A California refinery produces xylene for use as commercial product and a precursor for petrochemical manufacturing. A primary component to the production of xylene is the isolation and purification of the chemical from a complex mixture of petroleum hydrocarbons. Steam based heat exchangers are used to process the xylene. Inherent to the design and rough duty heat exchangers face during their operation, leaks can and do develop. When a heat exchanger leaks, xylene contaminates the steam and produces a number of problems ranging from loss of final product, contamination and fouling of steam transfer piping, and ultimately bio-fouling of cooling towers. Consistent and reliable monitoring for xylene or other petroleum hydrocarbons in cooling water or steam condensate can alleviate product loss and process equipment down time.

In sewage treatment plants, flow sensors are primarily installed for internal reasons. Ultrasonic flow meters are used to control the flow velocity in partially filled and fulfilled pressurized pipes, specific plant components, for leak detection or to control the use of additives. International regulations such as the EU-Directive for handling municipal waste water require flow metering for a continuous surveillance of waste water flow. Defective flow monitoring in sewage-treatment plants can therefore influence their operation, but there can also be legal or environmental consequences.
