The FT500-Series is a batching flow processor with additional 
output controls. It is designed for use with Seametrics flow 
meters and flow sensors, as well as other manufacturer’s 
products which have frequency output proportional to flow. In 
addition to batch functions, the FT500-Series indicates flow rate, 
and other data in large 3/8” (9.66 mm) digits on an easily-read, 
backlit display. Units of measure are user selectable, and range 
from milliliters per second to millions of gallons per day. The unit 
can be 110 Vac powered with a standard 3-wire cord (included), 
220 Vac powered (optional), or DC powered through an internal 
terminal strip (battery not included).
passive loop configuration, and in 0-5 Vdc or 0-10 Vdc outputs, 
and can be used in applications such as flow rate logging. Two 
programmable pulse scaled outputs are also standard, and can 
be used, for example, to provide proportional chemical feed with 
a pulse-responsive metering pump.
The housing is supplied with two brackets for wall-mount 
applications, or the top/bottom housings can be easily 
separated and reassembled for panel-mount.
In Batch Processing Mode, the display indicates a flow rate on 
the top line, and one of three user-selectable configurations 
on the bottom line: an accumulated total flow (resettable), ac-
cumulated batch flow, or batch process bar graph. The batch 
output is controlled via two relays. The main relay starts and 
stops the batch as a set, or the auxiliary “prewarn” relay can 
be used to operate a second valve. This allows increased ac-
curacy by engaging a staged shut off at the end of the batch.
