OPTIMASS with tantalum

March 2009 Flow Measurement & Control

A corrosion resistant coriolis mass flowmeter.

Krohne has launched a new tantalum version of its OPTIMASS 7300 Coriolis mass flowmeter, to handle the highly aggressive and corrosive fluids found in the chemical industry.

Generally, the wall thickness of Coriolis measuring tubes are significantly less than the associated process piping, which will tolerate a higher rate of corrosion before failing. This is an area where wetted material selection for a Coriolis meter is critical.

Tantalum has been used by some Coriolis manufacturers in the past, but the twin bent tube designs made these expensive. This was due to the flange, flow splitter as well as the measuring tubes all being made from tantalum.

Krohne has applied its years of experience and been granted several patents for perfecting the technology of containing the stress created in a straight tube due to thermal expansion, and are now in a position to make this innovative technology available to highly aggressive and corrosive chemicals.

The new tantalum alloy (tantalum Ta10W) is made up of 10% tungsten and 90% tantalum. This has proved an ideal material for use in the OPTIMASS 7300 mass flowmeter as tungsten provides the additional tensile strength required to handle the stresses associated with straight tube technology.

“This is another innovation from our research and development team, who have employed over 15 years of experience in single straight tube design to harness this technology,” said Frank Grunert, global product manager for mass flow.
