Level measuring by guided EM pulse

Direct electromagnetic radiation method allows to measure liquid indicator, the level for friable hard materials, intermediate stage substance in aggressive environments, extended temperature and pressure variation range in the low dielectric constant of a control product. The article reports on the method's physical properties, as well as its comparison with ultrasonic and non-contact radar methods. The level meters "Pulscon" are described as an example of sensors, which implement the direct electromagnetic method. Practical recommendations on microwave level measuring sensors applications are made.
