Krohne Proved: Expect More – Achieve More.

Jan 01 2000

Every KROHNE meter gets a thorough inside-andout check before it leaves any of our factories in Germany, Europe, or overseas. We give the name “KROHNE proved” to the specific trials, measurements, tests, and material testing we do. Our testing goes far beyond what is legally mandated to ensure that our products not only function properly within the guaranteed temperature coefficients, but withstand even the toughest conditions.

We subject every meter to a entire series of comprehensive temperature change tests. The electronic elements are placed in climate-controlled cabinets and put through cyclical temperature changes from -20° C to +60° C. This minimizes failures in the field.

All of our flowmeters are subjected to wet calibration by direct volume comparison. Our calibration process employs the most accurate calibrating rigs on the planet. This provides our customers with the maximum level of safety and security and guarantees the accuracy readings for all flowmeters under reference conditions. Of course, all level meters are also checked in a calibration process consisting of several tests, some of which employ calibration towers more than 30 meters high.

We will not relax any part of our stringent testing programs in the future. After all, we want to precisely know the quality and performance of every unit before it goes out the door to our customers.

The worlds largest calibration facility for electromagnetic flowmeters and ultrasonic flowmeters in Dordrecht, Netherlands. 44 metres high, almost half a million litres capacity, maximum flow rate more than 1/2 million litres per minute, 0.013% calibration volume uncertainty.
