TransitTime Flow Measurement
Transit time ultrasonic flow measurement is based on the principle of sound energy traversing the fluid or gas in a pipe both upstream and downstream where the time difference is impacted proportionally depending on the flow rate.
Still Going Strong – Why Venturi Tubes Continue to Enjoy Enduring Popularity in the Oil and Gas Industry
Despite being based on technology which is over 100 years old, Venturi Tubes continue to be a widely applied form of flow measurement in the Oil and Gas Industry. In this article, Harry Lawrence, Flow Product Manager for ABB Limited, explains the basic principles involved in the measurement of flow using differential pressure (DP) producers and the reasons for the enduring popularity of the technology for Oil and Gas applications.
Thermal Flow Switches For Water Treatment In Oil Refineries
Reliable monitoring and treatment of water in oil refineries is essential for the production of petroleum-based products, including gasoline, diesel, kerosene, heating oil, and byproducts for plastics and a variety of lubricants (Figure 1). There are three process areas within refineries that require large amounts of water: cooling units, desalter units and wastewater treatment.
