GENERAL INFORMATION
EX100/200 SERIES INSTRUCTIONS
The EX100/200-Series are adjustable depth insertion
magmeters that t 3” to 48” pipe (up to 72” optional). The
complete lack of moving parts of the EX100/200-Series is
the source of its reliability. Brass and stainless steel models
withstand a variety of temperature, pressure, and chemical
conditions. The EX-Series has no rotor to stop turning in
dirty water and there are no bearings to wear out. Like all
magmeters, when used in chemical injection applications,
these meters should be installed upstream of the chemical
line (or far enough downstream to allow complete mixing
of uids before the meter). Adapters mate with standard
1-1/2” (11x/21x) or 2” (15x/25x) FNPT threaded ttings
such as saddles and weldolets which may be purchased
either locally or from Seametrics.
A rapidly reversing magnetic eld is produced in the lower
housing. As the uid moves through this eld, a voltage is
generated that is measured and translated into a frequency
signal proportional to ow rate. This square wave signal
can be sent directly to a PLC or other control or can be
Features
converted using any of the Seametrics family of indicators
and converters.
A modular system of electronics can be installed directly
on the ow sensor or mounted remotely. The FT430
(externally powered with pulse) and the FT440 (loop
powered), both provide digital rate and total displays, as
well as a programmable pulse; the FT440 also provides a
4-20 mA analog output. The AO55 is a blind analog (4-20
mA) transmitter. Programmable pulse for pump pacing is
available with the PD10.
The “hot-tap” models (EX15x/25x) can be installed or
serviced without shutting down the line by means of
a 2” full-port isolation valve that comes with a nipple
for installation on the pipe tting; a bronze ball valve is
standard, with a 316 stainless steel valve option if needed.
In most circumstances, no special tool is required.
Reverse ow output and immersibility are optional.

INSTALLATION
EX100/200 SERIES INSTRUCTIONS
Positioning the Meter
For best results, the EX100/200 sensor should be
installed with at least ten diameters of straight pipe
upstream and ve downstream. Certain extreme situations
such as partially-opened valves are particularly difcult and
may require more straight diameters upstream (see page 9
for straight pipe recommendations).

Immersion
The 100/200-Series sensors are not designed for underwater
operation. Even occasional immersion can cause damage.
If occasional immersion, such as when a vault oods, then
the -40 option, (immersion) is recommended.
Chemical Injection or Fertigation
When a magmeter is used in a chemical injection application
(including fertigation), the chemical line must be placed
downstream of the magmeter OR far enough upstream
for complete mixing to occur before the uid reaches
the meter. When unmixed chemical or fertilizer alternates
with water passing through the meter, the rapid changes
in conductivity may cause sudden spikes and drops in the
meter’s reading, resulting in inaccurate measurement. The
magmeter will restabilize, however, with a steady ow of
uid of uniform conductivity.
Caution: In chemical injection or
fertigation applications, install chemical
line downstream of magmeter, or far
enough upstream to allow complete
mixing of uids before the meter.
Horizontal (3 o’clock or 9 o’clock position) is the preferred
installation orientation, since it improves low-ow
performance and avoids problems with trapped air and
sediment. (See Orienting the Meter diagram below.) Bottom
(6 o’clock), top (12 o’clock), and vertical pipe installations
are all acceptable if required by the piping layout.

INSTALLATION
EX11x/21x Installation
Fitting Installation. EX11x/21x adapters mate with a 1-1/2” female
NPT pipe thread adapter tting. Any tting that provides the
matching NPT female thread may be used. Installation procedure
compensates for tting height differences. Cut a minimum 1-3/4”
hole in the pipe. If possible, measure the wall thickness and write
it down for use in depth setting. Then install the threaded tting
(saddle, weldolet, etc.) on the pipe.
EX100/200 SERIES INSTRUCTIONS
Compression nut
Meter Installation. Loosen the compression nut so that the adapter
slides freely. Pull the meter fully upward and nger-tighten the
compression nut. Using a thread sealant, install the adapter in the
pipe tting. Do not overtighten. Now loosen the compression nut,
lower the meter to the appropriate depth setting (see diagram and
instructions that follow). Be sure ow is in the direction of the arrow
on the housing. Fully tighten compression nut.
EX15x/25x Installation
‘Hot tap’ EX meters are designed so they can be installed and
serviced without depressurizing the pipe.
Fitting Installation. The EX15x/25x adapters mate with a 2” FNPT
threaded tting for compatibility with the 2” isolation valve. Any
tting that provides matching NPT female thread may be used. The
installation procedure compensates for differences in tting height.
If initial installation is performed on an unpressurized pipe, cut a
minimum 1-3/4” hole in the pipe. If possible, measure the wall
thickness and write it down for use in depth setting. Then install the
threaded tting (saddle, weldolet, etc.) on the pipe.

to use an installation tool, due to the small diameter tube the meter
can be installed by hand at all but the highest pressures.
Meter Installation. Remove the sensor unit from the valve assembly.
Using a thread sealant, install the valve assembly on the pipe tting.
If the initial installation is a pressure (“hot”) tap, remove the 1-1/2”
x 2” adapter bushing at the back of the valve. Thread the tapping
machine on, open the valve, and tap using a minimum of 1-3/4” or
maximum 1-7/8” cutter. After retracting the machine and closing
the valve, reinstall the ow sensor. When the sensor is secure, open
the valve and adjust depth setting (see diagram and instructions that

Depth Setting
It is important for accuracy that the sensor be inserted to
the correct depth into the pipe.
1. Please visit seametrics.com and select the K-factor
Calculator located at the bottom of the home page
to nd dimension D (insertion depth setting)*.
2. Measuring from the outside of the pipe to the joint
in the housing, as shown in the diagram, adjust
the sensor to Dimension D and hand-tighten
compression nut.
3. Align the conduit housing with the centerline of the
pipe, as shown. Be sure the arrow on the housing
points in the direction of ow.

Proper Depth Setting
Caution! Never attempt to remove a
ow sensor when there is pressure in the
pipe unless it is specically designed for
hot tap installation and removal. Loosen
the compression nut slowly to release any trapped
pressure. If uid sprays out when removing the
sensor, stop turning and depressurize the pipe. Failure
to do so could result in the sensor being thrown from
the pipe, resulting in damage or serious injury.

ELECTRICAL CONNECTIONS
EX100/200 SERIES INSTRUCTIONS
General Electrical Guidelines
• Whenever possible avoid running control cables in
the same conduit with or bundled with AC power.
• Using shielded cable, be sure to connect shield to
ground at power supply end of the cable. Do not
connect other end of shield.
• Avoid routing ow sensor cables in close proximity to
a variable frequency drive.
• Recommended power and output wiring is shielded
twisted pair 18-22 AWG control cable.
• Recommended voltage is 12-24 Vdc. Note that
unregulated power supplies can vary from nameplate
voltage by a considerable amount, especially with AC
line voltage uctuation. Therefore 24V power supplies
must be regulated.
See the Connections diagrams on the following pages for
the appropriate terminals.
Power
A 12 - 24 Vdc power supply capable of at least 250 mA
current output is needed.
Output
The standard output is pulses with ow in the forward
direction (Reverse ow output is optional [-15] ). Electrically
it is an open collector opto isolated switch. The output is
not internally powered.
Grounding Guidelines:
For best results, use a good quality earth ground, such as
metallic water piping or a driven ground, to ensure a good
connection to earth ground and good noise suppression.
If the ow sensor is installed in metallic piping, for optimum
connection clamp wire to the piping a short distance to one
side of the ow sensor using an electrical grounding clamp.
Connect the wire to the earth ground and to one of the
housing screws.
For Non-Metallic Pipe: Connect one to the housing
screws by wire to a good earth ground, such as metalic
water piping or a rod driven into the ground.
EX meters are usually unaffected by moderate levels of
electrical noise. In some applications performance may be
improved by taking the following steps:
• Use shielded twisted pair cable (Belden 8723 or
equivalent above ground or Alpha 35482 or equivalent
burial).
• Clamp a ferrite bead (Steward 28A2029-OAO or
equivalent) on meter signal/power wire within 3/4”
of the meter strain relief (tape or tie wrap in place if
necessary). See diagram below.
• IMPORTANT - Connect the cable shield ground
wire to ground, ONLY at power supply end of cable.
Note: This output is limited to 6 mA at 30 Vdc maximum.
Housing Screw
Earth Ground
Caution: The EX100/200-Series have
strong start and run currents. When using
solar panels and VRSLA batteries as a
power source, use caution to insure the EXseries sensor has the -50 Low-power Option and that
all Seametrics products on the power circuit receive
sufcient voltage and current under all conditions.
Failure to do so will lead to unreliable operation and
possible damage to the unit/s. Please reference
the technical bulletin, ‘Solar and Battery-Power
Guildlines’ available on our website: www.seametrics.

EX100/200 SERIES INSTRUCTIONS
Zero Adjustment
When the EX100/200-Series meter is powered up and
there is no ow, there should be no output pulses (or, if
connected to the FT430/440, ow rate should read “0”). If
there are pulses, it may be necessary to adjust the ow
meter under no-ow conditions after it has been installed.
This should only be done if the indicated ow is low,
near the lower cutoff.

Pins
Zero Adjustment
To perform the adjustment, after determining that there
is a full pipe with no ow, short between the two pins
marked “Zero Adjust”. A red LED light will come on for
approximately 50 seconds and then go out. The zero
adjustment is completed.
Minimum Flow
As with any other ow sensor, there is a rate below which
the EX100-Series sensor cannot read. Check the table
below for the minimum ow rate detectable by the sensor
for a given pipe size.
Presence of Flow Indication. To assist in troubleshooting,
the “Status LED” has two blinking modes in normal
operation. When there is no ow detectable by the meter
(below minimum threshold) the LED blinks every 8.0
seconds. When there is detectable ow, the same indicator
blinks every 3.0 seconds (Pulses are being output when
indicator is blinking every 3 seconds).
Filtering
The software of the EX100/200-Series lters out electrical
noise and averages sudden variations in the ow to smooth
the output. It takes a matter of seconds for the ow sensor
to get up to full output when it is powered up or when ow
begins.
Electrode Coating
Grease or other adhering, non-conductive materials can
stop ow detection if the electrodes become heavily
coated. To clean the electrodes, remove the sensor from
the pipe and gently scrub the electrodes (three silver
bumps) on the reading face of the ow sensor. A mild soap
(dishwashing liquid for example) can be used to aid the
cleaning process.
Calibration (“K-Factor”)
In order to properly process pulses from the ow sensor,
a number must be entered into the control to which the
sensor is connected. This number, called the K-factor,
is the number of pulses the sensor puts out per unit of
uid passing through the pipe. It is normally provided
for Seametrics sensors in pulses per gallon, and can be
ascertained by using the “K-Factor Calculator” on the
Seametrics website. These numbers are based on extensive
testing, which has shown close agreement among different
EX sensors in the same installation. Typically, most K-factor
error can be attributed to installation variables, such as
depth setting and tting conguration.
Using the K-Factor Calculator:
