Explain the meaning of the term interface.

List two reasons why it is essential to monitor the level of material in a container. Explain the meaning of the term interface. List an indicator method used for level measurements that does not provide a feedback signal. Name a common mechanical instrument used to measure the level of solid materials. Where is the pressure detector placed in a vessel to measure the level of a liquid? Water is stored in a vessel at 60 degrees Fahrenheit. A pressure gauge at the bottom of the tank reads 40 psi. What is the height of the water?
