MWA is excited to announce that B Meters’ brand-new water meter ranges, the GMDM-I and WDE-K50, are now in stock and available for next-day delivery from MWA.
Based in Italy, B Meters is a trusted and reliable meter producer that has been running for over 25 years. They produce over 2 million units per year, and with these two new additions to their selection you have better options for water metering than ever before.
Both GMDM-I and WDE-K50 have remote reading options available as standard, but B Meters have developed their own meter reading system.
No longer do you need to invest in a costly, annual subscription third-party reading system as B Meters have you covered. With a one-off software licence, B Meters can supply a reading system with their range of receivers.
With this new system, you can have access to the most useful metering information at a fraction of the cost.
