Notes on use

1 Notes on use

You have various options for accessing the descriptions of instrument functions or how to enter parameters.

1.1 Using the table of contents to locate a function description

All the functions are listed in the table of contents sorted by function group (e. g. "basic setup", "safety settings", etc.). You can access a more detailed description of a function by using a page reference.

The table of contents is on page 3.

1.2 Using the graphic of the function menu to locate a function description

This guides you step by step from the highest level, the function groups, to the exact function description you require.

All the available function groups and instrument functions are listed in the table (see page 11). Select your required function group or function. You can access an exact description of the function group or function by using a page reference.

1.3 Using the index of the function menu to locate a function description

To simplify navigation within the function menu, each function has a position which is shown in the display. You can access each function via a page reference in the function menu index (see page 73) which lists all the function names alphabetically and numerically.

Notes on use

1.4 General structure of the operating menu

The operating menu is made up of two levels:

• Function groups (00, 01, 03, …, 0C, 0E): The individual operating Selection of the instrument are split up roughly into different function groups. The function groups that are available include, e. g.: "basic setup", "safety settings", "output", "display", etc.

• Functions (001, 002, 003, …, 0E2, 0E3): Each function group consists of one or more functions. The functions perform the actual operation or parameterisation of the instrument. Numerical values can be entered here and parameters can be selected and saved. The available functions of the "basic setup" (00) function group include, e. g.: "tank shape" (002), "medium property" (003), "process cond." (004), "empty calibr." (005), etc.

If, for example, the application of the instrument is to be changed, carry out the following procedure:

1. Select the "basic setup" (00) function group.

2. Select the "tank shape" (002) function (where the existing tank shape is selected).

1.4.1 Identifying the functions

For simple orientation within the function menus (see page 11 ff.), for each function a position is shown on the display.

function group

The first two digits identify the function group:

• basic setup 00

• safety settings 01

• temperature 03

…

The third digit numbers the individual functions within the function group:

• basic setup 00  • tank shape 002

• medium property 003

• process cond. 004 …

Hereafter the position is always given in brackets (e. g. "tank shape" (002)) after the described function.

manual

If the level is not proportional to the volume or weight within the set measuring range, you can enter a linearisation table in order to measure in customer units. The requirements are as follows:

• The 32 (max.) value pairs for the linearisation curve points are known.

• The level values must be given in ascending order. The curve is monotonously increasing.

• The level heights for the first and last points on the linearisation curve correspond to empty and full calibration respectively.

• The linearisation takes place in the basic setup unit ("distance unit" (0C5)).

DOCT-0843A 01/2010 185572

Each point (2) in the table is described by a value pair: level (3) and, for example, volume (4). The last value pair defines the 100 % output (= 20 mA for HART).

Note!

The manual linearisation mode can also be used for flow measurements. To do this, simply enter the respective flow level (instead of the volume) into the table. You can find the appropriate flow values in the Q/h table of your channel or weir.

If the actual distance is not known, no mapping can be carried out.

manual

A mapping is also possible by manual entry of the range to be suppressed. This entry is made in the "range of mapping" (052) function.

Caution!

The range of mapping must end 0.5 m (20 in) before the echo of the actual level. For an empty tank, do not enter E, but E - 0.5 m (20 in).

7.3 Function "range of mapping" (052)

7.7 Function "echo quality" (056)



The echo quality is the benchmark for measurement reliability. It describes the amount of reflected energy and depends primarily on the following conditions:

• Surface characteristics (waves, foam etc.)

• Distance between sensor and product

Low values increase the probability that the echo is lost through a change in measurement conditions, e. g. turbulent surface, foam, large measuring distance.



This function corrects the measured level by a constant value. The entered value is added to the measured level.

7.9 Function "output damping" (058)

14.1 Envelope curve

The echo of an ultrasonic impulse does not only contain the desired echo from the product surface, but also interference echoes (e. g. from tank fittings or multiple reflections). In order to identify these echoes one plots the logarithmic amplitude of the echo versus the time-of-flight of the ultrasonic impulse. This plot is called envelope curve.

The envelope curve can be displayed in the "envelope curve" (0E) function group (see page 48).

14.2 Interference echo suppression (tank mapping)

The interference echo suppression of the LUC-M** makes sure that interference echoes are not interpreted as the level echo by fault.

In order to carry out the interference echo suppression one must record a time-of-flight dependent threshold (TDT), which is also called the tank map. All maxima of the envelope curve which are situated below the TDT are discarded by the signal evaluation procedures.

It is recommended to record the tank map when the vessel is as possible empty. Then, the map will include all echoes except the level echo.

But even, if it is not possible to empty the vessel during the commissioning of the LUC-M**, you should perform the map. In this case it is recommended to repeat the record of the mapping at a later time – when the vessel is as possible empty.

The tank map is recorded in the function group "extended calibration" (05). Select the option "mapping" in the "selection" (050) function.

14.3 Floating Average Curve (FAC)

The function of the Floating Average Curve (FAC) is similar to the interference echo suppression.

The main difference is, that the tank map is recorded only once whilst the FAC adjusts itself continuously to the changing measuring conditions.

By this procedure changes of the interference echoes (e. g. by build-up) can be compensated for.

In contrast to the tank map, the FAC can only register small interference echoes.

The FAC is always used in the signal evaluation, even if the tank map has been deactivated.

In the envelope curve, the maximum with the largest distance to the FAC is interpreted as the level echo.
