Frothy lager is a level challenge
3 May 2000
Kronenberg beer, producing premium lagers at its facilities in Champigneulles, France, was faced with a problem of excessive foaming which affected the level detection device on storage vessels. Too much oxygen in the product resulted in excessive foam occurring in the storage tanks so three smaller vessels were added to fulfil a degassing process. Initially, traditional tuning fork level devices were installed to measure the levels in the degassing tanks, but the excessive layers of foam resulted in incorrect liquid level measurements.
Kronenberg specified Magnetrol Echotel 915P ultrasonic level switches and Definox valves to help control degassing. The contacts switches were not fooled by the foam and correctly sensed the liquid level. The ultrasonic switches are designed to detect high or low level alarm across a variety of liquids, including viscous or light liquids and also offer ultrasonic control.
