Air pollution emissions monitoring and control begins with accurate and reliable gas flow metering. There’s an old industry truism that says “You can’t control what you can’t measure,” and that applies here. Process plants install the world’s most sophisticated air pollution control systems, but they can be ineffective if the flow meters they rely on deliver inaccurate or unreliable data.
Isolation seals protect transmitters while faithfully conveying pressure signals. They enhance the measurement of not only pressure and vacuum, but also of derived variables, including flow rate, level, and density.
