In May this year Achema saw the unveiling of Variflux 6000, a high performance, sterile electromagnetic flowmeter from Krohne for use in a wide range of applications in pharmaceutical and chemical industries.
(a) With the sealing ring uncompressed, the trapezoidal form is clearly visible.
(b) When the meter is fitted and the sealing ring is compressed at room temperature, the greatest compression pressure is at the measuring tube end of the seal, forcing the seal to expand only into the expansion chamber.
(c) When the temperature is elevated with the meter fitted and the sealing ring compressed, the compression chamber is almost completely filled. The seal does not bulge excessively into the measuring tube
The flowmeter features a unique L-shaped sealing-ring with a unidirectional trapezoidal lip that unlike regular O-rings, eliminates the problem of bacterial growth by preventing expansion of the rubber seal into the measuring tube. Suitable for a broad variety of applications from ultra-precise batching to flow measurement in large-scale production plants, Variflux 6000 has an ultra-smooth tube liner made from FDA-approved Teflon PFA, which allows complete CIP and SIP. The measuring tube liner is reinforced with a stainless steel mesh, which ensures maximum stability and accuracy under varying pressure and temperature conditions.

Case History 198: Cascade control overcomes valve problems.
Editor's Choice Flow Measurement & Control
There are many processes where it is undesirable for the load to suddenly change quickly, for example in the paper industry. Examples of level control have involved reasonably fast tuning. An example of a level loop tuned this way and responding to a step change in setpoint is given.
