Transducers replacement

This section discusses replacing the transducers for direct mount and remote mount
electronics options specific to your meter size (2" - 3", 4" - 10", and 12" and larger
meters).
Tip
Liquid transducer capsules can be replaced a single transducer capsule at a time. They do
not need to be replaced in pairs. Average delay and delta times are based on the
transducer housing so they will not change in the meter configuration when transducer
capsules are replaced.
WARNING
CUTTING HAZARD
Sharp edges may be present on the meter.
Wear appropriate personal protective equipment when working on the meter.
Failure to comply may cause serious injury.
WARNING
FLUID CONTENTS MAY BE UNDER PRESSURE
When the meter is under pressure, DO NOT attempt to remove or adjust the transducer
housing.
Attempting to do so may release pressurized fluid, resulting in serious injury for personnel
or equipment damage.
