B-4 Accusonic Model 8510+ Series Flowmeter
For removable transducers (Models 7600, 7601, 7635, 7620), remove the unit according to the procedures
recommended by Accusonic, and then clean, inspect, and possibly replace the unit.
DANGER: Removing a transducer from a pressurized pipe MUST be done in strict accordance
with Accusonic procedures. Failure to do so may result in serious injury to personnel or in damage
to the transducer or other equipment nearby.
Note: Transducers are position-dependent. When replacing a transducer, always verify that the
replacement unit is of the same type as the unit removed. In particular, pay attention to the angle,
position, and length designators (i.e., 45°,60°,65°; inner vs. outer; Short or Long) that are part of
the model and serial number designators marked on the body of the unit.

7601 Series Transducers

The transducers are installed in special feedthroughs which allow for removal of the transducer without
dewatering the pipe or disturbing the alignment of the unit. A special tool must be used. The following is a
step-by-step procedure for removal, cleaning, and reinsertion of the transducer.
DANGER:
PRESSURE FROM THE LIQUID IN THE PIPE. ANY ATTEMPT TO REMOVE A
TRANSDUCER IN ANY OTHER MANNER THAN OUTLINED BELOW MAY
CAUSE SERIOUS INJURY TO PERSONS IN THE GENERAL AREA.
Caution: The 7601 transducers are equipped with a gauge for confirming that the locking pin is
fully engaged. Measurements with the gauge and an independent test is required to confirm that
the locking pin is seated. If the gauge is missing, do not proceed. Never loosen the locking pin
unless the transducer removal tool supplied by Accusonic is installed in complete accordance with
the procedure given below.
