Guided radar

Continuous level measurement is a very important process variable either for control, inventory or safety applications is vital information needed for your plant operation.

There are two main types of products to measure level liquids or bulks, with many different characteristics, water base, hydrocarbons, chemicals, powders, granulates, with foam presence, turbulence surface or dusty atmosphere so the selection of the correct level measurement instrument need the assistance of an expert to get the best result for your process.

Guided radar

Measurement Principle

These transmitters work base on time of flight (TOF) technology: High frequency radar emit pulses by an antenna that are reflected off the surface of the product. The time elapsed between the emission of the pulses and their return reception is the magnitude proportional to the level of the product. The difference between regular antenna radars and guided antenna is that the pulses travel through a cable or rod up to the product surface and return in order to concentrate the signal for low dialectric constant liquids or heavy dust atmosphere solids applications.
