Magnetic flowmeters for pulp and paper industry
May 2003
Flow Measurement & Control
The accurate measurement of paper pulp is well known as a problematic task, particularly when the liquid cannot be filtered and long fibres are present.
DLM is offering the ISOMAG Millennium, manufactured by Isoil Industria, as an answer to this problem. The instrument features a programmable on-site sampling frequency selection from 50 to 80 Hz, available as standard in sizes up to 300 mm.
In practical terms this feature means that the sampling can be carried out at a maximum of 150 samples per second or at an interval of 6,7 ms between two samples. This obviously allows the end user to select the frequency most suited to the media being measured thus providing the best accuracy and repeatability possible even in the harshest applications. The flowmeter is available with screwed, flanged, wafer or hygienic Tri-clamp and Tri-clover fittings certified 3A. A large variety of electrode and lining materials is also available.
DLM, one of southern Africa's leading innovators in the engineering of over- pressure protection; flow, level and density measurement; automation and control solutions. The company offers a comprehensive, technologically advanced range of products sourced from the world's leading manufacturers, providing optimum solutions in a wide range of industries. DLM has seven branches countrywide - in Cape Town, East London, Pinetown, Rustenburg, Welkom and Vereeniging - in addition to its headquarters in Longmeadow, just outside Johannesburg.

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.

Case History 197: Bad reboiler temperature control.
Michael Brown Control Engineering
Editor's Choice Flow Measurement & Control
It is very important that reboiler temperature controls operate well in petrochemical refineries, or the product quality can really suffer. I was asked to check such a control in a refinery where they were having problems with one of these controls.
