1.1 The radar solution for solids

This device is a non-contact Radar (FMCW) Level Meter for distance, level, volume, mass and reflectivity 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.

PRODUCT FEATURES

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

1.2 Options

Drop antennas

PRODUCT FEATURES

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.

Horn antennas

Use of metal horn antennas is recommended for measuring granulates, high-pressure and hightemperature 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.

PRODUCT FEATURES

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 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 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
