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).

Choosing Your Enclosure

• Flow-X/M — single-stream core module (this product)

• Flow-X/P — panel/rack enclosure with HMI to host 1–4 streams (multiple /M modules)

• Flow-X/S — compact single-stream enclosure (space-constrained sites)

• Flow-X/C — standalone configurations for specific station needs

FAQ

Q1: What exactly does a Flow-X/M module do?

It is a complete single-stream flow computer with precision I/O, fiscal calculations and reporting; multiple /M modules can be combined in /P enclosures for multi-stream stations.

Q2: How is /M different from /P and /S?

/M is the core module; /P hosts multiple /M modules (1–4 streams) with a local HMI; /S is a compact single-stream enclosure.

Q3: Does Flow-X support GERG-2008?

Yes—GERG-2008 for natural gas is supported in the Flow-X calculation suite.

Q4: Can I configure it remotely?

Yes—via a secure HTTPS web server, plus local touchscreen on supported enclosures.

Q5: Is the analog accuracy suitable for custody transfer?

Yes—the analog and pulse I/O are designed for high accuracy and stability required by fiscal applications (see exact error specs by variant).
