Taking Advantage of Improvements in Level Measurement Technology

By Lydia Miller |

Level measurement technologies have become more versatile, robust and accurate thanks to recent developments. Differential pressure and radar level measurement provide examples Level measurement applications within the chemical and petrochemical industries can be extremely challenging. Level instruments must provide repeatable, reliable and accurate measurement of hazardous materials over wide temperature and pressure ranges, and with complicating factors, such as steam, dust, foam, turbulence and condensation. Solving the challenges of measuring the levels of fluids and solids in chemical processing applications is as old as the industry itself. Traditional methods, such as sight glasses and mechanical float switches or differential pressure (DP) level systems with wet- or dry-leg impulse piping, have all been used extensively and are still around today. But they can cause maintenance and reliability headaches, so many are getting replaced or augmented by more sophisticated methods. DP level systems are reliable when applied properly, and well understood, so they continue to be commonly used. Advances in technology have solved many of the difficulties caused by traditional impulse-piping based systems. Radar is another option for…
