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 excess total flow within a given time pe-
riod (up to 48 hours). This is typically used to detect an
overly high 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, 0-10 VDC) and programmable pulse
output. These can be used for data logging or to provide
proportional chemical feed, using an externally-controlled
metering pump.
