Product overview More information about the products: www.krohne.com/variablearea Web-based training for variable area flowmeters As part of the KROHNE Academy online we offer a variety of web-based trainings (WBT) including a WBT covering variable area flowmeters. Here you will learn all about the process including the measurement principle and sizing, design, advantages and limits of operation right down to applications and industries – and it’s all free and available for unlimited use.

Primary explosion protection by inertisation Measure inert gases reliably and cost-effectively Is it your task to guarantee explosion protection in your production while keeping a watchful eye on costs? KROHNE variable area flowmeters provide you with an economical and reliable solution for the measurement of nitrogen used in the inertisation of process tanks and other systems. Whether it is discontinuous purging or permanent blanketing, with reliable measurement you can optimise inert gas consumption and guarantee explosion protection at the same time. “Measures that inhibit the development of explosive atmospheres are to be implemented before all other explosion protection measures.” See ATEX 1999

As much as necessary Explosion triangle Limiting oxygen concentration Residual oxygen in vol% For many gases the limiting concentration is about 8-10 volume per cent, with hydrogen and carbon monoxide it is even less than 4 vol%. Carbon monoxide Nitrogen is generally used for inertisation and its throughput can be monitored reliably and cost-effectively with variable area flowmeters. Reference value fire protection During inertisation the oxygen in the air is at least partially replaced by inert gases, usually in a limited volume, so that the limiting oxygen concentration is not exceeded...
