MacMAT IV Flow Computer
4Pages

Flowcomputer MacMAT IV is a key element of safe and precise measuring systems for flows of large volume of natural gas. It guarantees safety of work, data security and interference protection, as a result of more than 25 years of experience in volume correctors and flowcomputers development. MacMAT IV is equipped with intrinsically-safe, explosion-proof measuring inputs as well as binary inputs allowing to connect devices from Ex-Zone. has IP65 protection class, and provides high level of electromagnetic compatibility (EMC). The device also has a redundant power supply system. Measuring circuits provide long-term high stability and they combine functionality of digital communication interfaces to cooperate with transducers and flowmeters. MacMAT IV is designed for direct co-operation with gas meters: ultrasonic, mass, turbine, rotary, and external chromatographs and calorimeters. Built-in 100 Mbps Ethernet interface and quick serial RS485/RS422 port working with baud rates up to 460 kbps allow to an easy integration with IT systems. Distinguishing features of MacMAT IV • • • 64-bites processor with pipelining allows to on-line work in 250ms cycle with real calculation all of computation algorithms Device has intrinsically-safe measuring circuits, which can be connected direct in explosion-proof areas High efficiency redundant communication channels with external SCADA, DSC, PLC systems, ultrasonic gas meters, gas chromatographs: Ethernet port, four galvanically insulated serial ports RS485/422, local communication in infrared is proper with IEC 62056-21, USB host, intrinsically-safe galvanically insulated four HART modems Multilevel access for administrators and users via built-in WEB server, supporting advanced configuration and mapping measurements variables between cooperating devices PLUM Ltd.
