2.5 Installation guidelines
Choosing the correct installation
location for the RIM10 involves several
important considerations:
Ambient temperature limit
The electronics are designed to
function in a maximum continuous
ambient temperature of 60°C (140°F).
If the ambient temperatures exceed
this the electronics should be remotely
mounted.
Upstream / downstream pipework
The installation location should
be selected to minimize possible
turbulence and swirl. The extent of
ow disturbances depends upon the
conguration of the piping. Valves,
elbows, control valves and other
piping components that may add
disturbances to the ow. If such
conditions exist and/or sufcient
straight pipe is unavailable, a ow
conditioner may be used to improve
measurement conditions. The
minimum straight run requirements
for different piping congurations are
shown in Figure 2.
Please note that the straight run of
pipe must have the same nominal
diameter as the owmeter body.

3. Mechanical installation
3.1 Pipe tapping
The pipeline should be prepared for either cold tap or hot tap installations. A cold tap
installation involves drilling a hole into a pipeline that has been depressurised and for
which service has been shutdown. A hot tap installation involves drilling a hole into a
pressurised line without line shutdown and disruption of the process.
The RIM10-600 and RIM10-900 rotor insertion owmeters can be hot or cold tapped.
Fig. 4 RIM10-600
Fig. 5 RIM10-900
The RIM10-700 rotor insertion flowmeter can only be cold tapped (it must not be
hot tapped); it can only be installed and removed with process shutdown because
it uses a Swagelok® fitting.

3.2 RIM10-600 and RIM10-900 hot tap and cold tap installation
3.2.1 Hot tap installation: M-TMP-600 and M-TMP-900
Caution - Risk of danger: Hot tap installation must only be done by qualied personnel.
The RIM10-600 and RIM10-900 can be installed without process shutdown or line
depressurisation. The RIM10-600 is shipped with an isolation valve and a pipe nipple
attached to the owmeter - See Figure 6. For a hot tap installation, the isolation valve and
pipe nipple need to be separated from the owmeter. Use Steps 1 to 5 as a guide.

3.2.3 Insertion depth scale reading calculation
After tapping the pipe and installing the RIM10 owmeter, the turbine sensor needs to be
properly positioned within the pipe. To determine the proper insertion depth, the scale
reading must be calculated. The scale reading is the gure that the top of the cursor should
be set to on the depth scale. Use the correct side of the scale depending on the rotor type:
- For the L1 and G1 - G5 rotors use the left-hand side of the scale.
- For the G6 rotor uses the right-hand side of the scale.
Insertion depth calculation for the RIM10-600 and RIM10-900 Series
Use the following equation to calculate the insertion depth for M-TMP 600 / 900 series:
Scale reading = I + E + Wt
Where:
I = For pipe sizes less than 300 mm (12"), inside pipe diameter ÷ 2.
I = For pipe sizes 300 mm (12") and larger, inside pipe diameter ÷ 4.
E (for the RIM10-600) = Distance from the top of the stem housing to the outside pipe
wall. This distance varies depending on how tightly the pipe nipples are screwed into the
isolation valve and thread-o-let.
E (for the RIM10-900) = Distance from the top of the isolation valve to the outside pipe wall.
Wt = Thickness of the pipe wall. The disk cut-out or 'coupon' from the tapping procedure
can be measured, or this number can also be obtained from a piping handbook.
Example:
A RIM10-600 150 Rotor is to be installed on a 300 mm (12") Schedule 40 pipe. The
following measurements have been obtained:
Metric:
I = 303.2 ÷ 4 = 75.8 mm
E = 317.5 mm
Wt = 10.3 mm
Scale reading (B) = 75.8 + 317 + 10.3 = 403.6
Imperial:
I = 11.938 ÷ 4 = 2.98
E = 12.5
Wt = 0.406 300 mm (12") Schedule 40
Scale reading (B) = 2.98 + 12.5 + 0.406 = 15.9
Use the retractor handle to carefully insert
the rotor down into the pipe until the
calculated insertion depth gure on the
depth scale lines up with the top of the
cursor. The depth scale is set to read in
inches and is in ratio based on its position
in relation to the stem.
Align the retractor bar assembly so that the
ow direction arrow on the cursor is in line
with the pipe and pointing downstream.

Caution: Do not allow the orientation of the flowmeter or the insertion depth to
change after insertion is complete. A change in insertion depth or alignment will
cause inaccurate readings and shortened rotor life.

3.2.4 Rotor orientation and final positioning
Note: Tighten the nuts above the packing gland to 34 N m (25 lbf ft) to stop leakage around
the stem. Do not over tighten!
Caution: Do not allow the orientation of the owmeter or the insertion depth to change
after insertion is complete. A change in insertion depth or alignment will cause inaccurate
readings and shorten rotor life.
Step 1 - Carefully insert the rotor into the pipe until the calculated scale reading on
the depth scale lines up with the arrow on the retractor bar assembly. If the
rotor is a 38 mm (1.5") size (RIM10-600 with ASME [ANSI] Class 150 anged
connection), line up the bottom arrow on the retractor bar assembly marked 1.5
with the depth scale as shown in Figure 10.
Step 2 - Align the rotor by using the orientation lever so the ow direction arrow is in line
with the pipe and pointing downstream.
Step 3 - Tighten the nuts above the packing gland to 34 N m (25 lbf ft) to stop leakage
around the stem. Do not over tighten!
Step 4 - Lock the stem in position by tightening the orientation lock screw.

3.2.5 Rotor orientation and final positioning
Use the retractor handle to carefully insert the rotor down into the pipe until the calculated
insertion depth gure on the depth scale lines up with the top of the cursor. Use a pipe
wrench to align the retractor bar assembly so the ow direction arrow on the cursor is in
line with the pipe and pointed downstream. Lock the stem in position by tightening the
orientation set screw - See Figures 11 and 12.
Caution: Do not allow the orientation of the owmeter or the insertion depth to change
after insertion is complete. A change in insertion depth or alignment will cause inaccurate
readings and shorten rotor life.

For L1 and G1 to G5 rotors 368 mm (14.50")
I = For pipe sizes less than 300 mm (12"), inside pipe diameter ÷ 2
For pipe sizes 300 mm (12") and larger, inside pipe diameter ÷ 4
E = Distance from the raised face of the ange or top of the screwed tting to the outside
pipewall.
Wt = Thickness of the pipe wall. The disk cut-out or 'coupon' from the tapping procedure
can be measured, or this number can also be obtained from a piping handbook.
Example:
An RIM10-700 with a G6 rotor is to be installed on a 300 mm (12") Schedule 40 pipe. The
following measurements have been obtained:
C = 362 mm (14.25")
I = 303.2 ÷ 4 = 75.8 mm (11.938" ÷ 4 = 2.98)
E = 114.3 mm (4.5")
Wt = 10.3 mm (0.406" 12" Schedule 40)
B = C-I- E-Wt = 362 - 75.8 - 114.3 - 10.3 = 161.6 mm (14.25" - 2.98" - 4.5" - 0.406" = 6.364")
Manually insert the stem into the pipe until the calculated insertion depth is obtained. Align
the rotor by using the orientation levers so that the ow direction arrow is parallel to the pipe
and pointing downstream.
Lock the stem in position by tightening the Swagelok® tting. Verify insertion depth prior
to nal tightening of the tting. When the tting has been tightened, the stem position
becomes permanent and cannot be changed.
