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.
