3.3 Transducer holder removal and installation
WARNING!
CONTENTS MAY BE UNDER PRESSURE
When the meter is under pressure, DO NOT attempt to remove or adjust the transducer holder.
Attempting to do so may release pressurized gases, resulting in serious injury or equipment
damage.
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.
3.3.1 Remove the transducer holder
Daniel 3410 Series Ultrasonic Gas Flow Meters utilize transducer holders that contain the
transducer assemblies and act as the pressure barrier between the transducers and the
fluid. Under normal maintenance such as transducer replacement, the transducer holders
do not need to be removed. If it is necessary to remove the transducer holders, the
Meter repairs
