In recent years acoustic flow measurement and flow metering has established itself as the standard method for measurement in many hydrological stations but is also used as the basis for various applications, for example for flood protection and flood forecasting. Ultrasonic flow meters are also used in hydro-engineering constructions. With this almost contact free technology data can be recorded continuously and it provides 24/7 monitoring. Such flow monitoring is particularly important in waterways used for shipping, transportation, irrigation, drainage and for cooling water extraction of power plants. A further important use of transit-time open channel flow meters is the transportation of water used for the supply of drinking water. Here the focus lies on detecting the flow rate of water loss at an early stage as it is sometimes difficult to detect small leakages.

Monitoring process streams and waste streams continuously in a brew house can provide many benefits to operations. Monitoring product in process for color or concentration provides consistency and quality measures. Product loss can be quantified by monitoring waste streams. Processes can be improved to increase efficiency and minimize effluent waste. Effluent waste streams can also be monitored for organic loading with BOD and COD correlations to ensure compliance for discharge.

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.
