Product Information

Full details

The Reliance Valves Metering Station (DN40) is an essential tool for professional HVAC and plumbing engineers who require precise water flow measurement for system commissioning. By integrating seamlessly with manual balancing valves, this unit allows users to achieve designed flow rates and ensure peak hydronic system efficiency; however, it requires professional installation and specialized diagnostic tools to capture and interpret the flow readings effectively.

FAQs

Can this station be used on steam systems?

No, this device is designed specifically for hydronic water-based heating and cooling systems.

Does the unit come with a flow gauge?

No, the metering station is a sensor component; a separate portable flow computer or pressure gauge is required to read the data.

What is the maximum pressure rating?

Please consult the technical data sheet provided with your specific unit as pressure ratings vary based on the operating temperature.

Is it possible to install this vertically?

Yes, provided the flow direction is consistent with the arrow marked on the valve body.

Does the unit require regular maintenance?

The unit is largely maintenance-free, but test ports should be inspected periodically for signs of debris or gasket wear.

Troubleshooting

No pressure reading at the metering point

Verify that the isolation valves are open and that the test point probe is fully inserted into the sensor port.

Erratic or fluctuating flow data

Check for trapped air in the system and bleed the line before attempting a new measurement.

Leakage at the test port

Ensure the test port cap is properly tightened and the internal o-ring is not damaged.

Pros and Cons

Pros

  • High accuracy in flow rate measurement
  • Essential for balancing complex hydronic systems
  • Robust construction for long-term reliability
  • Streamlines the commissioning workflow

Cons

  • Requires professional hydraulic knowledge for installation
  • Necessary diagnostic tools for reading the station are sold separately
  • Not suitable for residential-scale low-flow applications

Setup, Compatibility & Care

Installation must be performed by a qualified plumber or HVAC technician to ensure the station is oriented correctly in the direction of flow. Always check that the DN40 size matches your existing pipework.

Setup Steps:

  1. Identify the designated location on the circuit following the balancing valve.
  2. Ensure the flow arrow on the unit points in the direction of water travel.
  3. Secure the connections using compatible fittings to prevent leaks under system pressure.
  4. Once installed, verify the seal by pressurizing the system before closing any wall cavities or insulation.

Care: Keep the test ports free of debris and ensure caps are tightened when not in use to prevent internal fouling or external leakage.
