Arcus KNX-IMPZ-WZ-M – KNX Water Meter with NZR Modularis WZK-M / WZW-M
The Arcus KNX-IMPZ-WZ-M is a smart KNX water meter designed for accurate measurement and monitoring of water consumption in residential and commercial environments. It is based on a certified NZR Modularis water meter (type WZK-M for cold water or WZW-M for hot water), featuring an integrated pulse module and a KNX-compatible data logger with battery backup.
Models are available for cold water up to 30 °C or hot water up to 90 °C, with installation lengths of 80 mm, 110 mm, or 130 mm. The device comes in a durable plastic housing for wall mounting and complies with protection class IP54/IP65.
