Figure 1-4. Rosemount 8750W Cross Section
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.

NOTICE
The sensor liner is vulnerable to handling damage. Never place anything through the
sensor for the purpose of lifting or gaining leverage. Liner damage may render the
sensor inoperable.
Metallic or spiral-wound gaskets should not be used as they will damage the liner
face of the sensor.
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 specifications.
Failure to observe these instructions could result in severe damage to the sensor
lining and possible sensor replacement.
In cases where high voltage/high current are present near the meter installation,
ensure that proper protection methods are followed to prevent stray voltage /
current from passing through the meter. Failure to adequately protect the meter
could result in damage to the transmitter and lead to meter failure.
Completely remove all electrical connections from both sensor and transmitter
prior to welding on the pipe. For maximum protection of the sensor, consider
removing it from the pipeline.

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.
2.5.3 Mechanical considerations
The mounting site for the Rosemount 8750W should provide enough room for secure
mounting, easy access to conduit entries, full opening of the transmitter covers, and easy
readability of the LOI screen if equipped.
For remote mount transmitter installations, a mounting bracket is provided for use on a
2-in. pipe or a flat surface (see Figure 2-1 for field mount and Figure 2-3 for wall mount).
Note
If the transmitter is mounted separately from the sensor, it may not be subject to limitations
that might apply to the sensor.
Rotate integral mount transmitter housing or remote
junction box
Reference Manual
00809-0300-4750, Rev BA
The transmitter housing can be rotated on the sensor in 90° increments by removing the
four mounting screws on the bottom of the housing. Sensor lead wires should be
disconnected from the electronics before rotating the housing. Do not rotate the housing
more than 180° in any one direction. Prior to tightening, be sure the mating surfaces are
clean, the O-ring is seated in the groove, and there is no gap between the housing and the
sensor.

2.6 Handling and lifting
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 connections until you are ready to connect
and seal them.
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.
Additional safety recommendations for mechanical handling:
– Use proper PPE (Personal Protection Equipment should include safety
glasses and steel toed shoes).
– Do not drop the device from any height.
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.
If provided, use the lifting lugs on each flange to handle the Magnetic Flowmeter
when it is transported and lowered into place at the installation site. If lifting lugs
are not provided, the Magnetic Flowmeter must be supported with a lifting sling on
each side of the housing.
– Flanged sensors 3-in. through 48-in. come with lifting lugs.

2.7 Mounting
2.7.1 Upstream/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 (see Figure 2-6).

Installations with reduced upstream and downstream straight runs are possible. In reduced
straight run installations, the meter may not meet absolute accuracy specifications.
Reported flow rates will still be highly repeatable.
2.7.2 Flow direction
The sensor should be mounted so that the arrow points in the direction of flow. See Figure
2-7.

2.8 Sensor location
The sensor should be installed in a location that ensures it remains full during operation.
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.

2.8.1 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° from the horizontal, as shown on the left in
Figure 2-9. Avoid any mounting orientation that positions the top of the sensor at 90° from
the vertical position as shown on the right in Figure 2-9.

2.9 Sensor installation
2.9.1 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 2-10). 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.

2.9.2 Flange 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.
Quick Installation and Start-Up

Quick Installation and Start-Up
March 2016
Suggested torque values by sensor line size and liner type are listed in Ta b le 2- 3 for ASME
B16.5 flanges and Tab l e 2 - 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 2-11 to 20 percentof 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% 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 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. While under pressure, sensor materials may deform
over time and require a second tightening 24 hours after the initial installation.
