SpecificationsGeneral 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.
