Evaluation International are pleased to announce the establishment of a national EMPHASIS ASSESSMENT register which is being made available to Evaluation International Member companies.  This register brings together all planned, in-progress and complete Emphasis Assessments, undertaken on behalf of the Sponsor Companies. 

In addition to this Evaluation International has established a Working Group to oversee the development of the Register and supporting services. Any organisations wishing to access the register or participate in the working group should email: enquiries@evaluation-international.com and a member of our team will be happy to assist.



Evaluation International has bilateral agreements with both EXERA and WIB. These agreements enable EI member companies to access the reports produced by these associations and to collaborate in working groups and projects. 

In addition, EI participates in a wider consortium of end-user organisations across Europe with member companies that operate on a global scale. The aim of this consortium is to ensure that the widest possible community of large-scale EC & I end-user organisations are provided with a platform on which to share knowledge, network, collaborate and share.

The consortium includes the following organisations:


EXERA – the French end-users association for industrial automation. [https://www.exera.com]
WIB – a process automation users association covering the Netherlands and Belgium. [https://www.wib.nl]
CLUI – the Italian Association for Automation and Instrumentation Systems. [http://www.cluias.it]
NAMUR – the German end-user association of automation technology and digitalisation in process industries. [https://www.namur.net]

Endress+Hauser level meter Levelflex FMP54


This report describes an evaluation of an Endress+Hauser (E+H) Levelflex FMP54 Guided Wave Radar (GWR) designed for high-temperature (-196°C to +450°C) and high pressure (-1 bar to 400 bar) applications. The special feature of the evaluation is that the reported tests of the level meter were performed under high operating pressure conditions (up to 350 bar). The overall objective of this test report is to confirm that some specific data stated and published by the manufacturers is correct and valid. This, in combination with statistical testing and functional tests should be seen as a guide for the selection of devices for a specific application. A special feature of the Endress+Hauser Levelflex FMP54 is that the device has integrated automatic gas phase compensation. The principle of automatic gas phase compensation adopted is to present a target at a fixed distance along the waveguide where a step decrease in diameter creates a radar echo at a known physical distance. The purpose of the test was to prove the effectiveness of automatic gas phase compensation when applied to high pressure hydrocarbon gases above a hydrocarbon liquid.
