The Seametrics FT400 series flow computers are microcontroller-based indicator/transmitters that interface with pulse output flow sensors to compute and display flow rate, flow total, and also generate output signals representing flow. The FT430 and FT450 have one scaled pulse output and one pulse pass through. The FT440 has two scaled pulse outputs. Galvanic isolation is provided for most pulse outputs.

The Seametrics FT450 is battery powered. The FT430 may be pow¬ered by an external DC power source or an optional inter¬nal AC power supply. The FT440 is a "two-wire" or "loop powered" device, meaning that it is powered by the 4-20 mA loop circuit itself. An optional internal AC power sup¬ply is available for the FT440 with dual 24 and 12VDC outputs to power both the loop and sensors requiring more power than the loop can supply.

Pulse and 4-20mA analog outputs can be used to signal exter¬nal devices, e.g. certain metering pumps and water treatment controls. Alternatively, one or more pulse outputs can be con¬figured as alarm outputs. FT400 Series flow computers can be password protected to prevent resetting the total or changing configuration settings.

All Seametrics FT400 meters are available in wall and meter mount configu¬rations. The FT430/440 models can also be panel mounted. Some configurations of the FT400 series can be converted from wall to meter or meter to wall after installation if needed.

Order the FT440 only if a 4-20mA output signal is required. Order the FT450 if internal battery power is needed. Otherwise, the FT430 offers the most flexibility.
