A widely respected non-profit association, WIB (Working-party on Instrument Behaviour), recently conducted a series of tests to determine if guided radar is actually a simple and reliable technology to replace expensive and high maintenance intensive displacer type of measurements in bypasses or sight gauges for level monitoring.

WIB was originally set up in Europe and, over the past 42 years has been providing independent reports on how well an instrument meets the manufacturer's claimed specifications.

WIB's tests were performed on a rig with multiple by-passes or bridles at the Dow Chemical plant in Terneuzen in the Netherlands. Several leading suppliers of guided radar instruments participated: two German, two American and Endress+Hauser .

Levelflex from Endress+Hauser was one of the top performers in these tests. The test team was impressed that Endress+Hauser could measure low dielectric constant fluids with a single rod, without the need for coaxial probes.

WIB also highlighted the end-of-probe (EOP) algorithm of the Endress+Hauser device that provided excellent results in demanding applications with low dielectric constant fluids.

WIB comprises instrument manufacturers as well as large end users such as Dow, Heineken, Dutch State Mines (DSM), Shell, DuPont and tests instrumentation under process conditions.

It is an independent international initiative and often tests a specific group of instruments from various suppliers to compare performance.
