will cause the rotor to spin at a faster
rate than liquid, thus resulting in in-
correct readings, which results in an
overstatement of actual flowrate and
volume. This condition can damage
the flowmeter.
In process lines where particulates
are present, a filter/strainer should
be used. Refer to the table below for
the recommended mesh size.

WARNING
If liquid being measured by
sleeved bearing turbine flowme-
ters contains large solids, install a
filter or strainer. Without the use
of a filter or strainer, damage can
occur to the internal components.

MAINTENANCE
Disassembling the Turbine
1. Disconnect the turbine flowmeter
cable from the magnetic pickup.
Refer to Figure 1.
2. Remove the magnetic pickup.
3. Ensure that the process line is
depressurized and empty prior to
removal of the turbine flowmeter.
Remove the turbine flowmeter from
the process line.
4. Using a small screwdriver or similar
tool, insert it into the radius notch
of the retaining ring, pull away from
the groove and up, removing the
retaining ring from one end of the
turbine flowmeter. This will allow
the support to slide out of the
turbine flowmeter body. Remove
the rotor before proceeding to the
other support.
NOTE: To remove the other support,
simply repeat this operation.
