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.
