The radar type level meter can be used for various applications since the microwave speed is not affected by temperature, pressure, change in the permittivity of the measured substance, or density modulation.
It can be used for powders, granules, liquids, slurries and viscous substances.
Change of the measured substance does not affect the measurement.
Maximum of 40 m can be measured without contact.
It can be used under vacuum, high temperature and high pressure.
The frequency when the transmitted electromagnetic wave reflects and reaches the receiver is detected. The required time is calculated from the change portion, converted into the level position, and then output. For frequency modulation, signal processing to keep linearity is programmed.
