QMC utilizes the GWF line of thermal (BTU) meters for residential, commercial and institutional applications. Manufactured in Germany, these meters meet the highest international standards for accuracy and reliability, including EN1434 

The meters communicate through and are powered over an M-Bus 2-wire network. This helps to:

  • Reduce installation costs
  • Improve meter data integrity
  • Enable an unlimited product lifespan
