Seametrics FT520-86 Instructions

General Information

The FT520 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 is a set of user-
configurable alarm relays which can signal when a
maximum or minimum flow is reached. Applica-
tions tyically include detection of a pipeline failure
or of a pump that has run dry. The dual relays can
be connected to an alarm, auto dialer, or any other
switch-controllable device.
In addition to the flow rate alarm, the FT520 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.
