1.2 Applications
1. Level measurement of liquids
OPTIWAVE 5400 C
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.
2. Volume (mass) measurement
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.

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.

Process connection sizeThe 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 positionMake sure that there are not any obstructions directly below the process
