Transmitters are an excellent tool for the level measurement of liquids. Level
measurement technology based on the non-contacting ultrasonic principle is especially suited for
applications where, for any reason, no physical contact can be established to the surface of the material
to be measured. Such reasons may include corrosive attack by the process medium against the
measuring device material (acids), possible contamination (sewage) or particles of the process medium
adhering to the measuring device (adhesive materials).

1.2 Safety regulations for the Ex approved units

The 2260 Ultrasonic Level Transmitter must be operated in intrinsically safe circuit only, see values in
chapter “Technical Data”. For temperatures see values in “Techical Data”. Transducer head are made of
plastic tending to charge up electrostatically, thus:

 The velocity of the filling and discharging process must be chosen according to the medium.
 During filling the material causing the hazard must be hindered from forming a mist
 It is not permitted to clean the plastic cover in explosion hazardous area
 The apparatus is not suitable for flame-proof enclosure towards the external area.

2. Transport and storage

 Transport and/or store product in unopened original packaging.
 Protect product from dust, dirt, dampness as well as thermal and UV radiation.
 Make sure that the product has not been damaged neither by mechanical nor thermal influences.
 Check product for transport damages prior to the installation.

3. Design and function

3.1 Design

3

Instruction for use Design and function

3.2 Function

The ultrasonic level metering technology is based on the principle of measuring the time required for the
ultrasound pulses to make a round trip from the sensor to the level to be measured and back. The sensor
emits an ultrasonic pulse train and receives the echoes reflected. The intelligent electronic device
processes the received signal by selecting the echo reflected by the surface and calculates from the time
of flight the distance between the sensor and the surface which constitutes the basis of all output signals
of the 2260 Ultrasonic Level Transmitter.

A Total beam angle of 5°-7° at –3 dB as is featured by transducers of transmitters and sensores ensuring
a reliable measurement in narrow silos with uneven side walls as well as in process tanks with various
protruding objects.

Furthermore, as a result of the narrow beam angle - the emitted ultrasonic signals have an outstanding
focusing - deep penetration through gases, vapour and foam is ensured.

Design and function Instruction for use

Minimum measuring distance (Xm) (Dead Band) is determined by the design of the unit within which the
measurement is not possible (Dead Zone). This distance can be extended by programming in order to
avoid disturbing effects of possible disturbing echoes coming from fixed objects. (Close-end Blocking)..

Maximum measuring distance (X

) is the greatest distance (determined by the design of the unit) which

M

can be measured by the unit under ideal conditions. The maximum measuring distance of the actual
application (H) must not be greater than X

4.3 Maintenance and repair

The 2260 Ultrasonic Level Transmitters do not require maintenance on a regular basis. In some very rare
instances, however, the transducer may need a cleaning from deposited material. This must be carried
out gently, without scratching or pressing the surface of the transducer.
Repairs during or after the warranty period are carried out exclusively at the Manufacturers. The
equipment sent back for repairs should be cleaned or neutralised (disinfected) by the User.

Instruction for use Installation

5. Installation

5.1 Liquid Level Measurement

Position

The optimal position of the 2260 Ultrasonic
Level Transmitter is on the radius
r = (0.3 … 0.5) R of the (cylindrical) tank / silo.
(Take also sonic cone on page 1 into
consideration.)

Sensor alignment
The sensor face has to be parallel to the surface of the liquid
within ± 2-3°.

Temperature
Make sure that the 2260 Ultrasonic Level Transmitter will be
protected against overheating by direct sunshine.

Sonnenschirm

Obstacles
Make sure that no in-flow path or objects (e.g. cooling pipes,
ladders, bracing members, thermometers, etc.) or no tank wall of
the ragged surface protrude into the sensing cone of the
ultrasonic beam.
One fix object in the tank / silo that disturb the measurement can
be blocked out by the appropriate programming of the 2260
Ultrasonic Level Transmitters – see Parameter P29 “Blocking out
of disturbing object”

Foam
Foaming of the liquid surface may render ultrasonic level metering impossible. If possible, a location
should be found, where foaming is the least (device should be located as far as possible from liquid
inflow) or a stilling pipe or well should be used.

8

Installation Instruction for use

Stand-off-Pipe
The structure of the stand off pipe should be rigid; the inner rim where the ultrasonic beam leaves the
pipe should be rounded.

Note: The mentioned values are indications.
Depending on the assembling conditions larger
diameters are to be considered.

Wind
Intensive air (gas) movements in the vicinity of the ultrasonic cone is to be avoided. A strong draft of
wind may "blow away" the ultrasound. Devices with lower measuring frequency (40, 20 kHz) are
recommended.

Fumes/ Vapours

For closed tanks containing chemicals or other liquids, which creats fume/gases above the liquid
surface especially for outdoor tanks exposed to the sun, a strong reduction of the nominal measuring
range of the ultrasonic device is to be considered during device selection.
Devices with lower measuring frequency (40, 20 kHz) are recommended in these cases units.

Programming in general Instruction for use

6. Programming in general

The 2260 Ultrasonic Level Transmitters can be programmed by the following two ways:

1. Programming without Display Module, see 6.1

Assignment of the levels to the 4 and 20 mA current output, error indication by the analogue signal
and damping can be set.

2. With Display Module, see 6.2

All features of the unit can be set, such as measurement configuration and optimisation, 32-point
linearisation, dimensions for 11 tanks with different shape and for 21 different open channels (flume,
weir, etc).

The devices are already equipped with the display module. The 2260 Ultrasonic Level Transmitter is fully
operational without the display module. It is only needed for programming and/or displaying
measurement values.

The unit will measure during programming in accordance with the previous parameters. The new,
modified parameters will only be effective after returning to the Measurement Mode

If the 2260 Ultrasonic Level Transmitter is left in Programming Mode by mistake, it will
automatically return to Measurement Mode after 30 minutes and will operate with the
parameters entered during the last completed programming. The 2260 Ultrasonic Level

Transmitter will be delivered with the following Factory Default:

• Current output, display and bargraph: LEVEL

• 4 mA: assigned to the minimum level 0%

• 20 mA: assigned to the maximum level 100%

• Error indication by the current output: hold last value

• Damping: 60 sec

6.1 Programming without display module

Programming is only possible if the 2260 Ultrasonic Level Transmitter is in Level Measuring Mode and
receives valid echo i.e. “VALID” LED is lit. The following can be programmed without display module:

 Assignment of the 4 mA to a required e.g. min. level / max.

distance

 Assignment of the 20 mA to a required e.g. max. level /

min. distance

 Error indication by the current output (Hold, 3.6 mA or

22 mA)

 Damping (10, 30 or 60 sec)
 Reset to the factory default

Note: Current output can also be assigned in inverted mode:
4 mA = 100% (Full), 20 mA = 0% (Empty)

P04 Maximum Distance to be Measured (H)

The maximum distance to be measured is the greatest distance between the surface of the transducer
and the level to be measured.

This is the only parameter that has to be programmed for each application other than distance
(however to avoid disturbing effect of possible multiple echos it is suggested to do this in distance
measurement applications too).

Values of the maximum measuring distance will be displayed as below:

Engineering Unit Display Format

inch xxx,x

The factory programmed, greatest distances (DEFAULT values) which can be measured by the units are
listed in the table below. For the actual application the maximum distance to be measured i.e. the
distance between the sensor and the bottom of the tank should be entered in P04.
To obtain the best accuracy, measure this distance in the empty tank with the 2260 Ultrasonic Level
Transmitters by using the “GET LEVEL” function (by double key pressing of UP

+ DOWN ) provided

the bottom is flat. Enter the actual measured value displayed as P04.

The 2260 Ultrasonic Level Transmitters will not accept any echo within the

blocking distance set here.

Automatic Close-end-blocking (Automatic Dead Band control)

By using the factory default value, the unit will automatically set the smallest possible close-end­blocking distance i.e. the dead band.

Manual close-end-blocking

Manual close-end-blocking should be used for example to block out the echo originating from the bottom
rim of a stand-off pipe or from any object protruding into the ultrasonic cone near to the transmitter.
By entering a value, higher than the factory default, the minimum measuring range will be extended and
fixed to the specified value.

- Current output will hold the value corresponding to
the far end blocking level

If the medium level is above the blocked out range:

The calculation of level and volume will be based on the programmed tank dimensions, therefore the
measured or calculated process values will not be influenced in any way, by the far end blocking value.

B). Open channel flow metering

Far end blocking will be used for those small levels below which the accurate volume flow calculation is
no longer possible.

25

Instruction for use Parameters – Description and Programming

If the liquid level in the flume/weir falls below the blocked out range:

The 2260 Ultrasonic Level Transmitters will act as follows:

- Indicate ”No Flow” on the Display

- Hold last valid data on the current output.

If the level in the flume/weir is above the blocked out range:

The calculation of volume flow will be based on the programmed flume/weir data; therefore the
measurement values will not be influenced in any way, by the far end blocking value.

Factory Default: 0

7.2 Current output

P10: Value (of distance, level, volume or flow) assigned to 4 mA current output

P11: Value (of distance, level, volume or flow) assigned to 20 mA current output

Values are interpreted according to P01(a). Please note that in case of programming for (LEV or VOL) %
measurement the min and max value has to be entered in the relevant engineering units of LEV (m, ft) or
VOL (m3, ft3).

Assignment can be made so that the proportion between the change of the (measured or calculated)
process value and the change of the current output be either direct or inverse. E.g. lev 1 m assigned to
4mA and lev 10 m assigned to 20 mA represents direct proportion and lev 1 m assigned to 20 mA and lev
10 m assigned to 4 mA represents the inverse proportion.

Factory Default:

7.5 Volume Flow Measuring

7.5.1 Open Channel Flow Measurement

 For ultimate accuracy, install the sensor as close as possible above the expected maximum water

level (see minimum measuring range).

 Install the device in a place defined by the characteristics of the metering channel along the

longitudinal axis of the flume or weir.

 In some cases foam may develop on the surface. Make sure that the surface, opposite to the sensor

remain free of foam for proper sound reflection.

 From the point of view of measurement accuracy the length of the channel sections preceding and

following the measuring flume and their method of joining to the measuring channel section are
of critical importance.

 Despite of the most careful installation, the accuracy of flow metering will be lower than that of

specified for the distance measurement. It will be determined by the features of the flume or weir
applied.

P41

P47: - - - a Linearisation

Linearisation is the method of assigning requested (calibrated or calculated) level, volume or flow to
values measured by the transmitter.
It can be used for instance if the sound velocity is not known (LEVELLEVEL) or in the case of tank with
other shape than under 6.4 or open channel other than under 6.5 (LEVEL  VOLUME or LEVEL  FLOW).

7.10 Simulation

This function enables the user to test the settings of the outputs. The 2260 Ultrasonic Level Transmitters
can simulate the static or continuous change of level according to the simulation cycle time, high level
and low level set in P85, P86 and P87. (The simulation levels must be within the programmed measuring
range set in P04 and P05.)
After selecting simulation type in P85 and setting simulation values Measurement Mode has to be re­entered. While the 2260 Ultrasonic Level Transmitters is in simulation mode the DIST, LEV or VOL symbol
will be blinking. To quit Simulation Mode P84= 0 should be set.

P99: dcba Access Lock by Secret Code

The purpose of this feature is to provide protection against accidental (or intentional) re-programming of
parameters.

The Secret Code can be any value other than 0000. Setting a Secret Code will automatically be activated
when the 2260 Ultrasonic Level Transmitters is returned to the Measurement Mode. If the Secret Code is
activated, the parameters can only be viewed, this is indicated by the a flashing colon “:” between the
parameter address and the parameter value.

In order to program the device locked by a secret code, first enter the Secret Code in P99. The Secret
Code is re-activated each time the 2260 Ultrasonic Level Transmitters is returned to Measurement Mode.
To delete the Secret Code, enter the Secret Code in P99. After confirming it with [E] re-enter the
parameter P99 and enter 0000.
