Title: How Safe Is Linearisation Of Flow Meters?

Abstract: For measurement instrumentation the golden rule of design is to optimise the basic mechanism, physics or design and then to use computers and signal processing to refine the concept and make it more useable. The essence is that the processing should be minimal to achieve the end performance. Linearisation is a particular area where this should be the major tenant of design. Unfortunately, a combination of the power of computer, digital signal processing etc. and the almost total integration of the basic structure of meters with processing has made the temptation to take a basically non-linear instrument and linearise it, without due recognition of the potential dangers for consistent measurement. It has also hidden from the user the extent to which these corrections are being carried out and masks the potential risks in operation. The requirements of any linearisation of a meter are that it should be minimal, and should have a stable, well defined reference, reducing the uncertainty of linearisation and ensuring stable operation under all possible conditions
