IMPORTANT NOTICE
This document provides basic installation guidelines for the Rosemount®8700 Series
Sensors. It does not provide instructions for detailed configuration, diagnostics,
maintenance, service, troubleshooting, explosion-proof, flameproof, or intrinsically safe
(I.S.) installations. Refer to the Rosemount 8700 reference manual (document number
00809-0100-4727) for more instructions. The manual and this QIG are also available
electronically on www.rosemount.com.
WARNING
Failure to follow these installation guidelines could result in death or serious
injury:
Installation and servicing instructions are for use by qualified personnel only. Do not
perform any servicing other than that contained in the operating instructions, unless
qualified. Verify that the operating environment of the sensor and transmitter is consistent
with the appropriate FM, CSA, ATEX, or IECEx approval.
WARNING
The sensor liner is vulnerable to handling damage. Never place anything through the
sensor for the purpose of lifting or gaining leverage. Liner damage can render the sensor
useless.
To avoid possible damage to the sensor liner ends, do not use metallic or spiral-wound
gaskets. If frequent removal is anticipated, take precautions to protect the liner ends.
Short spool pieces attached to the sensor ends are often used for protection.
Correct flange bolt tightening is crucial for proper sensor operation and life. All bolts must
be tightened in the proper sequence to the specified torque limits. Failure to observe
these instructions could result in severe damage to the sensor lining and possible sensor
replacement.
WARNING
Rosemount 8705 Magnetic Flowtube units ordered with non-standard paint options may
be subject to electrostatic discharge.
To avoid electrostatic charge build-up, do not rub the meter body with a dry cloth or clean
with solvents.

STEP 1: HANDLING
Handle all parts carefully to prevent damage. Whenever possible, transport the system to
the installation site in the original shipping containers. PTFE-lined sensors are shipped with
end covers that protect it from both mechanical damage and normal unrestrained distortion.
Remove the end covers just before installation.

STEP 2: MOUNTING
Upstream/Downstream Piping
To ensure specification accuracy over widely varying process conditions, install the sensor a
minimum of five straight pipe diameters upstream and two pipe diameters downstream from
the electrode plane (see Figure 2).
Installations with reduced straight runs from 0 to five pipe diameters are possible. In reduced
straight pipe run installations, performance will shift to as much as 0.5% of rate. Reported
flow rates will still be highly repeatable.
Flow Direction
The sensor should be mounted so the FORWARD end of the flow arrow, shown on the
sensor identification tag, points in the direction of flow through the sensor.

Sensor Location
The sensor should be installed in a location that ensures the sensor remains full during
operation. Vertical installation allows upward process fluid flow and keeps the
cross-sectional area full, regardless of flow rate. Horizontal installation should be restricted
to low piping sections that are normally full.
Sensor Orientation
The electrodes in the sensor are properly orientated when the two measurement electrodes
are in the 3 and 9 o’clock positions or within 45° from the vertical, as shown on the right of
Figure 4. Avoid any mounting orientation that positions the top of the sensor at 90° from the
vertical position as shown on the left of Figure 4.

STEP 3: INSTALLATION
Flanged Sensors
Gaskets
The sensor requires a gasket at each of its connections to adjacent devices or piping. The
gasket material selected must be compatible with the process fluid and operating conditions.
Metallic or spiral-wound gaskets can damage the liner. Gaskets are required on each side of
a grounding ring. All other applications (including sensors with lining protectors or a
grounding electrode) require only one gasket on each end connection.
Flange Bolts
NOTE
Do not bolt one side at a time. Tighten each side simultaneously. Example:
1. Snug left
2. Snug right
3. Tighten left
4. Tighten right
Do not snug and tighten the upstream side and then snug and tighten the downstream side.
Failure to alternate between the upstream and downstream flanges when tightening bolts
may result in liner damage.
Suggested torque values by sensor line size and liner type are listed in Table 1 for ASME
B16.5 and Table 2 for EN flanges. Consult the factory if the flange rating of the sensor is not
listed. Tighten flange bolts on the upstream side of the sensor in the incremental sequence
shown in Figure 6 to 20 percent of the suggested torque values. Repeat the process on the
downstream side of the sensor. For sensors with more or less flange bolts, tighten the bolts
in a similar crosswise sequence. Repeat this entire tightening sequence at 40, 60, 80, and
100 percent of the suggested torque values or until the leak between the process and
sensor flanges stop.

If leakage has not stopped at the suggested torque values, the bolts can be tightened in
additional 10 percent increments until the joint stops leaking, or until the measured torque
value reaches the maximum torque value of the bolts. Practical consideration for the
integrity of the liner often leads the user to distinct torque values to stop leakage due to the
unique combinations of flanges, bolts, gaskets, and sensor liner material.
Check for leaks at the flanges after tightening the bolts. Failure to use the correct tightening
methods can result in severe damage. Sensors require a second tightening 24 hours after
the initial installation. Over time, sensor liner materials may deform under pressure.
