This device is not suitable for measuring cold water systems or fluids containing high levels of debris, sediment, or chemical additives that could damage the internal mechanical components. It is also not intended for use in industrial high-pressure steam lines or environments where the water temperature exceeds the manufacturer's specified operational limits.
Key specifications
Nominal diameter: DN20
Installation length: 130 mm
Nominal flow rate: 4 m3/h
Accuracy class: R100
Application: Hot water
To install the B-METERS hot water meter, ensure that the water supply is completely shut off and the pipe section is drained. The meter should be installed in a horizontal position with the dial facing upwards for optimal readability and accuracy. Use appropriate gaskets and fittings to ensure a watertight seal at both connection points. Once installed, slowly open the supply valve to allow water to fill the meter gradually, preventing pressure surges that could damage the internal turbine.
What to consider before purchase
Verify that the pipe diameter matches the DN20 specification
Ensure the available installation space is at least 130 mm
Check that the water temperature remains within the rated operational range
Confirm the orientation requirements for your specific plumbing layout
Usage recommendations
Regularly inspect the meter for any signs of leaks at the connection points and ensure the glass display remains clean and unobstructed for easy reading. If the meter is installed in a location prone to freezing, ensure adequate insulation is provided to protect the device.
