Multi-variable transmitter

December 20, 2005

Invensys Process Systems has redesigned its Foxboro IMV25 multi-variable transmitter for natural gas flow rate measurement and other natural gas applications that rely on measurement of pressure, differential pressure and process temperature. The IMV25 product line is available with modbus digital communications for remote monitoring, configuration and calibration; a new process interface structure for flexible installation; and extended measurement ranges.

The IMV25 allows remote monitoring, configuration and calibration. The modbus version communicates with host processors using the modbus RTU mode through a two-wire RS 485 multi-drop serial connection. The IMV25 is also available with HART and FoxCom communications.

A configurator software package for Foxboro modbus multi-variable transmitters, model PCMM, has also been introduced for transmitter setup. Communications are accomplished through either a serial or USB-to-RS485 converter.”Transmitters can be mounted directly to a three- or five-valve manifold assembly, supported by the process piping.
