 Hays
Flow Computer Series FT520 is a hatching flow processor with
additional output features. Hays Flow Computer Series FT520
is designed for use with Hays Fluid Controls flow meters and
flow sensors, as well as other units which have frequency
output proportional to flow. In addition to batch function,
the Hays Flow Computer Series FT520 indicates flow rate and
accumulated total in large digits on an easily-read backlit
display Units are user selectable and range from milliliters
per second to million gallons per day Batch output is controlled
by two relays. The main relay starts and stops the batch asset.
The auxillary prewarn relay can be used to operate a second valve, in order to have a staged shut off at the end of the batch, for maximum accuracy. Analog output (4-20 mA, 0-10 VDC) is included for applications requiring it, such as flow rate logging. Two programmable pulse outputs are also standard, and can be used, for example, to provide proportional chemical feed with a pulse-responsive
metering pump.
