Overview

The Emerson 7958 (Solartron) – Klippon flow computer (PN 7958SAG34N9A) is a proven, panel-mount controller for liquid measurement where traceable totals, clear reports, and dependable communications matter. Delivered with Liquid firmware SW2550_108 (rev 2550lss1.08) and FC Config v2.5, it helps technicians commission faster, edit parameters safely, back up configurations, and export data without hassle. The Klippon terminal layout eases field wiring and maintenance; a built-in serial interface links the device to engineering PCs and supported printers for on-site diagnostics and routine reporting.

What you get in the package

This model ships with the controller assembled in the Klippon terminal arrangement, one serial communications cable, and the original CD containing FC Config v2.5, the 2550_108.00m/00u libraries, and PC configuration tools. The firmware listed above is already fitted, so you can focus on wiring, verification, and acceptance testing. Printing is supported—just confirm the exact printer model and cable before deployment.

Capabilities that matter in the field

Designed for brownfield sites and legacy panels, the unit provides stable liquid measurement, straightforward configuration workflows, and predictable report output. Parameters can be reviewed and adjusted with the supplied tools, while event and report routines help teams document changes and keep audit trails tidy. For day-to-day work, technicians will appreciate clear terminal labeling, simple I/O checks, and the ability to connect a laptop for quick backups or restores. Where sites still rely on serial engineering links and panel printers, this hardware/software bundle keeps operations practical and efficient.

Typical applications

This model fits custody-transfer or allocation liquid skids, pipeline and terminal loading with batch tickets, and replacements where the 7958 platform is already standardized. It’s equally useful as a shelf spare to reduce mean time to repair when a panel controller fails, helping plants avoid extended bypass conditions and resume protected operation quickly.

Compatibility & integration notes

Manufactured in the USA by Emerson, this Klippon-terminal version aligns with many installed Solartron-heritage panels. Before installation, match the terminal map to your panel drawings and confirm meter type, connected instruments, and any printer/cable requirements. For workstation connectivity, share your Windows/OS details so the appropriate driver guidance can be provided. If you’re replacing an older unit, back up the existing configuration first; the included tools assist with safe migration and validation after power-up.

Technical Specifications

Matching a Replacement to Your Existing 7958

On a metering skid, a flow computer is only a like-for-like replacement when the hardware, the connector style and the application firmware all match. Before ordering, check the installed unit for:

• The full part number on the rear label, compared character by character with 7958SAG34N9A.
• The connector arrangement – Klippon terminals or another style – since it decides whether the existing panel wiring can be reused.
• The application firmware and revision shown on the display or in the configuration report (liquid or gas application).
• The I/O actually used on site: pulse inputs, analog inputs, outputs and serial links.

If the installed unit runs a different application or revision, send us the details so the difference can be reviewed before the replacement is dispatched.

Commissioning and Metrological Checks

Load the saved configuration and then compare every parameter against the site’s approved configuration report rather than trusting the file alone. Typical checks before the stream returns to service:

• Meter factors, K-factors and product tables match the latest proving records.
• Pulse input integrity checks and alarm limits are active.
• Temperature and pressure inputs read correctly against calibrated references.
• Totals, batch reports and printed tickets are correct, with the clock set accurately.
• For custody transfer duty, the replacement is witnessed or sealed as required by the measurement contract.

Maintenance and Troubleshooting

• Totals drift from the meter or prover: check pulse cabling screens and earthing, and review the meter factor.
• No communication with the PC tool: confirm the serial cable, the COM port settings and the unit address.
• Printer produces no ticket: check the printer model, baud rate and cable wiring.
• Loss of configuration after a power interruption: investigate the internal backup and keep an up-to-date configuration file on record.

Applications in Oman and the GCC

Many crude, condensate and refined product metering systems in Oman and the Gulf were built on the 7958 platform and remain in daily service at export terminals, pipeline stations and loading racks. Keeping a matched spare with the right firmware on the shelf is often the most practical way to protect these metering systems until a planned upgrade.
