It utilizes the HART communication protocol. A controller with a minimum of three inputs and two PID loops capable of both cascade and feedforward control and a 4-20 mA calibrator are also necessary. As both cascade and feedforward control schemes are used, the Advanced pressure, flow, and level process add-on (3530-M), is required.
