This article discusses the many different methods of fluid level measurement in industrial processes.

A novel method of probe-tip power calibration for S-parameters calibration is shown to greatly improve DC biasing and S-parameters measurement accuracy.

An economical TDR level-measurement system is achievable and can produce 0.02” resolution, self calibration and independence from fluid type.It provides information on the fluid composition, as well.

The magnetostrictive transmitters in ABB’s K-TEK level products are largely used worldwide to deliver nonstop level indication and transmission of an analog and/or digital signal for tracking or ...
