Description

The Conical & Spherical Tank Level Process Trainer is designed to understand the elements of a non- linear level process and its control. It consists of conical and spherical process tanks fitted with a level transmitter and necessary drain valve arrangements. The inlet flow to the tank is controlled by a control valve which operates on a 3 to 15 psi pressure signal. A current to pressure (I/P) converter is used to convert the output of the controller (4-20mA) to the signal pressure. The process parameter is controlled by a
microcontroller based digital indicating controller. These units along with necessary piping are fitted on the support frame. The setup is designed for tabletop placement and access. The controller is connected to computer through USB for monitoring and controlling the process. User friendly software will be supplied along
with the hardware to perform different set of experiments.
