Residential water meter - with the possibility of adding a communication module - 1,5m3; 3/4"; 110mm IVAR.WFW

Product detailed description

Residential water meters are essential components in modern plumbing systems, particularly in multi-unit buildings and individual homes. They provide accurate measurement of water consumption and support efficient billing and resource management. This model is suitable for both new installations and retrofitting in existing systems where precise water usage tracking is required.

The device is commonly installed in residential properties, including apartments and single-family homes. It is integrated into the water supply line to measure the flow of both cold and hot water. The installation process requires careful alignment with the system’s piping and adherence to manufacturer guidelines to ensure reliable operation over time.

Technical parameters

Installation and connection

Installation should be carried out by qualified personnel to ensure proper alignment and secure fitting. The device connects to the water line using a 3/4 inch threaded connection. Before fitting, the pipeline should be cleaned to remove debris that could damage the meter or affect accuracy. Ensure the meter is installed in a straight section of pipe, away from bends or turbulent flow areas. A common mistake is incorrect orientation, which can lead to inaccurate readings. Always verify that the flow direction matches the arrow marked on the device body.

Compatibility and accessories

This water meter is compatible with the IVAR.WFZ 311 M-Bus communication module and the IVAR.WFZ 661 wireless adapter for integration with the WalkBy system. These modules must be ordered separately and fitted according to the manufacturer’s instructions. For optimal performance, ensure the selected communication module is compatible with the existing monitoring infrastructure.

Technical background for designers

The meter operates on a mechanical or electronic principle to measure water flow through the system. It is constructed from durable materials suitable for long-term exposure to water at varying temperatures. The integration into the system depends on the flow rate and pressure conditions, which must be within the device’s specified range for accurate measurement. Factors such as sediment buildup or chemical corrosion can impact service life and require regular inspection to maintain efficiency.

Service and operation

Periodic inspection is recommended to ensure the device continues to function correctly. Check for signs of wear, blockages, or leaks around the connections. If the communication module is used, verify that the signal strength remains stable and that data transmission is uninterrupted. No specific service intervals are provided in the documentation; refer to the manufacturer’s technical data sheet for detailed service recommendations.

Frequently asked questions

Can the meter be used in both cold and hot water systems?
Yes, the device is suitable for both cold and hot water applications depending on the model selected. The IVAR.WFK variant is designed for cold water, while the IVAR.WFW variant is intended for hot water.

Is it possible to integrate the meter with a remote monitoring system?
Yes, the device supports remote reading via M-Bus when connected with the IVAR.WFZ 311 module. Wireless integration is also possible using the IVAR.WFZ 661 adapter.

What is the maximum flow rate the device can handle?
Refer to the manufacturer’s technical data sheet for detailed specifications regarding flow capacity and pressure limits.

Does the meter require a power supply for operation?
Basic metering functions do not require external power. However, the communication modules may need a power source for data transmission and remote monitoring capabilities.
