GENERAL INFORMATION
The EX100/200-Series are adjustable depth insertion magmeters that fi 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 fl uids before the meter). Adapters mate
with standard 1-1/2” (11x/21x) or 2” (15x/25x) FNPT threaded
fi ttings such as saddles and weldolets which may be purchased
either locally or from Seametrics.
A rapidly reversing magnetic fi eld is produced in the lower hous-
ing. As the fl uid moves through this fi eld, a voltage is generated
that is measured and translated into a frequency signal proportional to fl ow rate. This square wave signal can be sent directly
to a PLC or other control or can be converted using any of the
Seametrics family of indicators and converters.

A modular system of electronics can be installed directly on the
fl 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
fi 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 fl ow output and immersibility are optional.
