* Cleaning, inspecting and/or replacing parts can be done by following the procedure below.*
Read the entire procedure before taking apart the meter. Be careful when handling parts!
1) Remove the sensor (1) from the meter by loosening the
3 set screws (2c) with a 3mm hex key.
2) Remove the Sensor Adapter (2a), by removing the M4
Screws (2b).
3) Loosen the Socket Cap Screws (3) from the nuts (12)
by using a 5mm hex key for the bolts and a 10mm
socket for the nuts. Also, remove the spring washers
(4) and flat washers (5).
4) Separate the upper and lower housings (6) & (11).
Insert 2 hex keys or similar tools into the 2 holes (*).
Using a small hammer and holding the upper housing,
lightly tap the hex keys to separate the housings.
Alternate tapping the hex keys to avoid damage to the
locating pin holes. **DO NOT use a
screwdriver or other tools to pry apart
the housings as this can cause permanent
damage to the flow meter bodies and
internal parts and will void the
warranty.**
5) Once the housings are separated:
a. Remove the gears (8). Inspect the gears and
clean if needed. Be careful not to drop the
gears as this will damage them.
b. Remove the shafts (7), inspect them and clean
them if needed.
c. Clean out the cavity in the upper and lower
housings and inspect them for damage and/or
wear.
d. Replacing the PTFE o-ring (9) is
recommended to ensure sealing once
reassembled.
6) To reassemble the meter:
a. Insert the o-ring (9) into the o-ring groove.
b. Insert the shafts (7) back into the shaft holes.
c. Insert the gears back into place. Make sure
they are able to freely spin.
d. Rejoin the upper and lower housings together,
using the locating pins (10) to guide the
positioning of the housings.
e. Reinsert the bolts, washers and nuts. Torque
down bolts to 3.5 ft/lbs. (See diagram on
next page for recommended order to
tighten bolts.)
f. Reinstall the sensor adapter (2) and sensor (1).
Do Not Over Tighten the screws (3) as you
can strip the threads in the meter body.
