Flow measurement

NT500 batch controller

The NT500 controls product loading and unloading at oil depots and on custody transfer lines. It works with almost any flow meter, and can read temperature, pressure and density to correct the quantity delivered. The operator sets the amount; the NT500 runs the pump and valves and stops on the preset.

  • Single-arm or multi-arm loading
  • Works with almost any pulse-output flow meter
  • Drives two-stage, multistep or 4-20 mA control valves
  • Connects to SCADA or a terminal automation system over Modbus TCP
  • Stores over 100,000 loadings and prints delivery reports
  • Explosion-proof: Ex d[ib] ib IIB T4

How it works

Set it, load it, stop it.

  1. Set

    The operator picks the product and enters the preset, on the keypad or from the terminal automation system.

  2. Load

    The NT500 checks the interlocks, opens the valves and starts the pump. It counts the flow and watches flow rate and temperature while product is delivered.

  3. Stop

    Near the preset it drops to low flow to avoid splashing, then closes the valves and stops the pump on the exact amount. The delivery is stored and can be printed.

Where it is used

Typical applications.

  • Truck loading bays
  • Oil depots and terminals
  • Custody transfer lines
  • Additive injection during loading
