1.2 Applications

1. Level measurement of solids

OPTIWAVE 6400 C

The level transmitter can measure the level of a
wide range of solid 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.

2. Mass (volume) measurement

A strapping table function is available in the
configuration menu for volume or mass
measurement. Up to 50 mass (volume) values can be
related to level values. For example:
Level 1= 2 m / Mass 1= e.g. 100 kg
Level 2= 10 m / Mass 2= e.g. 500 kg
Level 3= 20 m / Mass 3= e.g. 1000 kg

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

OPTIWAVE 6400 C (24 GHz)
for solids from granulates to rocks

OPTIWAVE 6400 C

By combining high signal dynamics and FMCW radar
technology, this market-entry 24 GHz radar device
measures accurately and reliably the level of solids
like stone, plastic granulates or coffee beans. No
need for expensive antenna aiming kits or purging
systems; the proven Drop antenna design minimizes
scaling and is not affected by the angle of repose.

It operates in process conditions with temperatures
up to +130°C / +266°F and pressures up to 16 barg /
232 psig. The antenna options permit the device to
measure distances up to 100 m / 328 ft.

OPTIWAVE 6500 C (80 GHz)

low-reflective media, build-up and uneven surfaces.
The specific algorithms and high signal dynamics of
this 80 GHz FMCW radar transmitter are the key to
provide reliable and accurate readings despite these
difficult conditions. Thanks to the small beam angle
of the flush-mounted Lens antenna, this powerful
device handles high and narrow silos even in the
presence of internal obstructions.

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.

"Direct Plus" mode

"Direct Plus" mode"Direct Plus" mode
If it is possible there will be an interference signal in the measurement zone that is larger than
the level signal, select "Direct Plus" mode. If you select "Direct Plus" mode, the device locks on
the level signal and monitors changes in level. If the device then finds larger reflections in the
silo, it will only monitor the largest signal in a small search zone around the first reflection found
and ignore all other reflections. The interference signal must not be near to the level signal.

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
