General Information
The FT522 is a flowmeter monitor with added
output and alarm features. It is designed for use
with SeaMetrics flow meters and sensors, as well
as other units which have a pulse or frequency
output. It displays flow rate and total in large digits
on an easily-read backlit display. Units are user
selectable between gallons, cubic feet, and cubic
meters.
The primary output of this unit is a user-set alarm
relay which signals excessive total flow within a
given time period (up to 48 hours). This is typically
used to detect an elevated usage level in a cooling
tower or potable water application. The dual relays
can be connected to an alarm, autodialer, or any
other switch-controllable device.
In addition to the usage alarm, the FT522 has
analog output (4-20 mA, 0-5 VDC or 0-10 VDC)
and programmable pulse output. These can be
used for data logging or to provide proportional
chemical feed, using an externally-controlled
metering pump.
