Multivariable transmitter redesigned for optimal gas-flow measurement

Invensys Process Systems has redesigned its Foxboro-IMV25 multivariable transmitter. It’s targeted for optimum natural-gas flow-rate measurement and other natural gas applications needing accurate measurement of pressure, differential pressure, and process temperature. IMV25s are now available with: Modbus digital communications for remote monitoring, configuration, and calibration; a new process interface structure for flexible installation; extended measurement ranges; and what’s claimed to be the industry’s longest standard warranty.

The Modbus version communicates with host processors using the Modbus RTU mode via two-wire, RS-485 multidrop serial-connection, providing high data-throughput at common baud rates. IMV25 is also available with HART and FoxCom communications, as well as an assignable, 4-20 mA output signal.
