Flow Computer Hays Series FT520
 The FT520 is a hatching flow processor with additional output features. It 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 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 auxillaryÓprewarnÓ 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.
