1.0 Installation

Caution: If equipment is used in a manner not specified by manu-facturer, protection provided by equipment may beimpaired.

1.1 Unpacking

Unpack the instrument carefully. Inspect all units for damage. Report any concealed damage to carrier within24 hours. Check the contents of the packing slip andpurchase order. Check and record the serial number forfuture reference when ordering parts.

Caution: Do not discard the shipping container until all parts arechecked.

1.2 Pre-installation Checklist

1. Manually move the float from 0% to 100% to 0% priorto start up/check out in order to reinitialize accessoryproducts, if so equipped. Accessories may inadvertentlychange state due to rough handling in shipment.

2. Remove float prior to pressure testing tank.

Caution: Float damage will occur if not removed from chamber priorto pressure testing the tank.

3. Verify the MLI’s center to center distance equals thevessel’s center to center.

1.3 Equipment and Tools

• Open-end wrenches or adjustable wrench to fit the processstuds and nuts. A torque wrench is highly desirable.

• Flat-blade screwdriver

• Digital multimeter or digital volt/ammeter if transmittersor switches are attached

• Level

• Gasket for mating flanges

• Teflon tape & “never seize” for threaded units

• Pipe wrench for threaded units

1.4 Side Mount Installation

Caution: This instrument is intended for use in InstallationCategory II, Pollution Degree 2 locations.

NOTE: Top of gauge nameplates are available as an option.

The MLI nameplate can be used as bottom reference ofthe external cage. Install the cage to the vessel with name-plate at bottom. Isolation valves are recommended forinstallation between vessel and external cage. Check toensure the external cage is vertical. All piping should bestraight and free of “low spots” or “pockets” so that thelower liquid connection will drain toward the externalcage. Adjust piping as required.

It is recommended a drain valve be installed in the bottomflange to allow cleaning and checking level. Close theisolation valves until start up.

Initial installation of the Magnetic Level Indicator is sim-ple. Unless otherwise specified, MLIs will be shipped fromthe factory fully assembled. All flanges will be torqued toANSI specifications. Make sure all process connectionsattached to the vessel which the gauge will be mounted toare vertically level, and flanges, if any are level.

Carefully unpack the MLI and stand it up vertically.

NOTE: Longer units require support of the entire length of the cham-ber while being lifted in place vertically. This will prevent bow-ing of the chamber, that could result in glass breakage. Oncethe gauge is mounted to the vessel and the liquid level risesinside the vessel, the gauge will become operational

Isolation valves are recommended, but not required. Ifisolation valves are used, care must be used when openingthe valves to prevent a surge of fluid or gases through thechamber. A surge can cause the float to be propelled to thefar end of the chamber, and float damage could result.

Caution: If for any reason the MLI is pressurized higher than themaximum pressure indicated on the name tag, the floatinside the chamber is subject to collapsing and causingfloat failure.

NOTE: Float is shipped in chamber.

1.5 Top Mount Installation


The top mount gauge can be installed as one completeunit or disassembled to allow access from inside the tank.

Correct vertical installation is required to assure properfloat movement.

To disassemble you need only to unscrew the threaded capat the bottom mounting flange or connection.

Caution: Proper precautions should be taken to prevent thebending of the guide rod.

1.6 Top/Bottom Connection Installation


Carefully unpack the MLI and stand the unit up vertically.Note the float stop disc at the bottom flange. Note thefloat stop bar (welded in place) at the top of the gauge.This always indicates the top of gauge.

The float is shipped in the chamber.

Caution: Overall length should be ± 1⁄16". Smooth float travel must beassured by no bending of the chamber pipe.

1.7 Start-up

Increase system pressure slowly while commissioning theinstrument. Thoroughly check for leaks, and verify thatthe local indicator device accurately tracks the liquid level.Verify external accessory devices (switches, transmitter, etc.)are functional and properly calibrated.

Caution: Do not open the bottom isolation valve quickly. Allow thelevel to rise until the MLI displays the correct level in thevessel.

Caution: If equipment is used in a manner not specified by themanufacturer, protection provided by the equipment maybe impaired.

Remove the cover of the enclosure. Position the OES-100cam-operated snap switch on the MLI body so that thecenterline of the switch enclosure is at the desired switchpoint level. Ensure that the switch is oriented so that thearrow on the switch mechanism is pointing toward the topof the MLI. Install the clamps around the MLI and overthe mounting brackets on the top and bottom of theswitch housing. Tighten the clamps so that the switch issecured to the MLI. Replace housing cover. If required,place the insulation between the MLI body and the switchbefore tightening the clamps.

1.9.1.2 Mounting to an Aurora MLI

The Aurora may be ordered with one or more OES-100clamp-on switches. During assembly Orion can ensureproper function of the switches. Special care must be takenwhen adding OES-100 switches to an Aurora after initialpurchase. For proper function, the switch must be locatedas close to the internal float magnet as possible. This isachieved by marking the location of the indicator on theAurora body. The indicator must be rotated on the cham-ber so that the switch can be positioned closest to thefloat. Loosen the indicator clamps, rotate the indicator90 degrees around the chamber and retighten the clamps.Mount the OES-100 switch where the indicator wasoriginally located. Move the float, or move level, to verifyproper operation of the switch.

1.10 Analog Transmitter Installation

1.10.1 OCT-400 Reed Transmitter

The OCT-400 analog transmitter mounts directly to theside of the Atlas or Gemini chamber, providing a continu-ous 4–20 mA output signal proportional to liquid level.Using simple and reliable reed switches surface mounted toa printed circuit board, the unit provides level accuracy of±0.50" (13 mm).

The OCT-400 reed transmitter is shipped attached to theMLI gauge and is precalibrated to the customer specifiedspan. See Figure 10. Refer to Figure 11 for wire termina-tions for the OCT-400.

Installation is simplified by utilizing gear clamps that canbe repositioned with a screw driver.

Caution: If the MLI is insulated, the analog transmitter probe must belocated outside of the insulation blanket.

NOTE: For supply connections, use wire with a minimum rating of+167° F (+75° C) as required by process conditions. Use aminimum of 14 AWG wire for power and ground field wires.

NOTE: Housing must be grounded via protective ground screw in thebase of the housing.

NOTE: It is the responsibility of the customer to comply with applicableinstallation codes and practices. Class I, Division 1 locationsmay contain explosive gas mixtures. Appropriate precautionsmust be taken. Installation should be performed by qualifiedpersonnel.

Caution: In hazardous areas, do not power the unit until the conduitis sealed and the enclosure cover is screwed down securely.

1.11 Internal Electronic Transmitter Installation

The Gemini Model enables the customer to install severaldifferent types of either continuous measuring instruments(transmitters) or point level control devices (switches). Theelectronic instrument is installed in the 2" or 3" secondarychamber of the Gemini MLI. The factory should be con-sulted for these applications to review operating parametersand to ensure that the desired instrument is properlyapplied.

As the electronic instrument is supplied separately fromthe Gemini MLI, the instruction manual for the electronicunit should be carefully reviewed prior to installation inthe chamber. The instruction manual will be shipped withthe instrument.

1.12 Internal Eclipse Transmitter Installation

The Eclipse Guided Wave Radar Transmitter can bemounted in either the Gemini or the Aurora MLIs. TheAurora is designed to support operation of the Eclipse inthe same chamber as the float. Due to this, the coaxialtype probe must be used. With the dual chamber Geminidesign, either the twin rod, coaxial, or single rod typesmay be used. Caution should be exercised in probe selec-tion to take into account, media dielectric, viscosity, tem-perature, pressure, transition zone distances and overfillrequirements. Each Eclipse will be supplied complete withan instruction manual. A review of the manual is recom-mended prior to installation of the Eclipse transmitter inthe Gemini or Aurora MLI.

NOTE: Flag or shuttle indicator can be designed for mounting at anyangle. Do not rotate indicator after gauge is manufactured,due to inability to rotate baffle plate once welding has beencompleted.

2.0 Reference Information

2.1 Description

Magnetic Level Indicators (MLIs) are suitable for installa-tion on process applications that will not restrict float travelin the piping column. It is a magnetic coupled, local levelindicator which is isolated from the process in a sealednon-magnetic external cage. Bi-color flags provide visualindication of level up to 100 feet. Field-adjustable levelswitches and transmitters are available as options.

The Atlas is a magnetically coupled local level indicatorisolated from the process via a sealed non-magnetic exter-nal chamber. A fluorescent orange shuttle or series of bi-colored flags provide visual indication of liquid level fromdistances of up to 100 feet. Available switches for pointalarms include electronic DPDT, reed and pneumatictechnologies. Transmitter technologies for continuous4–20 mA outputs include reed and guided wave radar.

Atlas is suitable for installation on process applicationsincluding corrosive services that do not impede the move-ment of the float in the piping column.

Aurora and Gemini incorporate a combination of theAtlas magnetic level gauge and Magnetrol’s EclipseGuided Wave Radar. This represents the industries firsttotally redundant mag gauge/transmitter combination.


Local indication, 4–20 mA output, HART and Fieldbusprotocols are available. Float damage will not result in lossof the 4–20 mA signal

Aurora: The Eclipse Guided Wave Radar probe is mount-ed directly inside of the Gemini chamber. a minimum3" chamber is utilized to accommodate the Eclipse probeand allow unobstructed float travel. Patent pending.

Gemini: The dual chamber approach also accomplishestotal redundancy but increases the ease of gauge or trans-mitter isolation. The Atlas gauge provides local indicationwhile the Eclipse is mounted directly inside a connectedsecond chamber. The units perform independently ofeach other.

2.2 Theory of Operation

2.2.1 Side Mount

A float equipped with a strong magnet assembly inside andweighted to the specific gravity of the fluid to be measured,moves up and down in a non-magnetic chamber, as thefluid inside rises and falls with the level of the liquid inthe vessel.

Attached to the external wall of the non-magnetic chamberis a non-porous glass tube. Inside this hermetically sealedglass tube is a highly visible fluorescent orange indicator orflags with a strong magnetic assembly inside. See Figures12 and 13.

The indicator is always coupled to the float magnetically,to indicate the exact measurement of the fluid.

2.2.2 Top Mount

A top mounted float assembly consisting of a magnetassembly at the top, a guide rod in the middle, and a floatat the bottom. The float at the bottom is submerged in theliquid inside the vessel. The entire guide rod assembly isweighted to the specific gravity of the fluid to be measured.

Attached to the external wall of the non-magnetic chamberis a non-porous glass tube. Inside this hermetically sealedglass tube is a highly visible fluorescent orange indicator orflags with a strong magnetic assembly inside. See Figures12 and 13.

The indicator or flags are always coupled to the magneticassembly, to indicate the exact measurement of the fluid.

2.3 Troubleshooting

2.3.1 Side Mount

Problem Solution

Flags do not rotate with level change. Test flags with a magnet from bottom to top (magnet notincluded). If flags test okay, check for float obstruction.(See Section 2.5, Maintenance on page 16)

Flags rotate at different height than actual level. Float selected for different specific gravity. Replace float witha float with correct specific gravity rating. Confirm correctnessof float orientation. Top is up.

Float inside the level gauge is moving Make sure the MLI is level vertically.slow or not at all.

The process fluid being measured may be too viscous andheat tracing may be required to make the material more fluid.Heat tracing can be purchased from the factory.

The specific gravity of the process fluid and the float weightmay need to be reverified.

The liquid being measured may contain magnetic particlescollecting on the magnetic section of the float causing drag.If this happens, magnetic trap assemblies can be purchasedfrom the factory.

Visual inspection of the float may be required to see if the floathas collapsed.

Switch does not actuate with level change. Check micro switch for continuity. Replace if damaged. Ifokay, remove switch from piping column and test switch mag-net assembly with re-alignment magnet, by moving magnetover the housing face. If the switch magnet assembly fails torespond, replace the switch. If the switch tests okay, checkfloat travel.

Problem Solution

Shuttle indicator has uncoupled and In some “flashing” applications, the float may rise or fall quickly.fallen to the bottom of the glass tube. Consult factory for suggestions to help avoid this.

To re-couple the indicator to the float, simply use a small mag-net and run it along the length of the chamber to locate thefloat. Mark the location of the float on the outside chamber.Use the small magnet to couple with the indicator and pull theindicator up to meet and couple with the float.

Make sure all stainless steel gear clamps are tight. The scalechannel must be tight against the chamber.

NOTE: Ensure unit installation is level.

2.3.2 Top Mount

Problem Solution

The float assembly or visual indicator is Make sure the vessel opening or flange connection that the to moving slowly or not at all. mount flange connects to is level.

The top mount guide rod assembly may be bent. Visual inspec-tion is required.

The process fluid in the vessel may be too viscous, Heating thevessel to make the process fluid more liquid may be required.

The specific gravity of the process fluid and the float may needto be reverified.

Visual inspection of the float inside the process fluid may berequired to see if the float has collapsed.

2.5 Maintenance

Periodic inspections are a necessary means to keep yourlevel control in good working order. This control is a safetydevice to protect the valuable equipment it serves.

If the process liquid is clean (no solids or deposits), theMLI should require minimum maintenance. If the processliquid is dirty (solids and deposits), it is recommended theexternal cage be isolated from the process and flushed peri-odically. For complete cleaning, after draining the unit,remove the bottom flange and float, inspect cage and floatfor buildup and clean if required.

Magnetic traps are available to prevent magnetic particu-late travel from the vessel to the chamber.
