Seametrics FT400 Series Rate & Totalizer Indicator

Description

The FT430/440/450 series consists of microcontroller-based flow computers designed to interface with pulse sensors to display flow data and signal external devices via pulse or analog outputs. The primary distinctions between the models are their power sources and specific applications: the FT430 provides the greatest flexibility with external DC or AC power options, the FT440 is a “loop-powered” device ideal for 4-20mA requirements, and the FT450 is powered by an internal battery. All models support versatile mounting configurations and include password protection to ensure the integrity of totalized data and settings.

*Internal power supply is available for the wall mount option only
