BE48-110-15 Pneumatic Modulevel

®
STEEL FABRICATED MODELS
Pneumatic Modulevel® controls are displacement actuated
level sensors. They provide output signals in direct proportion to changes in liquid level.
Simple, modular design and proven magnetic coupling
make Modulevel controls versatile, highly stable, vibration
resistant and adaptable to extremes of temperature and
pressure.

Standard models handle service temperatures from
-100°C to +370°C (-150°F to +700°F) and pressure to
294 bar (4265 PSIG).
Stable output signal is unaffected by surface turbulence.
Prevents control valve "hunting" and extends valve life.
Controller head may be removed and bench calibrated
without dismantling or even depressurizing the tank.
Accurate output signal provided over a wide specific
gravity range.
316 SS displacer and trim.
Easily field calibrated without moving tank liquid level,
for reduced installation time and cost.
Controller head rotates 360°, simplifies pneumatic piping hookup.
Pilot relay provides a 4 to 1 amplification of pilot pressure signal to speed valve response.
Built-in visual level indicator is independent of air supply.
Optional pneumatic to current interface transducer for
use in electronic control applications.
Optional proportional plus integral control.
Optional differential gap (on-off) control.
Optional Hi-Lo electronic alarm signal provides inexpensive
backup alarm.
APPLICATIONS
Pneumatic Modulevel® liquid level controls are widely used
in utility power generation, chemical and petroleum processing operations, such as:
• Steam generator feedwater heater regulation
• Fractionating column level transmitter
• Ethanolamine level transmitter
• Vent gas scrubber level control
• Drip pot condensate level control
• Flash tank level transmitter
Worldwide level and flow solutions
PRINCIPLE OF OPERATION
The key elements of the Modulevel pneumatic
control are the magnetic coupling, which allows
the controller to be mechanically isolated from the
sealed sensing unit; the range spring, which
dampens the action of the displacer, and the control head, which provides a modulated pneumatic
signal in direct proportion to the input from the
vertical motion of the displacer.
As the liquid level in the vessel increases or
decreases, the buoyant displacer rises or falls.
This motion, dampened by the action of the range
spring to prevent response to the rapid fluctuations of turbulence, is mechanically coupled to an
attractor ball, within an enclosed tube.
A magnet encircling the tube follows the attractor
ball, transferring the motion to a rotating cam,
which in turn operates a flapper against a nozzle
which increases or decreases the pressure within
the pneumatic relay. The output pressure signal
can be used in a variety of ways to operate a control valve or signal to alarms, indicators, process
controls or other devices. With optional integral
control, the pilot nozzle proportional signal is conditioned through an additional metering valve system, which will eliminate offset from the desired
control point.

PNEUMATIC CONTROLLER HEADS
Pneumatic Modulevel® controllers are available in a variety
of functions and styles to handle different application
requirements.
Single function heads
Single function heads fulfill one of the functions as
described below. Single function heads are available with
electric limit switches. Limit switches allow separate
high/low level alarms separate from the normal function of
the unit.
Transmitter/receiver heads
Transmitter/receiver heads combine the transmitter function with one of the controller functions as described
below.
Action
All controller heads can be set in direct or reverse action.
Direct action: level increases-output increases (eg. from
0,2 to 1 bar).
Riverse action: level increases-output decreases (eg. from
1 to 0,2 bar)
Side Mounted
(for narrow differential)
Model P68
Functions:
Proportional: the unit keeps the level within a calibrated
band (wide differential).
Proportional with reset: the unit keeps the level at a specific level (narrow differential).
Transmitter: continuous measurement, different field
instruments can be actuated/deactuated from the output
signal transmitter heads can be factory calibrated to detect
an INTERFACE under following conditions:
1. Minimum difference of 0.10 specific gravity between
both liquids.
2. The interface band does not exceeds the length of the
displacer.
3. The displacer is at all times immerged in liquid.
Consult factory when consulting units for interface applications. Both specific gravities must be supplied at the time
the order is placed.
Differential gap: the unit shows an output that remains
stable once the level exceeds the highest switching point
until the level drops under the lowest switch point. The unit
shows another output until the highest switch point is
exceeded again.
