ABB Multivariable Transmitter type 266CRH and 266CSH

ABB Multivariable Transmitter with remote diaphragm seals calculates the mass flow for gases, vapors, and liquids with dynamic flow compensation directly from the three process variables of differential pressure, absolute pressure, and temperature.

The multivariable transmitters in the 266CRH are used for differential pressure flow measurements. Apart from pressure- and/or temperature-dependent changes to the density of the fluid, the parameters such as the discharge coefficient, thermal expansion of pipelines and primary device, and the Reynolds number are also corrected. It can also be used for DP level measurement if density compensation is necessary due to process temperature changes. This could make any level measurement much more reliable.

In addition to high precision, the multivariable 266 also offers the advantage that only a single device needs to be used for the measuring point instead of several transmitters and a flow calculator.
