About Us

Accuflow was founded by Ke-Tien (KT) Liu in 1994 with the idea of creating a new and innovative compact well test separator to advance the state-of-the-art in multiphase flow measurement for well testing. KT holds a PhD in chemical engineering from University of Wisconsin-Madison and pioneered several well test measurement methods that remain industry standards today, including water cut calculation by density and cyclonic gas-liquid separation.

Before Accuflow, KT worked for Chevron Oil Field Research Company (COFRC) as group leader on crude oil measurement, focusing on improving custody transfer and well test measurement accuracy. It was there that he developed and patented the water cut by density method for well test measurement. This method allows for the calculation of water content in liquid by interpolating the measured liquid density between the corrected oil and water densities. Chevron later licensed this method to Micro Motion, which provided the basis for their Net Oil Computer (NOC) product. Today, this method is widely available—either built-in or available as an option in every flow computer and Coriolis flowmeter transmitter.

He also developed and patented the cyclonic gas-liquid separation technology then known as the Chevron Multiphase Measurement System (CMMS). This cyclonic separation technology allows for highly efficient separation of gas from the flow stream by spinning it like a centrifuge, while using a fraction of the materials and footprint of a conventional separator. Today, many major oil producers and oilfield service companies still utilize variations of this design.

KT also obtained a patent on a method to correct mass flow and density in 2-phase gas-liquid flow in Coriolis flowmeters and was therefore one of the first to study the effects of entrained gas on their performance.

After leaving Chevron and becoming an independent consultant, KT saw opportunities to improve upon the CMMS design and started work on what would become the first 2-phase Accuflow design. A patent was filed and Accuflow was founded shortly after. Accuflow quickly gained traction in the industry, selling hundreds of separators in less than a decade, and became a trusted solution for well test measurement. Later, KT developed and patented the rest of our compact separator designs and water cut determination methods that we continue to utilize.

Today, Accuflow continues its dedicated pursuit of better, more optimal solutions in multiphase flow measurement and compact separator design. From KT’s early designs to the sophisticated ones we create today, innovation has always been at the core of everything we do. As new challenges arise and new measurement technologies emerge, we remain dedicated to developing groundbreaking solutions that set the standard in well test measurement.
