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. |
