ABB Measurement Products 266 multivariable transmitters directly calculate the mass flow or standard volume flow for gases, vapors and liquids with dynamic flow compensation from differential pressure, absolute pressure and temperature; they correct for parameters such as the discharge coefficient, thermal expansion of pipelines and primary device, and the Reynolds number. The transmitters also measure the level of liquid-filled tanks and boiler drum level with temperature and/or pressure dependent density changes of the process medium.
