12.1 Introduction
Sometimes it may become necessary to remove and reinstall the
sensor head. In some industries, it is common practice to rotate the
process pipes so they will wear evenly during the life of the pipe. The
following sections will describe those procedures.
12.2 Sensor Removal
WARNING
EXPLOSION HAZARD - In hazardous areas, a hot work permit
should be obtained to ensure explosive gasses are not present
in the locations where the sensor band will be handled
If removal of the sensor is required, the following procedure should be
followed.
1. Specific details regarding the removal of the passive sonar meter
should be discussed with a sales or manufacturer’s representative
prior to removal.
2. Obtain Hot Work Permit if required.
3. Turn off electrical power to the system. Follow lock-out / tag-out
procedures as required.
4. Unlatch and disconnect the sensor to transmitter cable connector
from the sensor cover. Close cable connector cover on sensor
head cover.
