The Resideo EW110 Series single-jet dry water meters (previously known as Honeywell Home) are designed for the accurate measurement of cold or warm water in residential drinking water systems. Available in sizes DN15 to DN40, these meters feature a mechanical counter for reliable readings. For seamless integration into remote readout networks, they can be retrofitted with clip-on M-Bus or pulse output modules. Common sizes come equipped with factory-installed and configured M-Bus modules. The EW1100 water meters are engineered to handle cold water temperatures of up to 30 °C or 50 °C, while the EW1101 models are suitable for warm water applications with temperatures reaching up to 90 °C or 130 °C. Sizes DN15 to DN20 can be obtained with either a standard or extended flow range, similar to former EEC classes B and C. The larger sizes are designed with an extended flow range only, comparable to class C. **Special Features:** - Fully resistant to external magnetic fields - Retrofittable modules for wired M-Bus, pulse output, and RF communication Choose Resideo EW110 Series water meters for an efficient and reliable solution for your residential water system.
