Mass Measurement


High-pressure Coriolis flowmeter

October 2016 Mass Measurement

High-pressure processes for chemical injection systems, for example on oil drilling rigs or offshore platforms, are a challenge for any flow measurement system. Chemicals added by injection through a bore-pipe at high pressure directly at the wellhead increase water viscosity and enable efficient detachment of oil from the reservoir rock making its transport easier. In order to control the process, the injected chemicals must be measured accurately. Conventional volumetric systems such as gear or turbine flowmeters cannot be used for all media due to different liquid properties and big differences in density and viscosity, and do not provide the same results in terms of accuracy and reliability.

For these applications, Kobold Instrumentation, offers its reliable high pressure Coriolis flowmeters. The unique types of measuring loops, combined with special materials (different stainless steel versions, HP 160, Duplex) and heat treatment methods, allow users to work with operating pressures up to 1500 bar and extremely low flow rates from 1 kg/h.
