Calibration with 0,00% deviation? – Too good to be true!

Is every calibration report a true indication of the performance of my measurement equipment? Most of us would like to answer this question with a clear “Yes, Sir!” Read about an example out of the daily life of a calibration lab, that will make you think.

Basics about UVC (Universial Viscosity Calibration)

Like any measurement instrument, a turbine flowmeter is sensitive to various effects, for example to the viscosity, as well as density and velocity. Following is a brief discussion of the sensitivity of a turbine flowmeter to viscosity and the description of a method (UVC) which can be used to compensate its effects.

How much do you trust the accuracy specifications of flowmeters?

Flowmeters are often chosen according to the specifications, as listed in the documents supplied by the manufacturers. Later, under actual operating conditions, customers are often disappointed with the measuring results, which are obviously not within the stated specifications. What is the reason for this? Are the suppliers giving wrong statements?

Why is my Flow Meter more and more inaccurate after some time?

Time plays a big role in the accuracy of flow meters. All flowmeters tend to drift gradually over time and sometimes unbeknownst to their user, influence the measurement process. What are the reasons and how can they be met?

How often should we calibrate our Flow Meters?

This question is frequently asked to the staff at TrigasFI GmbH in Neufahrn near Munich. And it’s a good question, because in the age of ISO 9000 and increased quality demands, it is important that all measurements of physical quantities that are part of an industrial process are accurate and reliable. Are there general suggestions? How can a user deal with this?

High accuracy measurements with flow studies from TrigasFI

Irregular flow profiles due to bends, obstacles or other flow disturbances often cause significant measurement errors. In these cases, the general purpose recommendation of an optimal installation depth and insertion angle is not sufficient. How can accurate readings be achieved in difficult applications?
