Seametrics EX800 Series Magmeters are insertion electromagnetic flowmeters designed for use with conductive liquids in 1 to 12 inch 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. 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 basic rate/total and pulse output, the FT430 is recommended. For analog output and display of rate and total, the FT440 can be used. Blind analog output is provided by the AO55. Electronic modules can be wall- or meter-mounted .

EX800-Series fixed depth insertion meters require special fittings. Factory installation in the fitting ensures correct depth placement in the pipe. The meter can be ordered in a full power model when 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. The stainless version with EPDM O-ring is certified to NSF/ANSI Standard 61 and NSF 372 .
