Series 1406 Liquid Level Sensors - Norriseal

Series 1406
Liquid Level Sensors
Displacement Type with Torque Tube:
Offers a variety of easy-to-service designs
Series Series 1406 Liquid Level Sensor is a
versatile level sensor/torque tube used with Norriseal
liquid level controllers and transmitters. They are
available in top-mount, side-mount and externalmount
configurations.
Model 71-06-1
Top Mounted Level Sensor
Top-mounted to nozzle or flange on
a pressure vessel with displacement
element positioned inside the vessel.
For relatively quiet processes or where
a quieting chamber is located inside
the vessel.
Standard Mountings
4” Steel, Fig. -ANSI 150, 300, 400, 600
and 900. R.F. or RTJ
Displacement Element
For Fab. Steel Cage through ANSI 600:–14,
32, 48, 72, 84, 96, 108, 120. Standard
Material – Stainless Steel. Special materials
available on request.
Torque Tube. Material – Inconel,
Housing – Steel. Other materials on request.
NOTE: Level in the cage must correspond to level in
the vessel.
Features
4.0-inch ANSI class 150 through
600 raised face and ring joint
internal side mounting
Externally mounted cage with
1.5-inch and 2.0-inch thrreaded,
ANSI 150 through 600 riased face
and ring joint vessel connections
in all positions
316 SST displacer (spcial
materials on request)
Inconel torque tube
Model 71-06-2
Level Sensor with externally-
mounted cage (Stationery Head)
Externally-mounted cage housing
with stationary head. Provides a
quiet chamber for operation of displacement
element when turbulent conditions
exist inside a vessel. Permits isolation of
level controller for adjustment or repairs.
NOTE: Level in the cage must correspond
to level in the vessel.
Standard Cage Housings
11 ⁄2” or 2” Steel, Thd. – ANSI 600 or 2”

Model 71-06-3
Side Mounted Level Sensor
Side-mounted to nozzle or flange on a
pressure vessel with displacement element
positioned inside the vessel. For relatively quiet
processes or where a quieting chamber is located
inside the vessel. Also used in corrosive applications
where external piping cannot be used or
where external cage mountings are not practical
because of clogging or vapor lock.
Torque arm between displacement element and
torque tube is 20” long, double the length of top
and external mounted units. Displacement
element is correspondingly lighter and displaces
less volume.
NOTE: Special consideration must be given
to installation of long displacements through
vessel opening

Model 71-06-6
Level Sensor with externally-
mounted cage (Rotatable Head)
Externally-mounted cage housing with
rotatable head. Permits upper cage, torque
tube and controller to be rotated on the
float cage for easier accessibility as
required.
Standard Cage Housings
1 1 ⁄2” or 2” Steel, Thd. – ANSI 600 or 11⁄2” or 2”
Steel, Fig.–ANSI 150, 300, 400, 600, R.F. or RTJ
Torque Tube Assembly
Torque tube assembly consists of a shaft inside a tube. Tube is enclosed at the connector block
end, with shaft welded concentrically to end closure of the tube. At the other end, shaft rotates
in a bearing and connects to a specific gravity rocker arm. No stuffing box or packing gland
required in transmitting rotational movement from torque tube to a specific gravity rocker arm.
Torque tube is welded construction. All critical internal parts exposed to process
are either inconel or 316 stainless steel (important for corrosive services).
Displacement arm is reversible for either right or left hand
mounting of controller or transmitter. No additional parts
required for this reversal. Complete dismantling not
required. Symmetrical connector block permits
mounting of torque tube in either end.
Connector block has no bearing parts;
It’s frictionless, free from freezing or
clogging.
Principles of Operation
Displacement element is positioned in liquid to be
measured. As liquid level changes in vessel,
apparent weight of displacement element (due to
fluid displacement) varies according to amount of
its submergence. This change in weight is converted
to variable angular rotation in torque tube
and produces an output pressure from the controller
that is proportional to liquid level. Output
pressure then positions control valve to regulate
and maintain correct liquid level for process.
72-Pneumatic Controller. Specific gravity rocker
arm and proportional bands are set direct for gravity
ranges between 0.5 and 1.5. For gravities above
1.5 or below 0.5, special elements can be used or
necessary compensation made by proportional
band setting.
1600 Electronic Controller. FM and CSA approved
Class I, Div 1 Groups C&D. Gravity ranges same as
72-45. Two-wire loop powered. Available as transmitter
only or transmitter with proportional plus
integral control. Set point, proportional band, and
integral are entered via key pad.
