State of Technology Report: Level Instrumentation

Focuses on expanding applications and solving problems with using conventional technologies in existing applications.

By Paul Studebaker

Simple in concept, measuring the height or quantity of solids and liquids in tanks and vessels is amazingly complex in practice because there is a virtually infinite number of combinations of materials and operating conditions under which they must be measured. Solving the resulting problems with agglomeration, separation, corrosion, foam, vapor and adhesion, as well as high and low pressures and temperatures, etc., has resulted in markets for many niche as well as broad applications for a wide variety of instrumentation.

Every few years, advances in manufacturing and signal processing bring a new technology, such as laser, into the practical realm of industrial applications, but for the most part, today’s fundamental technologies of level instruments and switches—float/displacer, differential pressure (DP), capacitance/admittance/conductance, vibration, magnetostriction, radar, laser, nuclear, weight—are well established.

Download the 2016 State of Technology: Level Instrumentation, which focuses on expanding applications and solving problems with using conventional technologies in existing applications.

Topics include:

  • How to deal with (or eliminate) DP impulse line problems
  • Control oil/water interfaces
  • Improve boiler drum level control
  • And much more.
