Secondary pressure containment in Coriolis mass flowmeters

Plant safety maintained in case of ruptured flow tubes


Unexpected pressure peaks or incorrect design specifications can spark pressure-related damage of the flow tubes of Coriolis mass flow meters, causing leakage and spillage. This is a safety risk especially with toxic or aggressive media.


OPTIMASS straight tube Coriolis mass flowmeters with secondary pressure containment retain the fluid in case of tube failure. Featuring a typical burst pressure of more than 100 barg / 1450 psig (optional 150 barg / 2175 psig), this second line of defence prevents leakage and mitigates harmful effects on the application environment.

Safety benefits

  • Second line of defence for plant safety: No leakage or product spillage if flow tubes fail due to pressure conditions

  • Secondary containment retains the fluid in case of tube failure

  • Increased occupational safety when handling hazardous fluids and high-pressure applications

  • Typical burst pressure of secondary containment of more than 100 barg / 1450 psig (optional 150 barg / 2175 psig)

  • Available for all OPTIMASS Coriolis flowmeters with single, twin or quad straight tube design 

  • PED / CRN approved secondary containment can also be provided
