About us

AMS Instrumentation & Control Ltd (AMS IAC) have built on the established foundations that the Alan Cobham brand laid down in the Rail Industry almost 60 years ago.

AMS-IAC was created as the product manufacturing division of AM Sensors Ltd, a specialist instrumentation and control engineering business, founded in the 90’s. In 2019 we completed the process of formal separation and have continued to develop as a leading supplier of level products and control valves into the Rail Industry from our facility in Cornwall.

Our customer approach is to solve specific needs and provide our customers with solutions that best suit their requirements. We offer flexible solutions, from a complete turnkey supply to individual component upgrades to existing systems, whichever option is best suited to the application. We advocate, wherever possible, the refurbishment of existing equipment; especially where there is no substantial benefit in replacement.

Our aim is to supply quality products at competitive prices with excellent customer service.

Product Information

No 1 for fuel filling spill prevention
Used as standard on most fleets in the UK rail industry our filling valves (Flyte valves) and dry break couplings provide a complete safety and environmental solution to fuel tank filling requirements.

Refurb options preventing waste
Intentionally designed to be broken down into a number of maintainable components, AMS IAC have provided factory refurbishment plans and spares parts options for our refuelling control (Flyte) valves and couplings. This has been proven to prolong the life of the products and provide the end user with a significant cost saving.

Helping clients with obsolescence
To overcome an issue with spares supply and quality of another manufacturer’s old brass coupling design; working with clients we used our engineering resources to design and build a reliable, lower cost and lighter, direct fit replacement. This has proven to have reduced maintenance costs, fewer leakages and increased reliability.”
