Modulevel® Pneumatic and APM Liquid Level Control Modulevel pneumatic liquid level controls are displacement actuated level sensors that provide output signals in direct proportion to changes in liquid level. Simple modular design and the Magnetrol proven magnetic coupling make Modulevel controls versatile, highly stable, vibration resistant and adaptable to extremes in temperature and pressure. Features • Standard models handle service temperatures from -150° to +700° F (-101° to +371° C) and pressure to 4265 PSIG (318 Bar). • Stable output signal is unaffected by surface turbulence. Prevents control valve “hunting” and extends valve life. • Controller head may be removed without disturbing pressure boundary. Permits service or replacement without shutdown of process. • Simple calibration prior to installation, by substituting weights for displacer or by controller head calibration with displacer. • Accurate output signal provided over a wide specific gravity range. • Controller head rotates 360°, simplifies pneumatic piping hookup. • 316 SS displacer and trim. Inconel & 316SS range springs. • Easily calibrated without moving tank liquid level, for reduced installation time and cost. • Pilot relay provides a 4 to 1 amplification of pilot pressure signal to speed value response. • Built-in visual level indicator is independent of air supply. • Optional pneumatic-tocurrent interface transducer for use in electronic control applications. • Optional proportional plus integral control. • Optional differential gap (on-off) control. • Optional High-Low electronic alarm signal provides inexpensive backup alarm. • Fabricated construction. Applications Modulevel pneumatic liquid level controls are widely used in utility power generation, chemical and petroleum processing operations, such as: • Steam generator feedwater heater regulation • Vent gas scrubber level control • Fractionating column level transmitter • Drip pot condensate level control • Ethanolamine level transmitter • Flash tank level transmitter • Boiler level control SM Worldwide level and flow solutions Principle of operation Zero adjustment 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 controller 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. Pilot nozzle Flapper Cam Attraction ball Magnet Indicator Proportional band adjustment Proportional band spring 0 Enclosing tube 100 Range spring Actuating lever Set point adjustment Displacer Feedback bellows Reset bellows Check valve Reset valve 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. Relay Chamber Orifice OUTPUT 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.

Filter regulator and gauge Modulevel instruments require filtered air of the correct pressure for operation. Filter regulators may be either field or factory supplied. Filter regulators and gauges are ordered as separate items using the part numbers listed below: Filter Regulator Gauge 06-9501-002 06-9501-003 Adjustable hangar An adjustable stainless steel suspension cable is available for flanged top-mounting models. Standard length cable is 8 feet (2.4 meters). A cable is ordered as a separate item using the part number listed below: Adjustable hangar 32-3110-001 Special process connections Special process connections are available for retrofit applications. Gauge glass tappings Gauge glass tappings are available on all caged models. Specify the location and distance between the tappings when placing an order. P/I converters P/I converters are available on all Modulevel controls. These units can provide a 4-20 mA or 10-50 mA two-wire output signal from the Modulevel transmitter’s input air signal of either 3-15 PSIG or 6-30 PSIG. Mounting arrangements Modulevel® pneumatic instruments Flanged top P51, P61 and P62 displacer models Modulevel pneumatic instruments are available in a variety of functions and styles to handle different application requirements. For mounting on top of the tank, flanged top models are available. They are used extensively in interface control applications where non-standard size displacers become necessary. An adjustable stainless steel displacer suspension cable is also available. Top mounting models are directly interchangeable with the external cage models. Choose from carbon steel or stainless steel models. A heavy duty model, suitable for pressures up to 4265 PSIG at +100° F (318 bar at +38° C), is also available. P61 Flanged Top Model Top Mounted APM-131 When mounting inside the tank is possible, threaded top models are the answer. An adjustable stainless steel displacer suspension cable is provided as standard. Proportional integral Proportional instruments are used to maintain the level in a tank within a predetermined band. The output from the Modulevel head controls the opening and closing of a valve to control the increase or decrease of the liquid flow through the vessel. Proportional integral instruments (i.e., with reset) operate in the same manner as the proportional with one major difference. The offset between the desired level and the actual process level is eliminated; thus, maintaining the level at a specific point rather than within a band. Transmitter Transmitters are adjusted for full level range operation and signal the current liquid level. The signal can be fed to a variety of devices as the application requires. Top Mounted APM-131 External cage P53, P55, P63, P64, P65, P66, P71 and P72 displacer models External cage models can be easily isolated from the process for maintenance and inspection operations. The modern in-line design eliminates the need for specifying right hand and left hand. Any mounting position is possible by rotating the instrument head. A variety of models are available including sealed or flanged cage with either side/side or side/bottom connections. Choose carbon steel or stainless steel models. Heavy duty models, suitable for pressures up to 4265 PSIG at +100° F (318 bar at +38° C), are also available. Proportional P65 External Cage Model with Side/Side Connections External cage APM-W251, APM-W254 and APM-W291 Transmitter/Receiver controller There are two devices in this version. The first is a transmitter which senses the level directly at the vessel and provides a 100% of span signal to the receiver/controller. The receiver/controller operates in the same manner as a direct connected level device, such as a proportional controller, which allows varying the proportional band and level set point. This unit may be mounted either integrally next to the transmitter, or at a more convenient remote location . Differential gap A differential gap instrument provides only two distinct outputs; either, fully opened or fully closed. One distinct output value is obtained when the level exceeds the upper switching point. This output remains constant until the level decreases below the lower switching point. At this time the controller changes to another distinct output value. The new value remains constant until the level again rises above the upper switching point; causing the output value to return to the first output value. The distance between the two switching points is called the differential gap. Direct acting As the level increases, the pressure increases in direct acting pneumatic instruments. Electric limit switches Electric limit switches allow high and low alarms to be added to any of the pneumatic instruments described above. External cage models can be easily isolated from the process to simplify maintenance and inspection operations. Sight glass and Trycock tappings are provided. Reverse acting As the level increases, the pressure decreases in reverse acting pneumatic instruments. Interface detection Side mounted P68 float model Side mounted models are ideally suited for narrow level range applications. Carbon steel models are available with either a 3" NPT threaded body or a 4" flanged connection. This model is suitable for pressures up to 800 PSIG at +100° F (55 bar at +38° C). External Cage APMW251 Modulevel controllers can be factory calibrated to detect the interface between two liquids if: 1. There is a minimum difference in specific gravity of 0.10. 2. The interface line between the two liquids is kept within the length of the displacer. 3. The displacer is constantly submerged in liquid. Consult the factory when specifying units for interface applications. The specific gravity of both liquids must be supplied at the time the order is placed. 3 Model number construction Expedite ship plan (ESP) Many standard Modulevel pneumatic level controls are available for quick shipment, usually within one week after factory receipt of a purchase order, through the Expedite Ship Plan (ESP).
