Seametrics FT400 General Information

General Information
The SeaMetrics FT400 is a compact digital flow monitor
with user-programmed output features. Combined with
an IP Series insertion flow sensor or a WT turbine meter,
it is ideal for flow rate and total indication, chart record-
ing, and proportional chemical feed. It is available in wall
or panel-mount enclosures, or in a round cast-aluminum
housing mounted directly on a SeaMetrics meter. For
wall-mounting, the non-metallic enclosure is splashproof
and has a clear cover. The housing for panel mounting
is standard 1/4 DIN-sized, with gasketed front panel and
membrane switches.
An eight-digit totalizer is resettable, unless ordered with
non-reset option. Programming prompts simplify set up
by indicating the next step. Pulse output is a program-
mable 0.1 second open-collector transistor pulse, which
is compatible with electronic metering pumps, PLC's,
computer input cards, and SeaMetrics controls. An op-
tional 4-20 mA output feature is front-panel program-
mable in standard flow rate units.
