Magnetic Level Gages
Installation, Operation and Maintenance Instructions
Section 2.1.0. - Description
2.1.1. INTRODUCTION
Process Level Technology, Ltd magnetic level gages (MAG-GAGE®) are an indirect reading liquid level
indicator. The magnetic level gage series utilize non-magnetic 2.00-inch, schedule 40 chambers (standard)
manufactured to length specifications with process connections that match those of the vessel or tank. For some
high pressure, low gravity applications, a 3.00-inch schedule 40 chamber is available. The process connections
may be:
1. Side mounted, threaded, flanged or socket welded
2. Top and bottom flanged mounted
3. Tank top mounted
4. Combination
A variety of mounting styles is available to suit any vessel or piping requirements. Refer to the drawing depicting
magnetic level gage mounting configurations.
2.1.2. COMPONENTS
The gage chamber contains a magnetic float and is completely isolated from the indicator housing attached to the
outside of the gage chamber. External indicators consist of a single yellow or continuous flag/flipper models. The
magnetic float maintains a magnetic bond with the external level indicator. As the level of the process medium
fluctuates within the tank and gage chamber, the float reacts accordingly with the indicator recording the level of
the fluid within the chamber.
2.1.3. CHAMBER MATERIAL
Gages are manufactured to meet exact specifications of the process media such as operating pressure, temperature,
specific gravity, etc. Standard chamber materials are 316/304 stainless steel however any non-magnetic material
may be used. Other chamber materials that are available include CPVC, Kynar, Hastelloy, Alloy 20, Zirconium,
Monel, Etc.

Magnetic Level Gages
Installation, Operation and Maintenance Instructions
Section 2.1.0. – Description
2.1.4. INTERNAL FLOAT
A magnetized float is contained inside the float chamber and is designed to the requirements of the process
conditions. For this reason floats are not interchangeable unless the process conditions and gage chambers are
identical. The float moves freely inside the chamber reacting to fluctuating level changes within the adjoining
vessel.
2.1.5. FLOAT SUBMERGENCE
Under normal operating conditions, the float should be submerged about 80% or more in the process fluid. It is
important to note, however, that the position of the float in the media will vary with different process conditions.
Float magnets are located in the upper portion of the float.
2.1.6. GAGE RATINGS
Magnetic level gages can be designed for operating conditions from full vacuum service up to 5000 PSIG, 1100
degrees F, and a minimum gravities of 0.20. All magnetic gages with alloy chambers will have full ANSI ratings
based on flange classifications. Gages with CPVC, Kynar (PVDF) or Fiberglass shields will have 150 PSIG
ratings only.
2.1.7. HYDROSTATIC TESTING
Gage chambers are hydrostatically tested to 150% of indicated gage rating without floats installed. Floats are
tested individually. Gages can be field hydrostatically tested after installation at the operator's discretion.
CAUTION: Do not conduct hydrostatic testing of the magnetic gage chamber attached to a
process vessel with the float installed. If a gage is field tested with the float installed, the float
may crush and chamber may become damaged. This procedure will void the warranty.

Magnetic Level Gages
Installation, Operation and Maintenance Instructions
Section 2.2.0. - Level Indication
2.2.1. INTRODUCTION
There are two types of external level indication options offered by Process Level Technology, Ltd. for magnetic
level gages. The single indicator (ST)/(SST) is recommended for stagnant storage level applications with little or
no level fluctuations. The wide flag indicator (WF)(SWF) is recommended for turbulent or high vibration level
conditions.
2.2.2. SINGLE TRACKER INDICATION (ST or SST)
The single follower assembly used for indicating level consists of a rectangular yellow magnetic follower sealed
in a channel with a 316 stainless steel calibration scale marked in feet and inches, total inches or in centimeters.
The indicator is mounted parallel and immediately adjacent to the gage chamber to allow maximum magnetic
coupling between the float and the follower within the indicator channel. The indicator is sealed to prevent dirt
and moisture accumulation. A red bumper is positioned at the bottom of the channel to cushion the impact of the
follower against the cover. Although the yellow follower provides maximum visibility even at nighttime, retrofit
kits for illuminating gages are available.
2.2.3. SINGLE TRACKER INDICATION - REFERENCE GUIDE
A black reference guide in the center of the yellow follower allows the operator to match the graduated scale with
the level of the process fluid. A nameplate at the lower end of the scale provides zero level indication. If the
yellow follower is decoupled from the internal float's magnetic field, the follower will descend below the zero
point on the scale. Thus, when the vessel is empty, the level gage will read zero and the yellow follower will
remain visible. To prevent the float from losing magnetic coupling with the follower, a spring is mounted inside
the top and bottom of the gage chamber. This cushion the impact of the float against the chamber ends when the
vessel is completely full or empty. The float and the follower are magnetically coupled when the follower remains
visible. If the magnetic coupling is lost between the float and follower, use a hand magnet to attract the follower
until it is contained within the float's magnetic field. Refer to the Troubleshooting portion of the manual, Section,
2.7.2.

Section 2.2.0. - Level Indication (cont.)
2.2.4. WIDE FLAG/FLIPPER INDICTION (WF),(SWF)
Process Level Technology offers a continuous Wide Flag or Flipper style indicator as an option to the Single
Yellow Follower indicator. Flag indications are industrial grade level indicators which consist of a series of
ceramic flags, black on one side, yellow on the other. As the magnetic float reacts to level fluctuations, each flag
or flipper will rotate 180 degrees to reveal the opposite color.
Process Level Technology, Ltd. a flipper is housed in a rugged sealed housing with a recessed glass window and
rotates on a ceramic and stainless steel surface. This eliminates the flippers from sticking or hanging up. The
unique design prevents all flippers from rotating in excess of 180 degrees and each flag is magnetically locked to
the next. Wide Flag indicators are recommended where surging or turbulent level conditions exist. Each flag
indicator is 1.40 inches wide and is more visible than the standard single indicator. These are available with or
without scales up to 20 ft.
2.2.5. WIDE FLAG/FLIPPER INDICATION - REFERENCE GUIDE
Yellowrepresents liquid column, Black represents vapor space.
2.2.6. WIDE FLAG/FLIPPER INDICATION - RETROFIT
When flipper style indicators are purchased with a Process Level Technology, Ltd. magnetic level gage, no
installation is necessary. If the indicator is removed or a retrofit kit is purchased for a gage already in service,
however, the following steps should be noted:
1. The mounting clamps connecting the flipper assembly to the gage chamber are adjustable to most
manufacturers' standard, (i.e. 1.50 inch to 2.50-inch pipe). If the gage is in service and there is liquid in the
tank, only the flippers adjacent to the float will rotate to yellow when the indicator assembly is clamped on.
2. Run a magnet along the window of the indicator from zero to where yellow is showing as noted, or
3. Drain the gage to zero on the indicator, and then fill again. As the float rises, the level indicator will react
accordingly and will be reset properly.

Magnetic Level Gages
Installation, Operation and Maintenance Instructions
Section 2.3.0. - Installation
2.3.1. INSPECTION
All magnetic level indicators are securely packed in crates to provide maximum protection of the equipment
during shipment. It is important to unpack and inspect each gage upon receipt to insure the indicator and chamber
were not damaged in shipment. If you should find damaged parts, contact Process Level Technology, Ltd.
immediately. All Process Level Technology, Ltd. magnetic gages are fully insured against damage or loss unless
specified by the customer otherwise. Claims must be filed within 15 days from the date of receipt of shipment.
2.3.2. CHAMBER ORIENTATION
The magnetic float is packaged separately for shipment; the Float is strapped externally to the outside of
chamber which should be removed before installation. The float chamber should always be leveled vertically. If
it is not leveled correctly, the float may be magnetically uncoupled from the level indicator during operations.
2.3.3. CONNECTION VALVES
Valves should be installed between the process vessel and level gage to allow for isolation, draining, and cleaning
purposes. (See section 2.6.2. on Maintenance for more details on cleaning and maintenance procedures). Standard
block valves can be ordered with the gage or separately from Process Level Technology. Ball check valves are
not necessary for magnetic level gages. If certain valve specifications are required, please advise Process Level
Technology, Ltd. accordingly.
2.3.4. FLOAT ORIENTATION
The internal magnetic float has a preferred orientation vertically which is inscribed at the top of the float. Install
the float properly by taking note of the correct orientation through the chamber flange connection. If the float is
installed into the chamber inverted, it will not couple with the external indicator correctly, resulting in improper
level indication. Floats that are installed in gages with inverted chamber construction will contain a loop at the
top of the float for installation and removal purposes. Internal floats should be installed after any hydrostatic
field tests of the chamber and connecting vessel are complete.

Section 2.3.0. - Installation (cont.)
2.3.5. CHAMBER GASKETS
Standard magnetic level gages are supplied with 0.125-inch composition gaskets. If this type of gasket is not
compatible with the process media, appropriate gaskets should be used in replacement of those shipped with the
gage.
2.3.6. FLANGES AND CONNECTIONS
Process connections and vent/drain flanges are designed to meet each customer's specifications. All flange
boltholes straddle the centerline unless otherwise specified. Both male and female threaded connections and
socket weld connections are available. DO NOT WELD ON MAG-GAGE OR ON THE VESSEL WITH
INDICATOR AND FLOAT INSTALLED, THIS WILL DESTROY THE MAGETIC CIRCUIT.
2.3.7. INTERFACE APPLICATIONS
Magnetic level gages can be used to identify fluid interfaces only if the proper specific gravities have been
identified at the maximum operating conditions. The float can designed to float in one media while sinking in the
other. Immiscible oil over water levels is an example. Care should exercised, however, when using magnetic
level gages in interface applications because rag layers may exist which are difficult to identify.
Do not install a gage with two floats and two single indicators on one chamber for an interface. In this case the
two floats may collide causing incorrect readings. Chambers can be manufactured with multiple connections for
maximum process influx. The proper method is to install one gage per process phase, not a combination.

Magnetic Level Gages
Installation, Operation and Maintenance Instructions
Section 2.4.0. - Operation
2.4.1. INTRODUCTION
It is important that all instructions pertaining to entering magnetic level gages into service be read thoroughly first
before commencing with service operations. Failure to do so may void the warranty by subjecting the gage to a
potential safety hazard.
2.4.2. PROCEDURES
1. Check that the operating conditions, (temperature, pressure and specific gravity) are within that maximum
rating of the gage. Each gage has a permanent nameplate indicating process specifications, serial number,
tag number, etc. It is critically important to check that the specific gravity of the process media is specified
at the maximum operating conditions.
2. The gage chamber should be leveled vertically, empty, blocked in and isolated. Check to see that all drain
and vent plugs are in place. Close all vent and drain valves if plugs are not used.
3. For standard gages, install the float by removing the bottom drain flange located at the base of the gage.
The float is marked TOP to insure proper orientation. A spring is attached to the inside of the drain flange
to cushion the float when the vessel is empty. Reinstall the bottom drain blind flange with a new flange
gasket after the float is in place.
4. For inverted gages, remove the top vent blind flange from the gage chamber. Install the float by inserting
a string through the float loop and lower the float into position slowly. Remove the string from the float
and chamber after the float is resting on the bottom of the gage. An auxiliary magnet may be required to
recouple the indicator, (either single follower or flipper indicator), to the internal float.
5. Reinstall the blind flange with a new gasket. The gage chamber should be isolated with no opening to
atmosphere. Check to see that all drain and vent plugs are securely in place and that any vent and drain
connections are closed.

Installation, Operation and Maintenance Instructions
Section 2.4.0. - Operation
2.4.2. PROCEDURES (cont.)
6. When the gage is mounted and ready for placement into service, PARTIALLY OPEN THE TOP
PROCESS CONNECTION VALVE FIRST and very slowly to allow initial pressure and temperature
equalization between the vessel and the level gage. This allows the process conditions of the vessel to
equalize with the gage slowly and reach operating conditions at a slow, even, and reasonable rate.
7. CAUTION. DO NOT OPEN THE BOTTOM PROCESS CONNECTION VALVE FIRST. IF THE
BOTTOM VALVE IS OPENED FIRST WITH THE TOP VALVE CLOSED AND THE VESSEL IS
UNDER PRESSURE, THE INTERNAL FLOAT WILL RISE INSTANTLY AND LODGE ITSELF
INTO THE TOP OF THE CHAMBER CAUSING SEVERE DAMAGE TO THE FLOAT AND
CHAMBER.
8. After the float chamber has reached process conditions, continue to open the TOP process connection
valve slowly, allowing any liquid or condensate to enter the gage slowly. This procedure is critically
important for high pressure and temperature applications. The float and indicator may react or rise to
condensate accumulation migrating through the top valve with the bottom valve closed.
9. When the gage chamber has attained normal operating conditions, open the BOTTOM process valve
connection slowly. This will allow proper fluid entry into the gage chamber under normal operating
conditions. The level indicator should rise vertically, thus rendering a fluid level. Flag or flipper indication
will result in black to yellow rotation of the flippers as the fluid rises. At this point, installation should be
complete. Allow at least 30 minutes for both top and bottom valve procedures.
10. Please note, under elevated operating conditions, the indicator may record a significant level from
condensate influx through the top valve before the bottom valve is opened. If this is the condition, it is
possible the indicator (and float) may readjust and fall slightly from the effects of final process
equalization after the bottom valve is completely opened.
11. Extended Storage: All MAG-GAGE® magnetic level gages and gage accessories not put in service shall
be stored inside in the original creates

Section 2.5.0. - Removal from Service
2.5.1. INTRODUCTION
To remove the gage from service, the next steps should be followed to prevent danger to personnel and damage
to the gage when the vessel is pressurized.
2.5.2. PROCEDURES
1. Close the bottom process connection valve first to prevent further process influx to the gage.
2. Completely close the top process connection valve to isolate the gage from the process conditions.
3. Attach proper vapor collection equipment to the gage vent connection if required.
4. Open the vent valve slowly to relieve gage pressure and allow ambient air influx.
5. Attach the proper liquid collection equipment to the drain connection is required.
6. Open the drain valve slowly to remove remaining gage liquid.
7. CAUTION: Never use the vent or drain on a gage as a pressure relief mechanism for the process system.
Doing so may permanently damage parts of the gage as well as inducing a safety hazard.
8. DO NOT remove float from chamber before ambient temperature is obtained. Once ambient
temperature is obtained, wait an ADDITIONAL TWO HOURS before removing float from chamber
for safety purposes.

Installation, Operation and Maintenance Instructions
Section 2.6.0. - Maintenance
2.6.1. INTRODUCTION
Process Level Technology, Ltd. magnetic level gages contain a standard 0.50 inch vent and drain plug in the top
and bottom of the gage chamber to allow cleaning and removal of the process fluid if required. Socket weld vent
and drain valve connections are available. Some gages are connected to a solvent or steam line that allows empty
gages without floats to be decontaminated or blown down periodically without removing the gage from the vessel
location. Process Level Technology, Ltd. magnetic gages should be maintained and inspected on at least an annual
basis, or more frequently depending on the process system.
2.6.2. PROCEDURES
1. Block in the gage chamber with the process connection valves or wait until the vessel is empty and out of
service.
2. Close the bottom valve first and the top valve second.
3. Open the vent valve slowly or remove vent plug carefully to depressurize the gage especially if the gage has
been under pressure.
4. Open the drain valve slowly or remove the drain plug carefully to allow any remaining fluid to drain from the
chamber.
5. When all of the gage fluid has been drained, carefully remove the drain flange and float from the gage
chamber. Be sure to examine the float for excessive wear and clean as required.
6. Clean the inside wall of the chamber with a "bottle brush" or similar scrubbing tool. Some processes may
dictate the use of a suitable solvent for cleaning.
7. After cleaning of the chamber, replace the float and drain flange. A new flange gasket should be installed.
Use gaskets compatible with the process media if replaced.

Installation, Operation and Maintenance Instructions
Section 2.7.0. - Troubleshooting
2.7.1. INTRODUCTION
Process Level Technology, Ltd. magnetic level gages are simple to install and operate. The following
troubleshooting tips may be of assistance during installation and startup. Complete reading of this is required.
2.7.2. FLOAT & INDICATOR DETACHMENT
1. If detachment is a frequent problem, it could be caused by several factors, most of them resulting from
improper installation of the gage, particularly the float.
2. Check to ensure that the scale and channel assembly is fastened tight against the gage chamber so that
magnetic coupling is maintained from top to bottom of the indicator.
3. Check to ensure the internal magnetic float within the chamber is right side up. If the float was installed
inverted, the single yellow indicator will magnetically couple, but the actual process level will be higher that
what the indicator records. All floats are clearly marked TOP. Floats designed for inverted gages will have a
loop welded at the top of the float for installation and removal purposes.
4. If the float springs mounted in the top and bottom of the gage chamber have been removed, the float could
rise past the top of the indicator and lose magnetic coupling with the indicator.
5. If the process connection dimension has been miscalculated and the gage length is too long, do not attempt
installation because it will warp the chamber. A warped chamber will prohibit the float to move freely. This
can cause float and indicator detachment.
2.7.3. DIFFERENTIAL LEVEL
This can occur during startup and is easily corrected. Under normal operating conditions, most floats are about
80% submerged in the process media. It is important to note that the position of the float in the fluid will vary
with different process conditions. To attain a true level elevation, adjust the scale vertically to get an exact reading.

Section 2.7.0. - Troubleshooting (cont.)
2.7.4. DEFECTIVE INDICATOR
If the glass indicator cover is cracked or broken, a replacement cover can be shipped within 24 hours after receipt
of order. One advantage of the magnetic level gage is the indicator assembly can be serviced without removing
the gage chamber from service. To replace the indicator cover, remove the four screws from cover plate at the top
and bottom of the indicator channel. There are two red gaskets beneath each cover that require removal. Remove
the two red seal strips and slide the glass plate cover out of the channel. Clean any debris or fragments. Replace
the glass cover with the new glass plate by sliding into the channel again. Replace each red side and top gaskets
with the top and bottom covers. If the gage is inexcess of 6 feet in length, it may be easier to remove the indicator
from the channel.
2.7.5. SWITCH MALFUNCTIONING
All level switches may be wired to trip on rising or falling level. After the switch is connected to the desired alarm
function, it is necessary to set the switch. This is accomplished by passing the float either manually or by filling
the gage chamber until it passes the highest switch. This will trip the switch to the desired setting so it will alarm
properly with rising or falling level.
