ARCUS-EDS 60201-75124515 NZR Modularis WZW-M hot KNX water meter

ARCUS-EDS 60201-75124515 Product Description

<p The ARCUS-EDS 60201-75124515 water meter, called KNX NZR Modularis WZW-M, is a specialized device for measuring hot water consumption. This meter is part of the WZ-M series and is produced in collaboration with the NZR northwest German meter.

Technical characteristics

<p The WZW-M meter is designed to operate in temperature conditions up to 90°C, making it ideal for use with hot water.

• Nominal flow rate: 2.5 m³/h
• Nominal Diameter: 20 mm
• Maximum flow rate: 5 m³/h
• Installation Length: 130 mm

Functionality

<p The meter is equipped with an integrated pulse module and complies with MID standards, being sealed and calibrated. It offers the possibility of measuring volume flow or electrical capacity.

• Flow Measurement: Volumetric or Electrical Capacity
• Flow Measurement Period: Per Second, Per Minute, Per Hour, or Per Day
• Use of Daylight Saving Time: Yes or No

Security and Protection

<p To prevent unauthorized consumption resetting, you can assign a PIN (0 to 65535). If the PIN is set to 'zero', the reset function is disabled.

Integration with the KNX System

<p The meter includes an integrated KNX bus coupling unit and does not require an auxiliary power supply. It operates with an EIB/KNX bus voltage between 21 and 32 VDC, with a power consumption of about 240 mW at 24 VDC.
