Seametrics FT520-84 Instructions

General Information
The FT520-84 is a version of the SeaMetrics flow
processor specially designed for regeneration control.
On the input side, it can be used with SeaMetrics flow
sensors and meters, as well as contacting water meters
from other manufacturers. The output can be used to
initiate regeneration in a variety of one-tank and two-
tank water treatment systems. In addition to the
regeneration functions, this unit features displays of flow
rate and accumulated flow, as well as programmable
pulse output and a 4-20 mA analog output, for use with
remote recorders.
There are two regeneration relays, which can be used
for alternating regeneration of two tanks. The outputs
remain on for a duration programmed by the user,
depending on the requirements of the regeneration valve
being used.
A programmable pulse output can be used as needed to
control a chemical metering pump, for controlled chem-
ical addition to the water stream.
