Smarter metering engineered for industry
The UK loses nearly three billion litres of treated water to leakage every single day. For industries managing extensive networks, even minor inefficiencies can turn into major costs.
At MWA, we believe the solution begins with better data. That’s why we’ve partnered with B Meters to deliver the HYDRODIGIT-S1. This high-performance digital water meter brings industrial-strength reliability and cutting-edge metering capability into one smart, compact unit.

These meters are a great solution to the need to upgrade legacy infrastructure, implement building automation, or roll out smart metering on a large scale. The HYDRODIGIT-S1 delivers plug-and-play simplicity, seamless integration, and long-term reliability.

Key features:
- IP68-rated – fully protected against dust and water
