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.
