Flow Controller FT-420 Series - Seametrics

The FT400-Series fow computers are microcontroller-based indicator/transmitters that display fow rate and total and provide output signals. The FT415 is battery-powered and provides a scalable pulse output. The FT420 is powered by external DC voltage and has both pulse and 4-20 mA analog outputs. When the FT420 is being used in the 4-20 mA mode, it is a “two-wire” or “loop-powered” device, meaning that the 4-20 mA output signal doubles as its power supply.

Seametrics Flow Controller FT420

Pulse and 4-20 mA analog outputs, both numerically scaled by the user

Rugged cast aluminum housing, covered with a heat-fused coating

Electronic components are potted for maximum moisture protection

Wall, flowmeter, and panel mounting

Non-volatile memory saves settings and total without a battery backup

The addition of a dual-relay output board (FT420 only) allows for certain applications requiring contact output isolation (e.g., certain metering pumps and water treatment controls). Dual solid state relays provide exactly the same pulse output as the standard unit, and each can signal one external device. A non-resettable total is also available. The FT420 can be ordered in a plastic enclosure with a 115 Vac power supply for use with mechanical meters, or with a built-in 115 Vac/12-24 Vdc dual power supply for magmeters.Both the FT415 and the FT420 can be factory-mounted on the meter (-M) or remotely wall mounted with the brackets provided (-W). The FT420 is also available as a panel mount (-P) with an open back for easy installation in the user’s own electrical enclosure. Most FT400’s can be converted from wall-to-meter or meter-to-wall mount confgurations after installation if needed.Housings for the -W and -M models are rugged cast aluminum, potted and gasketed for maximum environmental protection. A membrane keypad allows settings to bechanged without removing the cover. (Password protection, a standard feature, can be used to prevent settings from being changed.)
