Plum - MacMAT IV / IVE - DC Powered Gas Flowcomputer

Plum_Flow_Computer_MacMAT_IV_IVEMacMAT IV / IVE is a flowcomputer dedicated for precise measuring systems for large volume flows of natural gas. Device is equipped with explosion proof, intrinsically-safe measuring and binary inputs which allows to connect to devices mounted in Ex zone.

Measuring circuits provide long-term high stability and they combine functionality of digital communication interfaces to cooperate with external transducers. MacMAT IV / IVE is designed for direct cooperation with gas meters: ultrasonic, mass, turbine, rotary, and external chromatographs and calorimeters.

Built-in 100 Mbps Ethernet interface and serial RS485/ RS422 port opearting on baud rates up to 115200 bps allows an easy integration with IT systems.

Advantages

-Industrial housing cooperates with various types of gas meter like turbine, rotary, ultrasonic, mass, directly by LF and HF inputs
-64-bit processor with pipeline processing allows on-line operation in 250ms cycle with real calculation of all of computation algorithms
-Pulse and analog intrinsically-safe inputs which can be connected directy to devices mounted in Ex zones
-3 Ex NAMUR type pulse inputs with wire continuity detection

-4 Ex galvanically insulated analog inputs with integrated HART modems
-2 none Ex binary inputs and 2 binary outputs with odorizer control
-6 none Ex independent communication ports (1x Ethernet, 3xRS485, 1xRS422/485, 1x Optical Interface IEC 62056-21)
-Support for extension modules EM-1, EM-2, EM-2Ex
