266CSH-F3KB6J1-V1E1L5B1I2: 266CSH multivariable transmitter: flow compensation and configuration planning
The ABB 266CSH is a multivariable transmitter that calculates compensated mass flow from differential pressure, absolute pressure and temperature. ABB identifies gas, vapor and liquid flow applications for the family. The listed configuration string is retained for identification, but the exact sensor limits, flow element and output protocol require the matching order record.

The table summarizes family or catalog values for identification and initial selection. Confirm the nameplate, environmental limits, standards, revision and options for the exact device before procurement or engineering approval.
Application and system selection
A multivariable flow calculation depends on both the transmitter and the primary element. Confirm pipe size, orifice or other flow element, fluid properties, operating envelope, pressure/temperature inputs and compensation method. Review turndown and uncertainty across the full operating range, particularly when process composition or conditions vary.
Configuration and compatibility
Verify each input sensor, range, engineering unit, output protocol, approval and configured flow calculation. Check whether the host receives a compensated flow value or individual process variables and confirm register/device-description compatibility. Do not substitute a single-variable 266 model for the multivariable function without redesigning the measurement loop.

Installation and commissioning
Install the pressure connections and temperature sensor in accordance with the primary-element design and ABB instructions. Check impulse-line routing, leak integrity, heat conduction and pressure taps. Commission all three variables against references, validate the calculation and output scaling, then compare indicated flow with the approved process or calibration method.
Replacement and procurement information
For a quotation or replacement review, provide the complete designation 266CSH-F3KB6J1-V1E1L5B1I2, the order code where applicable, serial or hardware revision, quantity, operating environment, connected equipment and required delivery date. Include a legible nameplate image and relevant wiring, loop or switchgear drawing so the exact interface and configuration can be checked.
Ask the supplier to confirm accessories, revision compatibility and any approved successor in writing. Do not select solely from a family name or product photograph. Follow the current ABB installation and safety instructions for the exact unit.
