Reference manual
The flow sensor contains two magnetic coils located on opposite sides of the sensor. Two
electrodes, located perpendicular to the coils and opposite each other, make contact with
the liquid. The transmitter energizes the coils and creates a magnetic field. A conductive
liquid moving through the magnetic field generates an induced voltage at the electrodes.
This voltage is proportional to the flow velocity. The transmitter converts the voltage
detected by the electrodes into a flow reading. A cross-sectional view is show in Figure 2-6.

3.1 Handling and Lifting Safety
CAUTION
To reduce the risk of personal injury or damage to equipment, follow all lifting and
handling instructions.
• Handle all parts carefully to prevent damage. Whenever possible, transport the
system to the installation site in the original shipping container.
• 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.
• Keep the shipping plugs in the conduit ports until you are ready to connect and seal
them. Appropriate care should be taken to prevent water ingress.
• The sensor should be supported by the pipeline. Pipe supports are recommended on
both the inlet and outlet sides of the sensor pipeline. There should be no additional
support attached to the sensor.
• Use proper PPE (Personal Protection Equipment) including safety glasses and steel
toed shoes.
• Do not lift the meter by holding the electronics housing or junction box.
• 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.
• Do not drop the device from any height.
3.2 Location and Position
3.2.1 Environmental considerations
To ensure maximum transmitter life, avoid extreme temperatures and excessive vibration.
Typical problem areas include the following:
• High-vibration lines with integrally mounted transmitters
• Tropical/desert installations in direct sunlight
• Outdoor installations in arctic climates
Reference manual 13
Sensor Installation Reference manual

Remote mounted transmitters may be installed in the control room to protect the
electronics from the harsh environment and to provide easy access for configuration or
service.
3.2.2 Upstream and downstream piping
To ensure specified accuracy over widely varying process conditions, install the sensor
with a minimum of five straight pipe diameters upstream and two pipe diameters
downstream from the electrode plane.
Figure 3-1: Upstream and downstream straight pipe diameters
3.2.3
A. Five pipe diameters (upstream)
B. Two pipe diameters (downstream)
C. Flow direction
Installations with reduced upstream and downstream straight runs are possible. In
reduced straight run installations, the meter may not meet accuracy specifications.
Reported flow rates will still be highly repeatable.
Flow direction
The sensor should be mounted so that the arrow points in the direction of flow.

Reference manual Sensor Installation
00809-0500-4444 May 2019
3.2.4 Sensor piping location and orientation
The sensor should be installed in a location that ensures it remains full during operation.
Depending on where it is installed, orientation must also be considered.
• Vertical installation with upward process fluid flow keeps the cross-sectional area full,
regardless of flow rate.
• Horizontal installation should be restricted to low piping sections that are normally full.
Figure 3-3: Sensor orientation
3.2.5
A. Flow direction
Electrode orientation
The electrodes in the sensor are properly oriented when the two measurement electrodes
are in the 3 and 9 o’clock positions or within 45 degrees from the horizontal, as shown on
the left side of Figure 3-4. Avoid any mounting orientation that positions the top of the
sensor at 90 degrees from the vertical position as shown on the right of Figure 3-4.

Figure 3-4: Electrode orientation
A. Correct orientation
B. Incorrect orientation
The sensor may require a specific orientation to comply with Hazardous Area T-code
rating. Refer to the appropriate reference manual for any potential restrictions.
3.3 Sensor Installation
3.3.1 Flanged sensors
Gaskets
The sensor requires a gasket at each process connection. The gasket material must be
compatible with the process fluid and operating conditions. Gaskets are required on each
side of a grounding ring (see Figure 3-5). All other applications (including sensors with
lining protectors or a grounding electrode) require only one gasket on each process
connection.
Note
Metallic or spiral-wound gaskets should not be used as they will damage the liner face of
the sensor. If spiral wound or metallic gaskets are required for the application, lining
protectors must be used.

B. Customer-supplied gasket
Bolts
Note
Do not bolt one side at a time. Tighten both sides simultaneously. Example:
1. Snug upstream
2. Snug downstream
3. Tighten upstream
4. Tighten downstream
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 3-2 for ASME
B16.5 flanges and Table 3-3 or Table 3-4 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 3-6 to 20% of the suggested torque values.
Repeat the process on the downstream side of the sensor. For sensors with greater or
fewer flange bolts, tighten the bolts in a similar crosswise sequence. Repeat this entire
tightening sequence at 40%, 60%, 80%, and 100% of the suggested torque values.
If leakage occurs at the suggested torque values, the bolts can be tightened in additional
10% 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
Reference manual 17
Sensor Installation Reference manual
May 2019 00809-0500-4444
liner often leads 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. While under pressure, sensor materials
may deform over time and require a second tightening 24 hours after the initial
installation.

Studs
Wafer sensors require threaded studs. See Figure 3-8 for torque sequence. Always check
for leaks at the flanges after tightening the flange bolts. All sensors require a second
tightening 24 hours after initial flange bolt tightening.

Installation
1. Insert studs for the bottom side of the sensor between the pipe flanges and center
the alignment spacer in the middle of the stud. See Figure 3-7 for the bolt hole
locations recommended for the spacers provided. Stud specifications are listed in
Table 3-6.
2. Place the sensor between the flanges. Make sure the alignment spacers are properly
centered on the studs. For vertical flow installations slide the o-ring over the stud to
keep the spacer in place. See Figure 3-7. Ensure the spacers match the flange size
and class rating for the process flanges. See Table 3-5.
3. Insert the remaining studs, washers, and nuts.
4. Tighten to the torque specifications shown in Table 3-7. Do not over-tighten the
bolts or the liner may be damaged.

3.3.3 Sanitary senors
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.
Note
Gaskets are supplied between the IDF fitting and the process connection fitting, such as a
Tri-Clamp fitting, on all Rosemount 8721 Sanitary sensors except when the process
connection fittings are not supplied and the only connection type is an IDF fitting.
Alignment and bolting
Standard plant practices should be followed when installing a magmeter with sanitary
fittings. Unique torque values and bolting techniques are not required.

B. User supplied gasket
3.4 Process reference connection
The figures shown in this section illustrate best practice installations for process reference
connections only. For installations in conductive, unlined pipe it may be acceptable to use
one ground ring or one lining protector to establish a process reference connection. Earth
safety ground is also required as part of this installation, but is not shown in the figures.
Follow national, local, and plant electrical codes for safety ground.
Use Table 3-8 to determine which process reference option to follow for proper
installation.

Sensor Installation
4.1 Pre-Installation
Before installing the transmitter, there are several pre-installation steps that should be
completed to make the installation process easier:
• Set the hardware switches if necessary
• Consider mechanical, electrical, and environmental requirements
Note
Refer to Product Specifications for more detailed requirements.
Hardware switches
The electronics board is equipped with two user-selectable hardware switches. These
switches set the Simulate Enable and Transmitter Security. The standard configuration for
these switches when shipped from the factory are as follows:
Table 4-1: Hardware switch default settings
Setting Factory configuration
Simulate enable Off
Transmitter security Off
In most cases, it is not necessary to change the setting of the hardware switches. If the
switch settings need to be changed, refer to Hardware switches.
Be sure to identify any additional options and configurations that apply to the installation.
Keep a list of these options for consideration during the installation and configuration
procedures.
Mechanical considerations
The mounting site for the transmitter should provide enough room for secure mounting,
easy access to conduit entries, full opening of the transmitter covers, and easy readability
of the Display screen (if equipped).
