Simple science.
Real savings.
Standard water meters can't tell the difference between water and air. Here is how W&G Global Saver resolves the issue permanently.
Air enters your pipes
Every time water pressure fluctuates, air gets trapped inside your water supply pipes — invisible, but costly.
Your meter counts it
Your water meter registers air as water volume. You're billed for cubic metres of nothing.
W&G removes the air
Our device fits inline on your supply pipe and continuously purges trapped air before it reaches your meter.
Your bills drop
With air removed, your meter only counts real water. Customers save up to 35% from the very first month.
Field Test Results
Two ISO 4064–certified water meters installed side by side under identical conditions. One fitted with the W&G Air Block — one without. The results speak for themselves.
Without W&G
0002557 m³
With W&G Air Block
0002130 m³
SAVING
Proof, not promises
Under controlled field conditions, the meter fitted with the W&G Air Block recorded 427 fewer units than the unmodified meter over the same period — a 35% average reduction in recorded consumption. No electricity. No maintenance. No specialist installation.

Pressure & Flow Test
Side-by-side jet height comparison — W&G line vs control line under identical supply pressure. The W&G-fitted line produced a measurably higher, further-reaching jet with no pressure loss observed.
