Regulating flow meter - for IVAR manifolds - 5/4"; EK IVAR.KIT FLC 20

Product detailed description

Flow meters are essential components in hydronic heating systems, particularly in multi-circuit manifolds used in residential and commercial buildings. These devices enable precise control of flow rates in individual circuits, ensuring balanced distribution and efficient system operation. Installers working with IVAR manifolds often encounter the need to integrate flow measurement and regulation into the system design, especially when combining different heating methods such as underfloor heating and radiators. Proper installation and calibration of flow meters help maintain system performance and prevent issues such as thermal imbalance or excessive pressure drops.

The operating temperature of +90 °C and nominal pressure of PN 10 are critical for selecting the correct flow meter for the intended application. These parameters ensure compatibility with standard heating system conditions and help in determining the appropriate flow range and material resistance. The specified flow range of 0 to 5 l/min is suitable for circuits with moderate flow requirements, making it ideal for manifold systems where individual circuit regulation is necessary.Installation and connection When installing this flow meter, ensure it is connected to the manifold using the correct 5/4 inch thread type. Verify that the flow direction matches the manufacturer's specifications to avoid incorrect readings or damage. A common mistake during installation is neglecting to flush the system before commissioning, which can lead to blockages or inaccurate measurements. Always follow the manufacturer's instructions for mounting and sealing to prevent leaks and ensure long-term reliability. Check the alignment of the meter with the manifold and confirm that all connections are tight and secure before system activation.

Compatibility and accessories

This flow meter is specifically designed for use with IVAR.CS 553, IVAR.CI 553 and IVAR.CI 557 manifolds. It is not compatible with other manifold types or systems outside the IVAR range. When ordering, ensure that the manifold model is compatible with the flow meter. Additional accessories such as sealing materials and mounting brackets may be required for a complete installation. Refer to the manufacturer's documentation for a list of recommended components.

Technical background for designers

The flow meter operates by measuring the instantaneous flow rate of the heating medium through the circuit. It is constructed from PPA and ABC plastics, which offer resistance to thermal and chemical stress in heating systems. The design allows for integration into manifold systems without disrupting the flow dynamics. The accuracy of the meter is influenced by the cleanliness of the system and the stability of the flow conditions. Regular maintenance and system flushing are essential to preserve the meter's performance and extend its service life.

Service and operation

To maintain the flow meter's functionality, it is recommended to flush the entire heating system before commissioning, especially when combining different heating methods. This helps remove debris and contaminants that could affect the meter's readings. The use of a system treatment such as GEL.LONG LIFE 100 is advised to prevent corrosion and scaling. While no specific service intervals are provided, periodic inspections for leaks, blockages or signs of wear are recommended to ensure continued operation.

Frequently asked questions

Can this flow meter be used with other IVAR manifold models besides those listed?
No, it is specifically designed for use with IVAR.CS 553, IVAR.CI 553 and IVAR.CI 557 manifolds. Compatibility with other models is not guaranteed.

What should be done if the flow meter shows inconsistent readings after installation?
Check the system for blockages or debris and ensure the flow direction is correct. If the issue persists, consult the manufacturer's technical documentation for troubleshooting steps.

Is it necessary to use the recommended system treatment during installation?
Yes, using a treatment such as GEL.LONG LIFE 100 is advised to prevent corrosion and scaling, which can affect the meter's performance and longevity.

Can this flow meter be used in systems with higher operating temperatures?
No, the maximum operating temperature is specified as +90 °C. Use in systems with higher temperatures may cause damage or inaccurate readings.
