1.2 Applications

1. Level measurement of liquids

2. Volume (mass) measurement

PRODUCT FEATURES

The level transmitter can measure the level of a
wide range of liquid products on a large variety of
installations within the stated pressure and
temperature range. It does not require any
calibration: it is only necessary to do a short
configuration procedure.

1

A strapping table function is available in the
configuration menu for volume or mass
measurement. Up to 50 volume (mass) values can be
related to level values. For example:
Level 1= 2 m / Volume 1= e.g. 0.7 m³
Level 2= 10 m / Volume 2= e.g. 5 m³
Level 3= 20 m / Volume 3= e.g. 17 m³

This data permits the device to calculate (by linear
interpolation) volume or mass between strapping
table entries.

PACTware™ software and a DTM (Device Type
Manager) is supplied free of charge with the device.
This software permits the user to easily configure
the device with a computer. It has a conversion table
function with a large number of tank shapes.

PRODUCT FEATURES

1.4 Measuring principle

A radar signal is emitted via an antenna, reflected from the product surface and received after a
time t. The radar principle used is FMCW (Frequency Modulated Continuous Wave).

The FMCW-radar transmits a high frequency signal whose frequency increases linearly during
the measurement phase (called the frequency sweep). The signal is emitted, reflected on the
measuring surface and received with a time delay, t. Delay time, t=2d/c, where d is the distance
to the product surface and c is the speed of light in the gas above the product.

For further signal processing the difference Δf is calculated from the actual transmitted
frequency and the received frequency. The difference is directly proportional to the distance. A
large frequency difference corresponds to a large distance and vice versa. The frequency
difference Δf is transformed via a Fast Fourier Transform (FFT) into a frequency spectrum and
then the distance is calculated from the spectrum. The level results from the difference between
the tank height and the measured distance.

lets the device make a selection between "Direct" mode and "TBF" mode. If the device finds a
large radar reflection above the "tank bottom area" (the bottom 20% of the tank height), the
device will use "Direct" mode. If the device finds a large radar reflection in the "tank bottom

stilling wells with a reference plate at the bottom.

Installation conditions

Process connection size The nominal diameter (DN) should be equal to or larger than the antenna diameter.

If the nominal diameter (DN) is smaller than the antenna, either:
– provide the means to adapt the device to a larger process connection on the tank
(for example, a plate with a slot), or
– use the same process connection, but remove the antenna from the device before
installation and fit it from inside the tank.

Process connection position Make sure that there are not any obstructions directly below the process

3.1 Intended use

Responsibility for the use of the measuring devices with regard to suitability, intended use and
corrosion resistance of the used materials against the measured fluid lies solely with the
operator.

The manufacturer is not liable for any damage resulting from improper use or use for other than
the intended purpose.

This radar level transmitter measures distance, level, mass, volume and reflectivity of liquids,
pastes and slurries.

It can be installed on tanks, reactors and open channels.

3.2 Pre-installation requirements

Obey the precautions that follow to make sure that the device is correctly installed.

• Make sure that there is sufficient space on all sides.

• Protect the signal converter from direct sunlight. If necessary, install the weather protection

accessory.

• Do not subject the signal converter to heavy vibrations. The devices are tested for vibration
and agree with EN 50178 and IEC 60068-2-6.

Causes of interference signals

• Objects in the tank or pit.

• Sharp corners that are perpendicular to the path of the radar beam.

• Sudden changes in tank diameter in the path of the radar beam.

Do not install the device above objects in the tank (agitator etc.) or pit. Objects in the tank or pit
can cause interference signals. If there are interference signals, the device will not measure
correctly.
If it is not possible to install the device on another part of the tank or pit, do an empty spectrum
scan. For more data, refer to the handbook.

Equipment and obstacles: how to prevent measurement of interference signals

Do not put the device immediately above equipment and obstacles in a tank or pit. This can have
an effect on the performance of the device.

If possible, do not install a nozzle on the tank centerline.

Device installation on tanks made of a non-conductive material

1 LPR equipment on a basic support (for indoor installations)
2 LPR equipment on a sealed support
3 LPR equipment on a tank made of conductive material, but with a non-conductive, sealed "window"

If the device cannot go in the tank and the tank is made of a non-conductive material (plastic
etc.), you can attach a support to the top of the tank without a hole in the tank roof. We
recommend that you put the antenna as near as possible to the top of the tank.

,

If the tank is outdoors, we recommend that you seal the support. If rain is on the top of the tank
and directly below the device, this can have an effect on the device performance.

If device is used in dusty conditions, we recommend that you seal the support. If dust is on the
top of the tank and directly below the device, this can have an effect on the device performance.

Open pits

If the device must measure the level of product in a pit, you can attach a support to the side of the
pit or above the pit.

• There is highly conductive foam in the tank.

• The liquid is very turbulent or agitated.

• There are too many other objects in the tank.

• The device is measuring a liquid (petro-chemicals) in a tank with a floating roof.

• The device is installed in a horizontal cylindrical tank.

4 Level of the liquid

•

The standpipe must be electrically conductive.

•

The inside diameter of the standpipe must not be more than 5 mm / 0.2¨ over the diameter of
the antenna (for a high-dielectric constant liquid).

•

The standpipe must be straight. There must be no sudden changes in internal diameter

¨

greater than 1 mm / 0.04

•

The standpipe must be vertical.

•

Recommended surface roughness: <±0.1 mm / 0.004¨.

•

Make sure that there are no deposits at the bottom of the standpipe.

•

Make sure that there is liquid in the standpipe.

.

You must drill an air circulation hole.

INSTALLATION

Installation in tanks containing one liquid and foam

• Drill an air circulation hole (max. Ø10 mm / 0.4¨) in the stilling well above the maximum level.

• Remove the burr from the hole.

Installation in tanks containing one liquid or more without foam

• Drill an air circulation hole (max. Ø10 mm / 0.4¨) in the stilling well above the maximum level.

• Drill 1 or more liquid circulation holes in the stilling well (if there is more than 1 liquid in the

tank).

i These holes help the liquid to move freely between the stilling well and the tank.

• Remove the burr from the hole.

Stilling wells: floating roofs

If the device must be installed on a tank with a floating roof, install it in a stilling well made of
metal.

Stilling wells: horizontal cylindrical tanks

We recommend that you install the device in a stilling well if the device:

• is for a horizontal cylindrical tank,

• is in a metallic tank,

• measures a product with a high dielectric constant and

• is on the centerline of the tank.

INSTALLATION

Figure 3-12: Horizontal cylindrical tanks

1 The device is installed without a stilling well. There are multiple reflections. Refer to the CAUTION! that follows.
2 The device is installed in a stilling well and measures correctly.

If the device is installed in horizontal cylindrical tank that contains a high dielectric constant
liquid without a stilling well, do not put it on the tank centerline. This will cause multiple
reflections and the device will not measure accurately. Use the device software to keep the
effects of multiple reflections to a minimum. For more data, refer to "Function description" in
the handbook.

4.4 Networks

4.4.1 General information

The device uses the HART® communication protocol. This protocol agrees with the HART®
Communication Foundation standard. The device can be connected point-to-point. It can also
have a polling address of 1 to 63 in a multi-drop network.

The device output is factory-set to communicate point-to-point. To change the communication
mode from point-to-point

4.4.2 Point-to-point connection
