ABB product families on this page
Flow measurement includes ABB electromagnetic, Coriolis, vortex and swirl meters, sold under names such as ProcessMaster, AquaMaster, CoriolisMaster and SwirlMaster. Liquid analysis covers pH, conductivity and dissolved oxygen sensors with their transmitters. SensyTemp TSP sensors handle temperature. On the electrical side the listing has ACS355 machinery drives, the ACS550 general purpose drive, the ACQ580 for water and wastewater and the ACS880-01 industrial drive, with fieldbus adapters such as the FPBA-01 for PROFIBUS DP. Protection and switching products include SACE Tmax XT molded case breakers, SACE Emax 2 air circuit breakers, PSR soft starters and the REM615 and RET615 relays.
Where ABB instruments and drives are used
Water and wastewater plants use the electromagnetic flowmeters, analyzers and ACQ580 drives together. Oil and gas, power and chemical plants specify the Coriolis and vortex meters, pressure and level transmitters and the 615 series relays for motor and transformer feeders. The drives run pumps, fans, conveyors and compressors in almost every industry.
Ordering ABB parts: what we need
For drives send the full type code from the rating label, for example ACS355-03E-05A6-4, plus the serial number if it is a replacement. For instruments send the complete order code, measuring span, process connection, wetted materials, output or protocol and the hazardous area approval. For breakers give frame size, rated current, breaking capacity, number of poles, trip unit and fixed or withdrawable version.

Frequently Asked Questions
How do I read the type code on an ABB drive?
The type code on the rating label identifies the exact unit. In ACS355-03E-05A6-4, ACS355 is the product series, 03E the construction (three-phase input with EMC filter), 05A6 the rated output current of 5.6 A and the final 4 the 400 V voltage class. Option codes may follow after a plus sign. Send the complete string so the replacement matches.
What replaces an ABB ACS550 or ACS355 drive that is no longer produced?
ABB publishes a life cycle statement for each drive generation. The ACS550 moved to the obsolete phase at the start of 2025, and ABB names the ACS580 general purpose drive as the series that replaced it. The ACS355 is in the limited phase, with sales being ramped down. Dimensions, wiring and fieldbus options differ between generations, so we check ABB's current replacement guidance against your type code before proposing a model.
What information is needed to replace an ABB flowmeter?
Send the order code and serial number from the nameplate of the sensor and of the transmitter if it is a remote version. Add line size, flange standard and rating, liner and electrode materials, power supply, output signals and any hazardous area marking. With that we can check whether the same model is current or which ABB successor applies.
Which certificates does ABB issue for process instruments?
Depending on the model and what is ordered, ABB supplies a factory calibration certificate, material certificates for wetted parts and the declarations and hazardous area certificates that belong to the device, such as ATEX or IECEx. Special requirements, for example additional calibration points or oxygen cleaning, have to be specified in the inquiry so they are included in the factory order.
Is Seven Star LLC a distributor of ABB?
No. Seven Star LLC is an independent supplier that sources ABB instruments, drives, breakers and relays through commercial channels. We check the type code or order code against the manufacturer's documentation, propose the manufacturer's successor when a model is obsolete, and provide ABB's datasheet and the certificates the manufacturer issues with the order on request.
