2 RADIATED MICROWAVES The instrument antenna sends tight electromagnetics pulses on base band 6 GHz (C-band). These pulses are irradiated and then reflected, from the product surface to be measured and received back by the same antenna. A method of time elongation, allows the assessment of the time of fl ight which, by its nature, is particularly short, to be able to calculate with accurancy the distance and hence the level of the product to be measured. Dust, vapors, high temperatures and pressures are well tolerated and allow the use of units in critical conditions. An advanced computerized system by envelope curve and the possibility to map the false echo curve allow to improve the measurement in critical conditions. Thanks to the two-wire technology (2-wire) and HART communication makes the installation, the commissioning and the use of the units is very simple and intuitive.

These pulses are irradiated by antenna and then refl ected, at least in part, from the surface of the product to be measured and received back by the same antenna. A method of time elongation, allows the assessment of the time of flight which, by its nature, is particularly short, to be able to calculate with accurancy the distance and hence the level of the product to be measured. The K-band, with a frequency of electromagnetic waves of 26 GHz, allows the detection of the products surface whose dielectric constant is low.on the other hand it is not advisable to use in the presence of water vapor or conductive or damp dusts

The echo comes back to the same rope and is detected as a surface of the product.

22 GUIDED MICROWAVES A short electromagnetic pulse is sent along a rope and is refl ected back once it reaches its end. If the rope is immersed into the product to be measured, in the point of contact air/product an echo is generated by this discontinuity. The echo comes back to the same rope and is detected as a surface of the product. A method of time elongation, allows the assessment of the time of fl ight which, by its nature, is particularly short, to be able to calculate with accurancy the distance and hence the level of the product to be measured. These are particularly suitable for use with powders, granules, bulk solids such as plastic chips in high and narrow silos, as well as in the food industry because these instruments do not require new calibrations when changing the type of product.

The instrument generates the high frequency pulses through a probe. The pulses are refl ected by the product surface, detected by the internal receiver and converted by microprocessor into level data. The measurement technique, coupled with the EchoDiscovery management system, and the versatility of the RWL series allows the units to be used in severe process conditions with a variety high temperature, high pressure and low dielectric constant.
