Content

Description

Process instrumentation is all about measuring, recording and controlling the necessary parameters involved in an action. Hence it is important to maintain a greater level of precision in this process.

This course gives a complete idea about process instrumentation, various types of measurements involved depending upon the situation and instruments used for this purpose.

After completion of this course, students will get a wider and clear idea about level, pressure, temperature, flow measurement and also about smart transmitters.
