applications
(1) Not in fully submerged applications.
(2) For overall level applications a changing dielectric has no effect on the measurement. For interface measurements a
changing dielectric of the top fluid will degrade the accuracy of the interface measurement.
(3) See Table A-2 for more information.
(4) See Table A-1 for more information.
(5) Ok If probe is anchored.
(6) Not suitable in applications with disturbing EMC from nearby equipment.
