liquid, thus resulting in incorrect read-
ings, which results in an overstatement
of actual flowrate and volume. This
condition can damage the flowmeter.
WARNING
If liquid being measured contains
large solids, install a filter or strainer.
Without the use of a filter or strainer,
damage can occur to the internal
components.
In process lines where particulates
are present, a filter/strainer should be
used. Refer to the table below for the
recommended mesh size.

MAINTENANCE
Disassembling the Turbine
1. Disconnect the output cable from
the magnetic pickup (See 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. Insert a small screwdriver or similar
tool, into the radius notch of the
retaining ring, pull away from the
groove and up, removing the re-
taining 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 sup-
port.

A replacement kit is comprised of all

the internal component parts within
the turbine flowmeter. A replacement
kit consists of the following:
*
GPI supports are identical in design,
thus eliminating assembly error. Each
support incorporates a thrust bearing,
which allows for bidirectional flow and
prevents damage to the rotor and/
or supports in the event the turbine
flowmeter is installed backwards with
respect to the direction of flow.
simply repeat this operation.
apart, inspect the turbine flowmeter
body for signs of wear or defects.
The body bore should be smooth
and show no evidence of wear.
