Measuring Tube Construction Affects the Long&#8211Term Stability of Magnetic Flow Meters

Overview:

Electromagnetic flowmeters, also known as mag meters, are popular and proven devices for flow measurement of electrically conductive process fluids and for volumetric filling machine applications. Of prime importance to a mag meter’s accuracy and long term performance is the condition of the metering section of the flow sensor.

Unlike in most processes, mag meters in filling machine applications are frequently subject to widely varying conditions during normal operation. As a result, they are viable candidates for evaluating their long term performance in an accelerated use environment. Therefore PTB, a German research and approvals agency, in association with KROHNE, undertook an extensive project to study the long term measurement stability of mag meters in filling machine applications.
