A 25-year partnership you can trust
Since day one, MWA has proudly partnered with Metrix to supply high-quality UG-G BS746 diaphragm gas meters across the UK. It’s not just a long-standing collaboration, but an exclusive one. We’re the only official UK provider of Metrix gas meters, and after 25 years, the relationship is stronger than ever.
With formal MAM approval, full MID certification, and ongoing product excellence, our partnership continues to raise the bar for gas metering quality and reliability.
Meet the industry favourites: G4 & G10
While Metrix offers a complete portfolio of metering products, it’s the G4 and G10 diaphragm gas meters that stand out in the UK market. These are the meters trusted by utility providers, housing developers, and commercial contractors alike – and for good reasons:
25-Year Exclusive UK Partnership
MWA has been the sole UK supplier of Metrix meters for 25 years. That long-standing commitment itself signals trust from both the manufacturer and the UK market.
High Volume Sales
G4 and G10 are the most-supplied models through MWA – they outsell other diaphragm meters in the portfolio, showing strong demand and repeat use by installers and specifiers.
MAM & MID Approval
Being MAM-listed (UK compliance) and MID-certified (EU-wide accuracy standards) means they’re approved for regulated, high-accuracy environments – something procurement and compliance teams trust.
Broad Use Cases
G4 is a go-to for residential use; G10 is widely used in commercial settings. This dual fit gives them a trusted footprint across both sectors.
Fireproofing & Safety Compliance
Both meters are tested to 650°C fireproofing and EN1359, making them durable and compliant with safety standards.
Metrix G4: Residential workhorse
Compact, lightweight, and fireproof up to 650°C, the G4 is the go-to diaphragm gas meter for residential installations. With BS746 connections, optional M-Bus output, and temperature compensation versions available, it delivers accuracy and safety in equal measure.
Max flow rate: 6 m³/h
MID approved & EN1359 compliant
Optional unions and brackets available
Pulse output ready (1 imp = 0.01 m³)
Metrix G10: Commercial performance

Fireproof up to 650°C
Pulse output ready (1 imp = 0.1 m³)
