5 Maintenance
5.1 Overview
The design of the transmitter uses electromagnetic impulses guided along a metallic probe
and time domain reflectometry to measure distance to measured material and convert it into
level indication. Because there are no moving parts, the maintenance of the transmitter is
greatly reduced in comparison with historic level measurement devices.
5.2 Preventive Maintenance Practices and Schedules
If the transmitter is installed in contact with a sticky or viscous medium, a periodic cleaning
may be required. The frequency of cleaning should be adjusted based on application needs
and visual inspection.
