GENERAL INFORMATION

EX800-Series insertion electromagnetic ﬂ owmeters 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 ﬂ ows, such as air-driven diaphragm pumps. With no moving parts, these meters can be used in “dirty water” 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 ﬂ uids 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 basic rate/total and pulse output, the FT430 is best. For analog output and display of rate and total, the FT440 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. Electronic 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 ﬁ xed depth insertion meters require special ﬁ ttings. Factory installation in the ﬁ tting 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 ﬂ ow output and immersibility are optional.
