IM 119 NON LINEAR LEVEL CONTROL

DESCRIPTION

 

Non linear level control is designed for understanding the principles of non linear level control. The process setup consists of SS spherical tank, and conical process tanks and supply water tank with pump for water circulation. A pneumatic control valve with I/P convertor manipulates the water flow in to the process tank. These units along with necessary piping are fitted on support housing designed for tabletop mounting. Level transmitter is used for sensing level in the process tanks.

The product interfaces with computer through NI USB DAQ card and controlled by specially developed control software.
