ABB Flow-X/M modules Flowcomputer
Overview
ABB Flow-X/M is the core module of the Flow-X family. Each /M is a complete single-stream flow computer with precision I/O, dual-pulse proving support and robust reporting, designed for custody/fiscal metering. It installs in panel, rack or field enclosures and can be configured locally via touchscreen or remotely through a secure HTTPS web server.
Key Features
Single-stream core: Each Flow-X/M is a full flow computer for one meter run; multiple /M modules combine inside Flow-X/P for multi-stream stations.
High-accuracy I/O: Precision AI and pulse inputs (incl. dual-pulse proving) for demanding fiscal applications.
Standards & calculations: AGA/API/ISO plus GERG-2008 for natural gas; liquid density/energy options by configuration.
Interfaces & usability: Local touchscreen (model-dependent) and secure web UI for configuration, monitoring and diagnostics.
Scalable enclosures:Flow-X/P for 1–4 streams with local HMI, Flow-X/S for compact single-stream, and Flow-X/C standalone options.
Technical Highlights
Analog inputs (typical ranges mA/V) with very low error; high-resolution pulse inputs for turbine/PD/orifice/Coriolis/ultrasonic meters.
Dual-pulse double chronometry proving support, hourly/daily/monthly reports, extensive event/parameter logs.
Industrial comms (per build), security/user roles, and audit-friendly data retention.
Wide ambient rating; EMC/EMI-hardened design for harsh sites (exact ratings depend on variant).
Applications
Custody transfer & fiscal metering (gas and liquid)
Pipeline metering stations and terminal loading/LACT skids
Multi-stream stations using Flow-X/P with multiple /M modules
Brownfield replacements where precise I/O and modern web access are required
Compliance & Standards
AGA/API/ISO calculation libraries; GERG-2008 for gas compressibility; reporting and data integrity suitable for audited metering systems (final approvals depend on model code and enclosure).

Technical Overview
The ABB Flow-X/M is the core computation module of ABB’s SpiritIT Flow-X series flow computer platform, used for accurate flow calculation from multiple sensor inputs across oil and gas custody transfer and general industrial flow measurement applications. Per ABB’s official datasheet, the Flow-X/M module is built around a 32-bit microprocessor with a dedicated math coprocessor and FPGA, providing 1 GB of onboard memory for time-stamped historical and event data logging, and a real-time clock accurate to 2 ppm. Analog input accuracy is specified at 0.002% at reference (room) temperature, reflecting the high-precision requirements of fiscal/custody-transfer flow measurement.
The module accepts 6 analog transmitter inputs (supporting 4–20 mA, 0–20 mA, 0–5 V, or 1–5 V signal types) at 24-bit resolution, 2 four-wire PRT temperature inputs, and 4 independent HART loop inputs with multi-drop support, along with 16 digital inputs (100ns resolution), 16 digital outputs, and 4 pulse outputs for interfacing with turbine, ultrasonic, or positive-displacement flow meters. Specialized input types support density/viscosity meters, sphere detectors for pipeline prover systems, and prover-bus configurations used in meter proving verification. Communication is available via 2 RS485/RS232 serial interfaces and 2 Ethernet ports, supporting Modbus RTU/ASCII (Master and Slave), Modbus TCP, HART Master, and ABB’s proprietary Flow-X Client protocol.
The Flow-X/M module is available in several enclosure configurations: the Flow-X/S single-stream DIN-rail-mounted unit with LCD and screw terminals; the Flow-X/K compact single-stream unit with D-sub connectors; the Flow-X/P multi-stream panel unit supporting up to 4 modules with a 7-inch color touchscreen; and the Flow-X/R rack-mounted unit in 19-inch format supporting up to 8 modules for large multi-stream metering stations. The platform supports the full range of industry-standard flow calculation methods, including AGA5/7/8/10 and GERG-2008 for gas, API 5/6/23/24/53/54/59/60 and GPA standards for liquid, and ISO 5167/V-cone/AGA3 for differential-pressure flow measurement. Certifications include CE marking per EN 12405-1, OIML R117, WELMEC 7.2/8.3/8.8, and compliance with the EU Measuring Instruments Directive (MID) 2004/22/EC, reflecting the platform’s suitability for legally regulated fiscal metering applications. Operating temperature range is 0°C to 60°C, with power input of 20–32V DC (nominal 24V DC) at approximately 0.3A nominal consumption.
