Zenner MNK-N Multi Jet Inline Water Meters (15-50mm BSP)

The Zenner MNK-N is a precision-engineered, multi-jet inline cold water meter designed for residential and commercial metering applications. Built with a wet-dial register, UV-resistant plastic lens, and a high-quality brass body, it offers reliable, tamper-resistant performance for service connections.

This meter is fully MID-compliant and features low starting flow, minimal bearing load, and long service life. The MNK-N can be retrofitted with a reed switch pulser for remote monitoring or integration into smart metering systems via LoRaWAN® or wireless M-Bus protocols.

The meter can be installed in both horizontal and vertical positions (including ascending or descending pipe runs), and its compact design makes it ideal for confined installations.
