About us
Seven Star LLC Engineering Service Company
Seven Star LLC is a team of dedicated engineers and procurement specialists supplying instrumentation, automation, and mechanical equipment to oil, gas, petrochemical, power, and water/wastewater projects across Oman. We are the official authorized representative in Oman for the manufacturers listed on our Agencies page, and a supplier of products from more than 440 global manufacturer brands, delivered with the manufacturer’s documentation and calibration certificates where the manufacturer provides them. Availability and lead time are confirmed at quotation.
Rather than acting as a generic reseller, our engineering team gets involved at the specification stage: matching the right sensor, valve, or control system to your process conditions, sourcing it from the manufacturer or its distribution network, and supporting it afterwards with spare parts. That is the model behind every one of the departments below.
Seven Star LLC offers its capabilities across the following specialized departments:
Metering & Prover Solutions — flow measurement and custody-transfer verification systems for fiscal metering applications.
Automation & Control Solutions — PLCs, DCS, ESD, and industrial communication systems for process control.
Analyzer & Sampling Systems — process analyzers and sample conditioning systems for accurate, continuous process monitoring.
Rotating Equipment Solutions — parts and diagnostic tools to keep pumps, turbines, and compressors running reliably.
Calibration Instruments — portable and bench calibration equipment to keep field instrumentation within tolerance.
Procurement Products — our full instrumentation and industrial-supply catalog, supplied on request.

Is Seven Star LLC a distributor of the brands on this website?
We are the agency for Dakota NDT, Winsonic and pFlow in Oman and the GCC. For all other brands we are an independent supplier: we source the products through the manufacturer or its distribution network and provide the manufacturer's documentation with the order on request.
Which industries and countries do you supply?
Most of our customers are in oil and gas, petrochemical, power generation, and water and wastewater. We supply end users, maintenance contractors and EPC companies in Oman and the other GCC countries.
How do you make sure I receive the right part?
Before quoting we compare your model number or order code with the manufacturer's documentation and check range, material, approvals and options. If something is missing or does not match, we ask you first. A nameplate photo of the existing unit helps a lot.
Which documents can you provide with an order?
On request we provide the manufacturer's datasheet and manual and the certificates the manufacturer issues for the item, for example a certificate of conformity, a calibration certificate or material certificates. Tell us what your project requires when you send the inquiry.
How do I request a quotation?
Use the inquiry form on the website or the details on the contact page. Give the brand, the full model or part number, the quantity and, if you have one, the datasheet or a nameplate photo. For a project list you can send the whole list at once.
