SpecificationsGeneral Information

The SeaMetrics FT410 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. Wall and meter-mounted enclo-

sures are NEMA 4X; Panel-mounted enclosures are

NEMA 12.

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 (an

optional dry contact pulse output is available) which is

compatible with electronic metering pumps, PLC's, com-

puter input cards, and SeaMetrics controls. An optional

4-20 mA output feature is front-panel programmable in

standard flow rate units.

FT410 Flow Computer Instructions Specifications The SeaMetrics FT410 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 recording, 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.

Installation FT410W: Wall Mounting. Four 3/16" screw holes are located at the bottom of the front cover screw holes. Mark the locations through the holes, then drill. Slip screws down the holes and tighten. FT410P: This unit is ordinarily supplied without pre-wiring. To reach the terminals, remove the four screws which hold the back cover of the housing in place. Follow the connections diagram Analog Output Board.

Set 4-20 mA Span. If the optional 4-20 mA board is installed, the prompt SET 20 mA will appear. Set this value to the flow rate, in units per minute, at which the full 20 mA output is desired. Zero flow will automatically be scaled to 4 mA. The only field-repairable component on the FT410 is the fuse. The fuseholder is found on the back of the circuit board stack. Replace with a Littlefuse 3AG 1/2-Amp or equivalent automotive-type fuse.
