TABLES AND DIAGRAMS
EX800-Series insertion electromagnetic flowmeters are
designed for use with conductive liquids in 1 to 12” pipe. A
choice of materials (stainless steel, brass, and PVC) allows
the meter to adapt to a range of temperature, pressure, and
corrosive environments.
The EX800 is highly suitable for difficult applications with
changing viscosities and pulsating flows, such as air-driven
diaphragm pumps. With no moving parts, these meters can
be used in “dirty” applications where debris would foul a
mechanical meter. 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 fluids before the meter).
Designed for modularity and versatility, the EX800-Series has
a current-sinking pulse output that can be combined with the
appropriate transmitter or indicator for the application. For analog output and display of rate and total, an FT420 can be
used. Blind analog output is provided by the AO55. The PD10
can be used to divide the pulse for pacing chemical metering
pumps and the DL76 (data logger) is also compatible. Modules
can be wall- or meter- mounted. If the EX800 meter is used with
a programmable controller, the output signal can be fed direct,
with no other conditioning required.
EX800-Series fixed depth insertion meters require special
fittings. Factory installation in the fitting ensures correct depth
placement in the pipe. The EX800-Series meter can be ordered
in a full power model when a source of electricity is available, or
in a low power model that can run on an external battery with
solar panel.
Reverse flow output and immersibility are optional.
