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 with 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.
