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.
