Certain errors in uncompensated capacitive level gauges

  • Published:
Measurement Techniques Aims and scope

Conclusions

Variations of the permittivity and conductivity of the medium produce errors in the measurements of uncompensated capacitive level gauges. For a rapid evaluation of the maximum possible error it is advisable to use diagrams in coordinates of permittivity versus conductivity.

When a capacitive level gauge is used in a large tank, it should be placed inside a grounded conducting screen which will reduce the errors due to changes in the electrical properties of the medium. The minimum diameter of the screen is determined by a reduction in the sensitivity of the instrument, the eccentricity of the transducer with respect to the screen, and the rise in other component errors.
