B+S Process Instruments

The drive to make manufacturing processes more efficient has created the demand for in-line instrumentation. This new division of Bellingham + Stanley was established in the late nineties to focus on the particular needs of in-line monitoring and process control.

On-line applications extend from simple interface detection and final concentration recording at the filler of a juice packaging line to the monitoring of sugar blend ratios in confectionery plants. Latest In-tek (in-line) systems provide continuous monitoring and control of engineering fluids in bulk storage tanks and provide the basis of our effluent systems.


Having been family owned for almost a Century, in 2007 Bellingham + Stanley was acquired by Nova Analytics to become a part of  a larger group of companies including leading brands such as WTW, ebro electronic and the newly named SI Analytics, all servicing the world of Analysis.

In 2010, ITT Corporation acquired Nova Analytics. and integrated it as ITT Analytics. ITT Corporation was a high-technology engineering and manufacturing company operating on all seven continents in three vital markets: water and fluids management, global defense and security, and motion and flow control.

On 31st October 2011 ITT corp. split into three companies, with Bellingham + Stanley playing an important role in water business, Xylem Inc.
