One of the long-standing philosophical questions of life is whether the light goes off in a refrigerator when the door is closed. For process engineers, an even deeper question is knowing what is happening inside pipes and tanks. The movement of fluids and the level of material within a tank is a mystery—unless you have the right technology and know how to use it. This edition of InTech Focus explains the basics of some remarkable technologies, including frequency-modulated continuous-wave radar, pulsed-wave or pulsed-width radar, ultrasonic level measurement, and more.
