Water flow measurements for energy monitoring
Flow measurement of cooling water, chilled water and brine at the distillation columns’ heat exchanger
Cooling and brine flow measurement at distillation heat exchangers
In acrylic ester and polymer production, energy efficiency in distillation columns often has to be boosted to meet tightened emissions and industrial regulations. This can be reached by continuously monitoring the energy efficiency of the heat exchangers on the distillation columns. Flow measurements on the water circuits are needed for this task, with implemented technology needing to be able to handle the challenge of -15 °C methanol-water mixtures. If the uninterrupted operation of the acrylic plant needs to be ensured, retrofitting the measurement technology could potentially disturb production and cause too much effort and costs, therefore a non-intrusive solution was sought.

Product Solutions
The Flexim FLUXUS F721 is a technological breakthrough in the ultrasonic clamp-on volume and mass flow measurement of liquids. With its state-of-the-art hardware design and powerful digital signal processing it surpasses any other non-intrusive ultrasonic flowmeter in terms of accuracy, reliability and versatility. Highly sophisticated signal filters, faster than ever processing capacities and advanced measurement algorithms make the FLUXUS F721 liquid flow meter the standard setting measuring solution for any industrial application- even for the most challenging ones. The meter adapts itself automatically to the respective measurement conditions and compensates for flow profile disturbances such as beam dispersal and structure-borne noise.
