Difference between radiation type level measurement and capacitive type level measurement

There is difference between radiation type level measurement and capacitive type level measurement  is given below.

Radiation type level measurement Capacitive type level measurement
The Radiation type level measurement is suitable for level measurement of hot liquid metal. The capacitive type level measurement is suitable for level measurement of slurries.
It works on the principle of absorption of β and ϒ rays. It works on the principle of change in capacitance due to change in dielectric constant.
External radiation may affect the measurement. Performance is affected by dirty liquid.
Temperature does not affect in this measurement. Temperature may affect in this measurement.
It relatively expansive. It cost is low.
