Ceramic measuring tubes for electromagnetic flowmeters
Increased plant safety thanks to technically superior wetted material
Challenge
Flow measurement of acids, alkaline solution and abrasive slurries bring a complex range of requirements that call for the right wetted material. Thermal shock, stress and strain, vacuum and high pressure and corrosion make conventional plastic liners reach their limits, with all consequences involved for plant safety, e.g. leakage.
Solution
By using oxide ceramic flow tubes, KROHNE electromagnetic flowmeters (EMF) feature a technically superior material that is permanently resistant to corrosive and abrasive media, immune to temperature shocks and absolutely safe against gas discharge, leaks and vacuum. As a flanged meter version with short bolts, it is the only ceramic flow sensor able to mitigate the impact of heat on the equipment in the event of fires.
Safety benefits
Extremely high performance and high durability ceramic flow tubes
Dedicated sealing concept with the flange non-wetted, enabling process safety
Very resistant to acids, e.g. even hot concentrated hydrochloric acid
High-resistance to abrasion
Increased fire safety: Mitigation of heat effects on flanged ceramic sensor version as compared to sandwiched versions due to small bolts
Leak tight-design, 0 % porosity (important for aggressive, outgassing or toxic media)
No cracks: fully vacuum resistant and high resistance to temperature shocks of up to
120 KVery high burst pressure/overload resistance
Adherence to the EU pressure equipment directive
EMF with ceramic flow tube and sintered cermet electrodes offer excellent long-term stability and accuracy for the highest application safety
