The Seametrics FT500 Series is a batching flow processor with additional output controls. It is designed for use with Seametrics flow meters and flow sensors, as well as other manufacture’s products which have frequency output proportional to flow.

In addition to batch functions, the FT500-Series indicates flow rate, and other data in large 3/8″ (9.66 mm) digits on an easily-read, backlit display. Units of measure are user selectable, and range from milliliters per second to millions of gallons per day. The unit can be 110 Vac powered with a standard 3-wire cord (included), 220 Vac powered (optional), or DC powered through an internal terminal strip

batching system

An analog output of 4-20 mA is available both in active and passive loop configuration, and in 0-5 Vdc or 0-10 Vdc outputs, and can be used in applications such as flow rate logging. Two programmable pulse scaled outputs are also standard, and can be used, for example, to provide proportional chemical feed with a pulse-responsive metering pump.

The housing is supplied with two brackets for wall-mount applications, or the top/bottom housings can be easily separated and reassembled for panel-mount.

FT520 Batch Controller

In Batch Processing Mode, the display indicates a flow rate on the top line, and one of three user-selectable configurations on the bottom line: an accumulated total flow (resettable), accumulated batch flow, or batch process bar graph. The batch output is controlled via two relays. The main relay starts and stops the batch as a set, or the auxiliary “prewarn” relay can be used to operate a second valve. This allows increased accuracy by engaging a staged shut off at the end of the batch.

FT520-84 Filter Regeneration

In Filter Regeneration Mode, the display indicates a flow rate on the top line, and one of two configurations on the bottom line: an accumulated total flow (resettable), or batch process remainder. The regeneration process is initiated by setting a target volume, a value for regeneration time as well. A single relay or alternate relay setting allows control of either single tank or alternating dual tank systems.

FT520-86 Flowrate Alarm

In Flowrate Alarm Mode, the display indicates a flow rate on the top line, and on the bottom line, an accumulated total flow (resettable). The user sets a minimum and maximum flow rate, and if the flow exceeds the min/max parameter, Relay 1 or Relay 2 will close. The output relay will stay latched until the flow rate increases/decreases back between the min/max settings.

The output relay will stay latched until the flow rate increases/decreases back between the min/max settings.

FT522 Usage Monitor

In Usage Monitor Mode, the display indicates one of two configurations: an elapsed time and elapsed flow, or a flow rate and accumulated total flow (resettable). A time period is set to monitor for a set maximum total flow. If the total flow is reached within the set time, an output relay is closed. The output relay stays latched until the system either resets automatically after the set time, or is reset manually via the StartStop button. A reset condition clears the elapsed time and flow, but not the accumulated total flow.
