Turbine Insert Removal. The entire insert comes out
as a unit. After relieving all pressure inside the meter,
remove the four hex-head machine screws which hold
the insert flange in place. Lift the flange off, rocking it if
necessary to break the seal. Remove the screws which
hold the insert to the flange. If necessary, the flange
may now be reinstalled to allow restoration of pressure
in the pipe while the insert is being repaired or replaced.

Reed Sensor Removal/Installation. To install or re-
move a reed sensor, first loosen the sensor cable strain
relief. Then remove the two screws which hold the reg-
ister cap in place and unsnap and lift off the cap. Fi-
nally, lift upwards on the reed sensor to slide it out of its
dovetail slot.

To determine where to install a reed sensor, find the
pulse rate designator which corresponds to the desired
pulse rate. Start the sensor into the slot nearest the
arrow point of that designator. Start the sensor into the
slot, and push firmly until it bottoms. See photo at the
lower left.

Maintenance and Repair

Recalibration. For meters used for revenue-billing
purposes, some states require periodic calibration
checking. This type of turbine meter is most commonly
checked every four years. Testing may be done by a
local mobile meter service or in a private or municipal
meter shop. Changes in calibration should be made at
an authorized meter shop.

Register Removal. If the register must be replaced for
any reason, follow these steps:

1) Remove the register cover by taking out the two
screws which hold it in place.

2) Remove the locking ring at the base of the register
by first removing its key segment, then rotating the ring
until it comes loose.

3) Lift the register free from the meter.
