Instrumentation : Introduction to Level Measurement
This introductory course on basic level instrumentation process measurement will provide students with a review of level measurement and control for processes including symbols, terminologies and technologies needed to work in the field. Understanding a level loop and P&ID and basic wiring techniques will be covered along with how instruments communicate. Students will be exposed to hands-on training utilizing a process column/tank. All transmitters are Endress Hauser and support the HART communication protocol. The class will be a combination of classroom and hands-on training utilizing the ATN Instrumentation Mobile Training Unit with a working process with on-line instrumentation and controls.
This course requires a prerequisite: Introduction to Instrumentation.
At the end of this course, students should be able to:
- Understand, setup and use various types of level measurement devices and methods.
- Understand the difference between point level and continuous level measurement.
- Install, setup and check level loops per a P&ID.
- Be familiar with the basic principles of operation of a typical differential pressure meter to measure level in tanks.
- Be familiar with Hart 475 Communicator to configure an Endress Hauser Transmitters.
- Be familiar with the dynamic characteristics of a process with regards to level.
