Levelflex M gets a glowing WIB report
The Endress+Hauser Levelflex M guided radar level measurement device achieved excellent results in a recent report by WIB, the International Instrument Users Association
This single grain distillery produces around 70 million litres of alcohol per year.
Accuracy of volume measurement in the tanks is of prime importance at each stage of the process to satisfy HM Customs and Excise requirements.
Tanks such as spirit receivers, wash chargers, pot ale tanks, spent lees tanks, feints, receiver tanks and hot water tanks all require level systems offering an accurate volume measurement.
The previous system involved an operator taking manual dip measurements.
As well as being labour-intensive and time consuming, there were also discrepancies when the reading was taken by different individuals ie differing interpretations leading to inaccuracies.
Another problem was that over time the dip rods became bent or wear and tear resulted in inaccurate readings.
The solution was to replace this manual system with Endress+Hauser Levelflex M guided radar devices - both rope and rod versions were installed for safe and hazardous area use.
A trial probe was initially used in order to acquire approval from HM Customs and Excise via the 'proven in use' method.
After the success of the trial, Company Engineer John Sutherland decided that the Endress+Hauser Levelflex devices offered the best solution.
Via the Levelflex M display, vessel content can be viewed instantly.
Levelflex M uses high-frequency radar pulses guided along a probe to measure the distance between the process connection and the medium surface.
This can then be converted into a volume measurement +/- 3mm, independent of density or temperature.
Greg Muir, Company Engineer, stated: "The Endress+Hauser equipment was used because of its high accuracy and we no longer need to take manual dips.
This not only saves time but also removes the manual labour for the operators and makes the whole process more accurate and repeatable. Request a free brochure from Endress + Hauser ...
The system is now easily automated.".
