IND-I - Instrumentation Basics

The video tutorial covers the role of instrumentation in process control, focusing on measuring and regulating variables like temperature, pressure, flow, and level. It explains temperature measurement using Celsius and Fahrenheit scales, thermocouples, and RTDs. Pressure measurement is discussed with atmospheric and hydrostatic pressure, manometers, and pressure elements like bellows and diaphragm capsules. Flow measurement techniques include nutating disk, oval gear, and turbine flowmeters. Level measurement is explained through direct and indirect methods, using devices like sight glasses and differential pressure.
