Regulation of the PID

Our educational model of level control by PID uses exclusively industrial components.

Educational objectives
• Studying, putting into service, getting started and setting of the system
• Understanding and setting of the PID level regulation
• Calculating the span & zero offset of a level measurement by hydrostatic pressure of wet column. Adjust the level transmitter
• Wiring, putting into service & adjustment of components: transmitter, regulator …
• Make current measurements as in industry, without opening loops, with the help of a multimeter.
• Taking in hand the setting software of the frequency converter.

OPERATING PRINCIPLE
The objective is to adjust the water-level in a transparent polycarbonate column –diameter 160mm, height 1370mm. A pump draws the water from a 50-litre tank at the bottom of the column. The water constantly flows through the setting valve from the column towards the tank under gravity.
The PID regulator receives the “water-level” information from a 4-20mA sensor. It compares this signal with the level reference and controls the pump delivery via a frequency variator. The system operates in two modes: servo control and regulation. In regulation mode, a manual valve creates the disturbance.
