Electronic differential pressure system solves level measurement challenges at Lucite International

Engineers at Lucite International's Cassel Works in Billingham wanted a better way of measuring the level in a separator vessel. The vessel keeps the chemical BPA under vacuum and at high temperature to separate off volatile organics and reuse them, improving yield and plant efficiency. It’s important that the BPA itself doesn’t enter the downstream process due to its viscosity and high sulfuric acid content, which carries a risk of corrosion.

Lucite International chose Endress+Hauser’s Deltabar FMD72 electronic differential pressure system. Why? Electronic dp is 10 times more reliable and up to 10 times faster in response times than traditional capillary systems as it is independent of changing ambient conditions.

Ease of installation was also a big benefit. The system’s modular design means that the transmitter, sensors and cable are mounted separately, avoiding having to feed metres of cumbersome capillaries with attached flanges between floors or modify the vessel.
