Manifold with flow meters Uponor Vario S FM 6X by Uponor

The Uponor Vario S FM 6X is a plumbing manifold with integrated flow meters designed to distribute and balance fluid circuits in heating and cooling installations. The unit provides six measuring channels to monitor and adjust flow rates for individual circuits, enabling hydraulic balancing and helping maintain stable system performance in residential and commercial underfloor heating and radiator systems.

Advantages

The manifold integrates flow meters directly into the distribution assembly, allowing precise visual indication of flow for each circuit without separate measuring devices. Its compact design facilitates neat installation in manifold cabinets or service niches, while robust construction is intended for long-term operation in potable water and heating systems. Built-in adjustment features simplify commissioning and rebalancing, reducing the need for additional components and on-site measuring equipment.

Suitable for

• Residential underfloor heating systems with multiple zones
• Small to medium commercial heating installations
• Radiator circuits requiring individual flow balancing
• Cooling circuits with distributed distribution requirements

Key specifications

• Number of flow channels: 6
• Integrated visual flow meters for each circuit
• Material: corrosion-resistant metals and engineering plastics suitable for heating/cooling fluids
• Compact manifold body designed for cabinet or niche mounting
• Adjustment capability for hydraulic balancing of individual circuits

How to use

Install the manifold in a suitable location accessible for operation and maintenance, following local plumbing codes and the system design. Connect supply and return piping to the designated inlet and outlet ports and attach each circuit to its corresponding outlet. Use the integrated flow meters to set and monitor individual circuit flow rates during commissioning; adjust the built-in valves to achieve the required flows for hydraulic balancing. After initial setup, periodically check flow meter readings to confirm continued balanced operation and readjust if system demands change.

Usage recommendations

During installation and maintenance, ensure system flushing and filtration to prevent particulate buildup in flow meters. Use appropriate sealing materials on threaded connections and follow manufacturer torque guidelines to avoid damage. For reliable performance in mixed-use buildings, perform commissioning with heat source or chiller running at typical operating conditions and document measured flows for future reference.
