1.1 The radar solution for solids
This device is a non-contact Radar (FMCW) Level Meter for distance, level, volume and mass
measurement of powders, granulates and other solids. It gives a stabler measurement than
pulse radar and is well suited to dusty process conditions. The device can operate at very low and
very high process temperatures as long as the process connection temperature limits are
observed.
1 Optional touch screen with 4-button operation
2 2-wire level meter
3 Removable and rotatable converter with quick connector system
4 Stainless steel horn or PTFE/PP Drop antennas
5 Optional flange plate protection (for corrosive products) or antenna extension (for long nozzles)
6 One converter for all applications (same housing for Ex d and non-Ex)

1.2 Options
Drop antennas
Horn antennas
Drop antennas are a unique innovation to measure
powders and other solids in very dusty atmospheres.
The ellipsoidal shape of the antennas prevents
build-up and generates a small beam angle for
accurate measurement of silo contents. They have
these features:
•2 antenna sizes: DN80 or DN150.
•An installation wizard specifically for solids that
permits the instrument to measure uneven
surfaces accurately.
•Antennas can be extended to suit any nozzle length.
•Made of either PP or PTFE.
Use of metal horn antennas is recommended for
measuring granulates, high-pressure and high-
temperature applications, cement works or
processes with cyclone separators. They are
particularly resistant to mechanical shocks. They
have these features:
•Made of stainless steel 316L.
•4 antenna sizes: DN80, DN100, DN150 or DN200.
•Antennas can be extended to suit any nozzle length.

1.3 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 transmit frequency
and the receive 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 Fourier transformation (FFT) into a frequency spectrum and then the
distance is calculated from the spectrum. The level results from the difference between tank
height and measuring distance.

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 silo
(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 silo
Process connection position Make sure that there are not any obstructions directly below the process
connection for the device.
