FT520 Batch Flow Processor

Product Description
The 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 manufacturer’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. 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.
  • Large backlit alphanumeric display
  • Built-in 4-20 mA analog output
  • User-scaled pulse output for chemical metering pumps or telemetry
  • Two relay outputs for staged shutoff (batching) or dual setpoints (alarm option)
  • Rugged cast aluminum housing

    HaloSense Zero

    Key Benefits
    Many water companies want to measure free chlorine residuals without the need for chemical buffers traditionally associated with such measurements. Acetate and phosphate buffers are expensive and environmentally unfriendly. Buffer delivery systems are maintenance intensive and have fairly costly consumables and there are health and safety considerations in the handling of the acids and high disposal costs if the acid treated water is unable to be fed back into the water supply. Amperometric cells and most polarographic probes only respond to hypochlorous acid, (HOCl). HOCl dissociates into hypochlorite (OCl–) in a pH dependent manner. This is why most chlorine monitors need acid buffers in most applications. The typical pH of water measured on a water treatment works may range from 7 to 9.2. Chemical buffering reduces the pH to between 5 and 6 and ensures that the majority of the residual chlorine is present as HOCl (see graph below).
    • Low purchase cost
    • Low cost of ownership
    • Reduced pH dependency (largely pH independent)
    • Stable and reliable
    • Bufferless
    • Reagentless
