This residential water meter is commonly used in domestic hot water systems in single-family homes and small apartment units. It is suitable for installations where accurate measurement of hot water consumption is required, such as in bathroom and kitchen circuits. The meter is designed to operate in systems with a maximum temperature of 90°C and is typically installed in accessible locations for easy maintenance and reading. It is often integrated into heating and plumbing systems where individual consumption tracking is necessary for billing or monitoring purposes.

Installers working on domestic hot water systems will find this meter suitable for use in both new constructions and retrofit projects. It is compatible with standard plumbing layouts and can be connected to central heating systems or standalone hot water circuits. The meter is not intended for use in high-pressure or industrial applications and should be installed according to the manufacturer's guidelines to ensure accurate readings and long-term reliability.

Technical parameters

Code	I009996.01
Brand	IVAR

The nominal rate of 1.5 m³/h indicates the maximum volume of water the meter can measure under normal operating conditions. The 90°C maximum operating temperature ensures compatibility with domestic hot water systems. These parameters are essential for sizing the meter correctly to match the system's flow requirements and thermal conditions.

Installation and connection

The IVAR I009996.01 is designed for 1/2 inch pipe connections and should be installed in a straight section of the pipeline to ensure accurate flow measurement. The installation procedure involves cutting the pipe, fitting the meter with appropriate thread sealant or gaskets, and securing it with compression or threaded fittings. It is important to verify that the meter is installed in the correct orientation and that the flow direction matches the arrow on the meter housing. Common installation mistakes include insufficient straight pipe lengths before and after the meter and incorrect sealing, which can lead to measurement errors or leaks.

Compatibility and accessories

This water meter is compatible with standard domestic hot water systems and can be integrated with existing plumbing components such as valves, pressure regulators, and flow control devices. For installation, it may be necessary to order additional fittings such as compression nuts, washers, and thread sealant. No specific accessories are required unless the system includes a data logging or remote reading interface, which is not part of the standard product.

Technical background for designers

The IVAR I009996.01 operates on a mechanical or electronic flow measurement principle, depending on the internal design, and is constructed from materials suitable for hot water environments. The meter is integrated into the system via its 1/2 inch connection and is designed to provide a cumulative consumption display. The service life and efficiency of the meter are influenced by the quality of installation, the presence of particulate matter in the water, and the operating temperature. Regular maintenance and adherence to installation guidelines are key to ensuring long-term performance.

Service and operation

Periodic inspection of the meter is recommended to ensure accurate readings and to check for signs of wear or blockage. The meter should be cleaned if necessary, and the sealing components should be inspected for integrity. No specific service intervals are provided in the technical data, but it is advisable to follow the manufacturer's recommendations for maintenance and calibration.

Frequently asked questions

Can the IVAR I009996.01 be used in cold water systems?
Yes, the meter is suitable for use in both hot and cold water systems, provided the temperature does not exceed 90°C.

Is the meter compatible with digital monitoring systems?
It depends on the internal design of the meter. If it includes an electronic output, it can be integrated with digital monitoring systems. Otherwise, it provides only a mechanical display.

What is the maximum pressure rating of the meter?
The pressure rating is not specified in the product data. It is recommended to refer to the manufacturer's technical data sheet for detailed information.

Can this meter be installed in a vertical pipeline?
Yes, provided the flow direction is aligned with the arrow on the meter housing and the installation allows for proper flow measurement.
