Non-Contact Level Gauge Performance (Part 1 of 4) by David W Spitzer and Walt Boyes

The purpose of installing a level measurement system is to measure level accurately in a reliable manner. Whereas issues dealing with physical properties, process parameters, electronic features, and interconnections are often considered extensively, the quantification of the expected measurement quality of the installed level measurement system can be virtually neglected.

Considering Your Components: The Many Elements of a Flow Measurement System by David W Spitzer

Flow measurement systems are often composed of a number of components that can have different performance specifications. This is especially applicable for flowmeters in which the flow measurement system consists of components that are designed and manufactured separately.

Which Meters Use the Principles of Differential Pressure? by David W Spitzer

Differential pressure flowmeters are readily available and are used extensively in industry. In particular, there are many orifice plate, Venturi flow tube, and flow nozzle installations. Which of the following flowmeters use differential pressure flowmeter technology in the sense that their operation is reflected by similar equations?


In addition to over 40 years of experience as an instrument user, consultant and expert witness, David W Spitzer has written over 10 books and 500 articles about flow measurement, level measurement, instrumentation and process control. David teaches his flow measurement seminars in both English and Portuguese.
