Measuring
System
TheSparlingTigermagEPTM ModelFM-626,FM627,FM-656 andFM-657flowmetersare
obstructionless devices for monitoring the volumetric flow of conductive liquids infull closed
pipes.
Theflowmeterconsistsofasensor(waferorflanged)withanonmagnetic liner,sensing
electrodesand ameasuringtransmitter.
Operation is based on Faraday s Law of
Mag- netic Induction. An electrically
conductive liquid flowing through a magnetic
field induces avolt-
Operating
Principle age which is perpendicular to this field and to
the direction of the flow. This voltage is
proportional to theaverage flow velocity. See
Figure 1.1.
The mathematical formula describing
Faraday s lawreads:
E = B x L x V
E=Induced voltage
B=Magnetic field intensity (flux
density) L =Distance between the
electrodes
(pipe diameter)
V = Average flow velocity of
liquid

Flow
Measurement
Measuring Principle
Figure 1.1
In a magnetic flowmeter the liquid acts as a moving conductor as it flows through the pipe. The
induced voltage (E) in the liquid is measured by two sensing electrodes mounted opposite
each other in the meter sensing head.
The length of the conductor is equal to the distance between sensing electrodes and also
the internal diameter (D) of the pipe. The flux density is proportional to the coil current (I),
times aconstant (k). The above formula can be restated asfollows:
E= I xk x D xV
flow 0
V =
cross sectional area
=
A
0 x I x 4 x k
E =
D
2
Note that if I is held constant, E is proportional to0or theinduced voltageis directly
proportional to the average flow rate (V).

Interference
1.4.1 ElectrochemicalInterference
The signal voltage is measured by two electrodes. Galvanic elements form on the surface
areas between the ion-conducting liquid and the metal electrodes. The polarization voltages
which result are dependent on temperature, pressure, and the chemical composition of the
electrodes and liquid. These are direct voltages which cannot be predicted and which can be
different at each electrode. The signal voltage must be separated from the interference
direct voltage. Proper grounding eliminates these unpredictable voltages from interfering
withthe signal voltage.
1.4.2 InductionInterference(Quadrature)
Electrode cables connect the electrodes with the meter electronics. Because these cables
must run within the magnetic field, a voltage is induced which is proportional to the rate of
change of the magnetic field strength. The meter design minimizes the length of conductor
within the magnetic field in order to keep thevalue of this interference as low as possible.
1.4.3 Other InterferenceVoltages
Pipes and the liquids within them are often used as a conductor for electrical grounding. This
creates a voltage potential between electrodes which can be high relative to the signal
voltage. Proper grounding of the flowmeter to the liquid is necessary to achieve correct meter
operation. Grounding rings should be installed if theflowing medium has a voltage potential,
if piping is nonconductive (plastic or lined) or if conductivity is below 20 micromhos/cm. See
Section 3.8 -Grounding.

System
Operation
The Sparling TigermagEP™ uses the autozeroing, bipolar, pulsed-DC measuring
technique. The circuitry (Fig. 1.2) energizes the coil with 300 mA typical current at a
frequency ofupto 100 Hz. The signal generated at the electrodes is measured near the end of
each measuring cycle to eliminate the capacitive effects of coatings. The Hi-Z (1012 Ω) input
impedance eliminates the resistive effects of electrode coatings. The field current alternates
to a positive and negative state and the two measured signals are averaged to eliminate the
effect ofazero offset-this is the auto-zeroing feature.

Construction
1.6.1 Sensor
The FM626 is a wafer style meter. It is available with either a ceramic or optional Tefzel®
liner. The Tefzel® lineris rotamolded onto astainless steelsensor tube. Both liners arepress-
fit into acarbon steel housing. The FM627 is a wafer style meter. The flow sensor housing is
made of steel with a polyurethane liner. Sensor coils are completely encapsulated in
polyurethane. The FM656 flow sensor is a welded fabrication of 304 stainless steel, fitted
with two carbon steel flanges. The flow sensor contains a nonconductive liner of ceramic,
polyurethane, Tefzel®, hard rubber, soft rubber, or neoprene. The FM657 flow sensor
housing is made of steel with a polyurethane liner. Sensor coils are completely encapsulated
in polyurethane. All TigermagEP™ meters are rugged, waterproof assemblies capable of
handling awide range ofhighly corrosive and abrasive liquids.
Fused platinum electrodes, standard on ceramic meters from 0.1" to 2", require no O-
rings, eliminating the possibility of leaking. Platinum is suitable for nearly all conductive
liquids. The electrodes in all other liners are self-sealing.
All internal cavities of the FM-626 sensor housing are filled with a high temperature silicone
potting compound to prevent the possibility of moisture damage and to avoid the possibility
of collection of explosive gases.

PAGE25).
1.6.2 Integral Transmitter
The transmitter is mounted on the meter body and housed in a NEMA-4Xand NEMA-7 enclosure
thatis approvedbyCSAandFactoryMutual.Thepowerandsignalelectricalconnectionsaremadein
aseparate section of thehousing which is isolated from theelectronics.
1.6.3 Remote Transmitter
Thetransmitter ishoused in a NEMA-4X enclosure somedistance away from the meter
body. Remote mounting is recommended where pipe vibration is excessive or when
floodingis
possible.
Remote mounting tor the FM626 and FM656 is REQUIREDwhen high process
tempera- tures exist at high ambient temperatures (above 212° F/100° C). The FM627
andFM657should notbeinstalled where process temperatures will exceed 180° F.
The optional remote mounting kit includes interconnecting cable between the sensor
and transmitter enclosure. The standard interconnecting cable length is 15 feet.
Shorter or longer cables should be specified when ordered from the factory. The cable
maybeshortenedinthe field.

Returnof
Equipment
When the equipment is received, the outside of the package should be inspected for damage. If any
damage or shortage is found, notation to that effect should be made on the carrier s delivery receipt.
Visually inspect the sensor and transmitter for damage from rough handling or faulty packaging. If
concealed damage is discovered, notify the delivering carrier at once and request an inspection.
Confirm telephone conversations in writing. If inspection is not made, prepare an affidavit stating that
you notified the transportation company and that they failed to inspect. Save containers and
packaging material.
It is essential that the carrier be notified within 15 days from the date of delivery in order to be in a
position to present your claim. Make your claim promptly.
Unpacking and handling of TigermagEP™ Magnetic Flowmeters should be consistent with the
procedures used to handle field instruments.
This equipment should be stored in a clean, dry environment. Do not store outside in an unprotected
area. Observe the storage temperature requirements. Unpowered storage should not exceed two
years.
Obtain an RGA (Returned Goods Authorization) number from the factory prior to returning
any materials. The RGA number should be marked on the outside of the package. Failure to
obtain authorization will unnecessarily delay any work to be performed at the factory.
CAUTION
Page 10 TigermagEP™
When the meter is returned to our factory,
a statement MUST be attached indicating
the liquid that was flowing through the
meter, the concentration of the liquid, and
that the meter has been decontaminated
and flushed clean.

Site Selection
Installation
The TigermagEP
TM
can be used to accurately measure the volumetric flow rate of liquids having a
conductivity of at least 5micromhos/cm.
The presence of entrained air or gases in the process liquid will not prevent meter operation, but will
producea positive (+) error equal to the%by volume gas entrainment.
▼FULLSCALE FLOW RATESSHOULD BE
SELECTED ABOVE 3FEET PER SECOND (1 METER
PER SECOND) FOR BEST ACCURACY.
Select a pipe location which will always be full of liquid. The equipment should be located where the
flowmeter will be accessible for adjustment. Provide a minimum of 18"clearance to the electronics
enclosure.
Themeter may be located in anyposition from vertical to horizontal. Flow may be in either direction
through the meter. Vertical installation with the liquid flowing upwards, minimizes the possibility of
slurryseparation and assures a full pipecondition.
Full Pipe
Required
Figure 3.1
Horizontal installationrequires thatthesensing electrodes be positioned inthehorizontalplane. See
Figure 3.7.
Provide at least three pipe diameters of straight piping approach between an upstream elbow and
the midpoint of the meter. In small meters this can be achieved within the meter itself. More straight
approach should be provided after valves or multiple elbows. Provide at least 10 diameters after
expanders or laterals which are of smaller diameter than the line size.

Rotating the
T r ansmitter
Display
The Sparling TigermagEP's modular display is designed to allow you to rotate the display in four
different orientations. The display assembly can be rotated, at 90° intervals, by removing the two
screws circled in Figure 3.2 below, for ease of reading thedisplay.
The display features long lasting LCD numerals. The display may darken if ambient temperatures
exceed its temperature rating of -4° to+158° F.Darkening usually occurs when the electronics are
installed in direct sunlight. Toavoid this problem install a sun shield when the flowmeter is in direct
sunlight.
The display assembly can be replaced in the field without replacing the entire electronics, by following
the
same procedures as utilized for rotating thedisplay.

Removable
Electrodes
(optional)
The line must be depressurized and drained in order to check and replace the removable
electrodes.
3.4.1 How the Design
W orks
This design utilizes electrodes which are installed through accessible ports provided on the sensor
body. Electrodes are sealed using two o-rings. One o-ring actsas a primary seal while the other is
a backup seal. This redundant sealing approach provides positive sealing.
To withdraw the electrodes, process line has to be depressurized and drained. The outercover
must be removed by unscrewing cap bolts using an 11/32 nut driver to allow access to the elec-
trode
cavity. Remove cables from electrodes by removing nuts and lock washers. Usinga 3/4"
socket, unscrew and remove the electrode assembly.
3.4.2 The Need for
Replacement
Sparling's flowmeter design utilizes High Impedance circuitry (Hi-Z) which isnot affected bycoating
buildup on the electrodes. Replacement of the electrode only becomes necessary when physical
damagedue to erosion or corrosion hasoccurred.

Hot-Tap Removable
Electrode
Figure 3.4
Sparling's optional hot-tap removable electrode design allows the inspection or replacement of
electrodes without stopping the flow or depressurizing the line. The electrode assembly is sealed
with multipleo-rings to
maintain isolation from the pressurized medium. During removal of the
electrode, a stainless steel ball valve is closedto keep the process fluid from leaking out while the
electrodes are inspected or cleaned. The electrode housing, wired as a backup electrode, func-
tions as a redundant electrodeassemblyproviding the flow signal to the electronics. In other
words, even when the electrode is withdrawn, the flowmeter keeps on providingimportantflow
information.
