The FT430 flow computer is a microcontroller-based indicator/transmitter that interfaces with pulse output flow sensors to compute and display flow rate, flow total, and also generate output signals representing flow. It has one scaled pulse output and one pulse pass through. Galvanic isolation is provided for pulse outputs.
Pulse outputs can be used to signal external devices, e.g. certain metering pumps and water treatment controls. Alternatively, one or more pulse outputs can be configured as alarm outputs. These flow computers can be password protected to prevent resetting the total or changing configuration settings.
The FT430 offers the most flexibility of the FT400 series.
While the FT440 is loop-powered and the FT450 is battery-powered, the FT430 is DC-powered. It can be powered by an external power adapter (such as the Seametrics PC3) or it can be ordered with the "-140" option (for wall-mount units only), in which case it can be powered by 120/240 VAC.
Other options available are:
Tamper-Evident Kit ("-32"): A wire with a seal runs through the screws, so that the unit can't be opened without breaking the seal.
Non-Resettable Total ("-64"): Normally, the "Total" display on the unit can be reset to zero with a simple key-press. With this option, that can't be done.
Hinged Display Cover ("-126"): A protective clear cover over the display/keypad. Recommended for all outdoor applications. Incompatible with the "-27" or "-65" power supply options, as these units have a different housing.
